The automotive professionals at Clayton's Auto Service would like to give Corvallis 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 Corvallis 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 Oregon ] owners rely on the advice of their friendly and knowledgeable Clayton's Auto Service 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 Corvallis area.
Let's start with engine oil. Corvallis drivers who have been paying attention will have noticed a number of new oil weights on the Oregon 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 Corvallis service center will know what weight your vehicle manufacturer recommends - and it's important to follow those recommendations. Your service advisor at Clayton's Auto Service 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 Corvallis 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 Oregon drivers need will grow. And, some of the formulations will cost a little more for Corvallis drivers. Fortunately, Clayton's Auto Service 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.
Corvallis 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 Corvallis 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 Corvallis 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 Oregon 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 Corvallis drivers.
Corvallis residents 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, or only driving your vehicle on short trips around Corvallis.
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 Clayton's Auto Service in Corvallis 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 in Oregon and what kind of oil we use.
When it comes to oil changes, a little information can go a long way to helping Corvallis residents save money and extend the life of their vehicles. Stay safe, and stay on the road.
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 Corvallis 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 Corvallis 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, Corvallis 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 Corvallis 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. Oregon vehicle owners should take care to learn their vehicle's fluid requirements before topping off at home. A large part of preventive maintenance for Corvallis 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 Clayton's Auto Service in Corvallis.
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 Corvallis 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 Corvallis 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 Corvallis and very hot or freezing Oregon 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 Clayton's Auto Service 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 Clayton's Auto Service. All Corvallis 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 Corvallis drivers pay for vehicle care. But understanding what we're paying for can make us more savvy shoppers.
Today in the Clayton's Auto Service auto care blog, we're going to talk to Corvallis drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for Clayton's Auto Service customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).
In real world Corvallis driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at Clayton's Auto Service in Corvallis.
The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to follow a new, lower service interval and provide proof of oil changes in order to make a warranty claim.
So here's the bottom line for Corvallis vehicle owners: with longer oil change intervals, it's essential to follow them closely. Back in the day of 3 months or 3,000 miles (5,000 kilometers), if you went an extra month or an extra thousand miles or couple of thousand kilometers, your oil was still fresh enough that it didn't have time to build up much sludge.
But if your recommended interval is 6,500 miles (10,000 kilometers) and you go over another thousand miles or couple of thousands of kilometers, you're getting into heavy sludge territory. You absolutely need to follow mileage intervals very closely. And don't forget your severe service schedule. If you do a lot of stop and go driving in Oregon, short trips, drive in dusty or polluted Corvallis conditions, hot or cold weather or haul heavy loads, you're driving in severe service conditions. Your Clayton's Auto Service service advisor can help you determine which schedule to follow.
So check your vehicle owner's manual or talk with your Clayton's Auto Service service advisor about where and how you drive in Corvallis. Should you change your oil closer to the regular schedule, or the severe service schedule? You need to make the call.
Let me give you an example of this. Some newer vehicles have an oil change indicator. It has a sophisticated computer algorithm that tracks number of cold starts, engine temperature, RPMs, mileage and many more variables to come up with a recommendation for when to change the oil.
Depending on driving conditions, the indicator in one test vehicle came on at anywhere from 2,500 miles (4,000 km) to almost 7,000 miles (11,000 km). It's typically just over 4,000 miles (6,500 km). Sometimes our driving is easy on the vehicle – like a long road trip. Sometimes, our driving is hard on it – like towing a heavy trailer or a lot of around town driving. But, usually, it's a combination of both.
Once again, it's up to you to make the call as to when to change your oil at Clayton's Auto Service to protect your vehicle engine. Another place where Oregon drivers can go wrong is with the type of oil they use. More and more new cars are coming to Corvallis owners filled with synthetic oil. Without going into a lot of detail right now, let's just say that synthetic oil lasts longer and is very resistant to oil sludge.
But it also costs quite a bit more, so some people are tempted to use conventional oil for their oil changes. Now, it's always best to use the oil recommended by your vehicle manufacturer. Check your owner's manual see if a conventional oil alternative is allowed.
But getting back to the problem, if your vehicle came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you can't use the synthetic interval. You need to shorten it.
