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 ... read more

Every one of us has a little procrastinator inside us. Some put off getting our teeth cleaned. Others put off answering our emails. Yet others put off calling friends and family (sorry, Uncle Joe). And there are those of us who put off getting our vehicle's service done, whether it's a repair or regular maintenance. You may make the excuse that you don't have time, it can wait until tomorrow, you have other things to do. Well, there are some things you should NEVER put off when it comes to your vehicle because that procrastination could have dire consequences down the road. The biggest one is changing your oil. Yes, it's one of those things you may hear somebody nag you about, but changing your vehicle's oil regularly is probably the one thing that will do the most to keep things running smoothly… and well. It's the lubricant that keeps metal engine parts from wearing out. Oil doesn't last forever and it gets dirty, so you have to swap it out for fresh every so often. How often ... read more

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 Florissant 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 Florissant drivers, cooler operating temperatures and more engine power. Further, synthetic oil is more heat-resistant than conventional oil, and it doesn't vaporiz ... read more

The automotive professionals at garysautorepair would like to give Florissant 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 Florissant 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 Missouri ] owners rely on the advice of their friendly and knowledgeable garysautorepair 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 Florissant area.Let's start with engine oil. Florissant drivers who have been paying attention will have noticed a number of new oil weights on the Missouri scene in the last several years. Modern ... read more

Oil changes are probably the most recognized service on a vehicle. Almost all Florissant 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 Florissant 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 ... read more

Hello Missouri! 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 garysautorepair in Florissant.)Some manufacturers are extending oil ... read more

Missouri 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 Missouri 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 Missouri 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 eng ... read more

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 Florissant 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 ... read more

Today's garysautorepair post focuses on using coolant. 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 garysautorepair service advisor will know the proper coolant for your vehicle.Brake fluid is confusing for some Florissant drivers. Back when we opened garysautorepair, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Florissant 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 garysautorepair: friction modified or not. With the tremendous engineering advances in vehicle automatic transmissions, there have been several new types of fluids developed to pro ... read more

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 Florissant 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 m ... read more
