Fluids

PDR Advice on What to Pour into Your Vehicle

Changes in vehicle design and manufacture have resulted in changed fluid requirements for our vehicles. With the sophistication of engines, transmissions, differentials, etc., it's best for Urbana residents to always use the proper type of fluid for their vehicle. Using incorrect fluids can actually damage your engine.

As engines have become more sophisticated, new weights (or grades) of engine oil have been introduced. Today, there is a much wider range of weights for engine oil as well as a variety of formulations for different types of engines.

Transmission fluid, brake fluid and coolant/anti-freeze have changed because the materials that go into making the systems they protect have changed. The fluids in our vehicles generally have two jobs: to lubricate and to prevent corrosion. The fluids formulated for your vehicle are specifically designed to protect the materials that make up its engine parts. Using the wrong fluid may leave some parts vulnerable to corrosion. Further, using the wrong fluids can also void your vehicle's warranty. So PDR recommends Urbana drivers follow the fluid recommendations in their owner's manuals.

Vehicle fluids, including engine oil, are also designed in special formulas for higher mileage vehicles. These formulas contain additives that help clean older engines and transmissions as well as recondition older seals and gaskets. These fluids are perfectly okay for your vehicle as long as you match the original fluid recommendations in your owner's manual. In other words, a high-mileage oil is fine as long as it is the same weight as the oil recommended by your vehicle's manufacturer.

Good vehicle care always includes proper attention to your vehicle's fluids. Understanding and using correct fluids will keep your vehicle running well and will help prevent early corrosion and wear of vital engine parts.

Does My Choice in Oil Affect Change Intervals?

Oil changes are probably the most recognized service on a vehicle. Almost all Urbana residents know about them. But do we know enough?

Several decades ago, oil changes were fairly standard: every three months or 3,000 miles or 5,000 kilometers. But recent advances in both engine technology and oil quality have led to longer oil change intervals.

Delayed or skipped oil changes are a problem for Urbana residents because they lead to the build-up of oil sludge in your engine. Oil sludge forms when engine oil breaks down, which happens with both time and miles. Obviously, driving will take its toll on engine oil, but the oil also breaks down even as the vehicle just sits in the garage. This is why oil change intervals are listed in both time and distance traveled, and the phrase “whichever comes first” is applicable.

Oil sludge is essentially petroleum jelly. Imagine this stuff squishing around in your vehicle engine, pushing into small engine passageways and blocking passage of oil to vital engine parts, shortening your engine's life expectancy.

To prevent sludge, you have to get your oil changed regularly, as often as the manufacturer recommends. Check your owner's manual for every vehicle you own to know the interval for each one. Don't assume they will be the same.

If you tow a trailer, haul heavy loads, make a lot of short trips around Urbana, usually engage in stop-and-go (or around-the-town) driving, drive in cold or hot Illinois weather, or drive in polluted or dusty conditions, you may need to change your oil more frequently. Check your vehicle's owner's manual for a “severe service” recommendation.

If the manual doesn't give you the advice you need, talk to your friendly and knowledgeable PDR service advisor. He will be able to answer any questions about preventive maintenance or vehicle care that you may have, including how often to change your oil.

Urbana residents need to get the right weight and type of oil recommended for their vehicles. More and more are using synthetic oil in their vehicles. Synthetic oil typically lasts longer and is more resistant to sludge formation than conventional motor oil. But it is also more expensive. So it can be tempting for Urbana residents to ask for conventional oil, but if you replace synthetic oil with conventional oil, you will have to change your oil more often to prevent sludge build-up. In the end, you're probably not saving money at all.

Also, your engine may not be designed for the conventional oil. Check your owner's manual before replacing synthetic oil with conventional.

The PDR Basic Guide To Synthetic Oil

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.

Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.

Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.

Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.

Remember that marbles and pencils thing we were talking about? Well, that makes synthetic oil slipperier than conventional oil which means less friction in your engine. Your vehicle engine runs cooler, wears less and lasts longer. You also get a boost in power and maybe even an improvement in fuel economy.

Synthetic oil also lasts longer so you change it less often – which is great for the environment. With longer oil change intervals, you need an oil filter specifically built for the longer service life of synthetic oil. Talk with your friendly and knowledgeable PDR service adviser about synthetic oil and synthetic blends – they might be just what you need to improve engine performance and extend the life of your vehicle.

The PDR Guide to Proper Fluids for Your Vehicle

The automotive professionals at PDR would like to give Urbana drivers an update on some of the things happening in automotive fluids. You know, vehicles are becoming more sophisticated every day.  Fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The Urbana do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many Illinois ] owners rely on the advice of their friendly and knowledgeable PDR service advisor to not only get the correct family of fluids, but to suggest the formulation that is best for their vehicle and their driving habits in the Urbana area.

Let's start with engine oil. Urbana drivers who have been paying attention will have noticed a number of new oil weights on the Illinois scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. The vehicle manufacturers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your Urbana service center will know what weight your vehicle manufacturer recommends - and it's important to follow those recommendations. Your service advisor at PDR can also offer suggestions for special formulations and can tell you all about conventional and synthetic oils.

Antifreeze, or engine coolant, is another area that has become more complicated. For a long time, vehicle manufacturers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that vehicle manufacturers are using to build the cooling system. Using the wrong type of coolant in your vehicle can actually void your warranty, so it's important to get that right.

Transmission fluid is becoming specialized for Urbana vehicles as well. New transmission designs have particular requirements that require specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids Illinois drivers need will grow. And, some of the formulations will cost a little more for Urbana drivers. Fortunately, PDR will continue to update their training to keep pace with technology so that you'll get the right fluids your vehicle needs. It's all part of the commitment we make to your driving peace of mind.

Illinois: What Is the Risk of High Oil Change Intervals?

Illinois residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.

Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.

So what is a good time interval for oil changes? How do Illinois residents know when to change it? And why do we change it in the first place?

Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for Illinois residents. What you really want to avoid is called oil sludge.

Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.

Sludge forms rapidly in an engine that is driven under what are termed “severe conditions.” A vehicle's owner's manual includes recommendations for oil change intervals under both normal and severe conditions. Severe conditions include towing a trailer, driving in polluted or dusty conditions, hauling heavy loads or using a car top carrier. Also, extremes in climate such as very hot or very cold temperatures constitute severe conditions for vehicles.

Some people may be tempted to overlook the severe conditions preventive maintenance schedule in their 's owner's manual because of the word “severe.” But consider this: the most common form of severe conditions is stop-and-go driving, rush hour commuting or only driving your vehicle on short trips around the area.

When a vehicle only makes trips under four miles/six kilometers, or under 10 miles/16 kilometers in freezing conditions, the engine doesn't get warm enough for condensation in the oil to evaporate. The result? You get oil sludge build-up. If your driving patterns are the same as any of the conditions that count as severe, you should be changing your oil more frequently under the severe conditions schedule. 

The team at PDR in Urbana can help you understand what type of oil to use in your vehicle and how it can affect your oil change schedule. Some vehicles are filled with synthetic or synthetic-blend oil at the factory. The owner's manual will recommend that this oil continue to be used in the vehicle, and oil change intervals will be based on this type of oil.

Also, if your vehicle uses conventional oil, but you have some of those severe driving habits we talked about, you can switch to a premium-grade oil to give your vehicle extra protection. The answer to why we change our oil is fairly simple: to protect our engines and make our vehicles last longer and run better. But the answer to how often to change our oil is more complex: it depends on our vehicle, our driving habits, where we live and what kind of oil we use.

When it comes to oil changes, a little information can go a long way to helping people save money and extend the life of their vehicles. Stay safe, and stay on the road.

PDR Service Tip: Why Synthetic Oil Is Good For Your Vehicles

Hello Illinois! Today's vehicle care topic is: Synthetic Oil vs. Petroleum Based Oil. Synthetic motor oil is a substitute for petroleum based oil. If you aren't currently using it, why not? Synthetic motor oil maximizes engine power and fuel economy. To see why, we'd need a microscope, so we'll have to settle for using our imaginations. The molecules of conventional motor oil are long hydrocarbon chains. Synthetic motor oil, on the other hand, has uniform, round molecules. Which is slipperier, a pile of pencils or a pile of marbles?

Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at PDR in Urbana.)

Some manufacturers are extending oil change intervals for many models. The added protection of synthetic oil covers you for these longer intervals. Talk with your PDR service advisor about how you drive in and see if he thinks you can benefit from synthetic oil for your vehicle. Also ask about the appropriate oil change interval for synthetic, because it may very well be longer than for conventional oil.

Most of us have a busy life and occasionally miss an oil change; go ahead, admit it. Since we're not perfect, doesn't it make sense to use a motor oil that's got your back?

What about price? Petroleum based oil may appear to win out on this point, but let's consider all the facts. Although synthetic oil costs more, it lasts longer, protects your vehicle engine better and increases fuel economy. You'll likely save money in the long run. If you're serious about making your vehicle last longer, consider using synthetic motor oil.

PDR Guide to Using the Correct Fluids in Your Vehicle

Today's PDR post focuses on using coolant. drive If you pour in the wrong kind, it won't protect the cooling system and may even void the warranty. Check your vehicle owner's manual. Of course, your PDR service advisor will know the proper coolant for your vehicle.

Brake fluid is confusing for some Urbana drivers. Back when we opened PDR, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Urbana residents mistakenly think the higher numbers are an upgrade. You know, if 3 is good then 4 must be better. That's not how it works. They are different formulations to meet the demands of differences in brake systems. Only one of them is designed for your vehicle.

Ditto for transmission fluid. For decades there were two basic types of tranny fluid used at PDR: friction modified or not. With the tremendous engineering advances in vehicle automatic transmissions, there have been several new types of fluids developed to protect and lubricate them.

Nowhere are the advances in automotive fluids more evident to PDR professionals than in motor oil. Many new weights and formulations have been created to meet the demands of today's high-tech vehicle engine design. Modern engines have more parts and much tighter tolerances.

That's where the new grades of engine oil come in. They have to be formulated to lubricate, protect and clean all of those vehicle engine parts, big and little. The oil has to be thin enough to get into little passages, yet resistant to vaporization.

At PDR in Urbana, we believe that in some ways modern automotive fluids are just as impressive as the new engines. Because weights of oil and types of coolant and transmission fluid are so carefully matched to the vehicle, make sure you always use the proper fluid if you are topping off at home.

Super Slick at PDR in Urbana: Synthetic Oil

When you get an oil change, it's always a safe bet to just use the type of oil the manufacturer recommends. But sometimes we're asked if we'd like conventional or synthetic motor oil. We glance at the price tags on the two options and choose the cheaper one. But in this case, the more expensive oil might be the better bargain for Urbana drivers.

Conventional oil is made from petroleum. Its molecules form long hydrocarbon chains. Synthetic motor oil is either more highly refined petroleum or completely man-made. Its molecules are more uniform. This provides advantages over conventional motor oil.

First of all, the molecular structure of synthetic motor oil makes it more slippery than conventional oil so it lubricates better. This translates to better wear protection for Urbana drivers, cooler operating temperatures and more engine power.

Further, synthetic oil is more heat-resistant than conventional oil, and it doesn't vaporize as easily. It provides better protection for severe conditions like stop-and-go driving around Urbana and very hot or freezing Illinois temperatures.

Also, synthetic oil doesn't generate oil sludge like conventional oil. This prevents small engine passageways from becoming clogged, which can significantly extend the working life of your vehicle engine.

Manufacturers are aware of the advantages of synthetic oil, and many of them are using it to fill their vehicles before delivering them to be sold. Many owner's manuals now come with the recommendation to use only synthetic oil. Because synthetic oil wears better and protects better than conventional motor oil, it can be changed less often. If your vehicle came with a recommendation for synthetic oil, you may have noticed that the recommended period between oil changes is longer than what you're used to. However, if you switch to conventional oil, you need to be aware that you can't follow this longer service interval. You'll have to change your oil more often.

On the other hand, if you are using conventional oil and you switch to synthetic oil, you may be able to lengthen the time between oil changes. You can ask the pros at PDR for more information. They can offer you good auto advice about oils and service intervals based on your driving habits and requirements.

Oil changes are the hallmark of preventive maintenance at PDR. All Urbana drivers need them. So we should get excited about a product that reduces how often we need them. Synthetic oil is more expensive, yes, but it can pay for itself by lasting longer than conventional oil. And when you add in the hidden savings of an extended engine life and improved fuel economy, not to mention increased engine power, there's a good chance that synthetic oil actually saves cash in the long run. All Urbana drivers pay for vehicle care. But understanding what we're paying for can make us more savvy shoppers.

The Right Fluids for Your Vehicle

The current vehicles in the market have over a century of engineering behind them. They have evolved into complex and powerful machines. Developments in their engines, however, have coincided with advances in many other vehicle components, including the fluids.

It's up to people in Urbana to always use the right type of fluid for their vehicle. Your service advisor and your owner's manual are resources for auto advice on exactly what types of fluid your vehicle needs. Improper fluids can damage your vehicle and void your warranty.

Some of the fluids that have changed significantly in recent years are cooling system fluid, brake fluid, transmission fluid and motor oil. Each of these comes in many varieties now, and it's hard to know exactly which one your vehicle needs.

Cooling systems were once made of iron, steel and rubber. One coolant could be used to protect all of these materials. But new cooling systems have components made from a variety of metal alloys and several kinds of plastic, and coolants now contain additives that protect these various materials from corrosion. Since the materials vary among manufacturers, they require different additives, which means there are now several coolants on the market. The type of coolant your vehicle needs depends on the materials used in its cooling system.

Most vehicles used to require DOT 3 brake fluid. But now many vehicles need DOT 4 or DOT 5. Some Urbana drivers mistakenly think the higher numbers reflect an increase in grade—that DOT 4 is somehow better than DOT 3. But the truth is, the numbers represent variations in formulation. The different formulas have evolved to meet the demands of newer and better brake systems. For a long time, transmission fluid came in two varieties: regular and friction-modified. But transmissions have come a long way recently and so have the fluids that protect and lubricate them. There are several new types of fluid on the market, but your vehicle is designed for just one of them.

Of all the automotive fluids, motor oils have experienced perhaps the greatest advances in engineering and technology. A number of new weights and formulations have recently been developed to meet the needs of modern engines, which have more parts and tighter tolerances than ever before. Engines have become more sophisticated and complicated, but they have also increased in power and fuel efficiency. Despite these changes, Urbana vehicles still need them to be highly durable.

That's the job of motor oil. Motor oil still has to perform its original function—lubricating and protecting the engine. It is formulated to help clean the engine as well. Modern motor oil also has to be thin enough to penetrate small engine passages yet still be resistant to vaporization.

Specialized motor oils have also been developed for high-mileage vehicles. If your vehicle has 75,000 miles/120,000 km or more on it, you might consider switching to one of these motor oils. They contain extra detergents that help clean older engines, additives that condition seals and gaskets that can become brittle with age. High-mileage motor oils come in weights and types just like regular motor oils, and Urbana drivers should match the proper weight and type of high-mileage oil to their vehicle in the same way you would regular motor oil.

Over time, vehicles have developed in complexity and variety, and their fluids have developed as well. Each vehicle is matched to a set of fluids that meet its specific requirements. Illinois vehicle owners should take care to learn their vehicle's fluid requirements before topping off at home. A large part of preventive maintenance for Urbana drivers is making sure your vehicle's fluids are clean and adequate, but they must be the proper type as well. As our vehicles become more sophisticated, car care becomes more sophisticated as well.

Learning about proper fluids for your vehicle will help you maintain its performance and prolong its life. Talk to us at PDR in Urbana.
