Super Slick at Sully’s Auto Repair in Huntington Beach: Synthetic Oil

When you get an oil change, it’s always a safe bet to just use the type of oil the auto maker 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 Huntington Beach car owners.

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 important 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 Huntington Beach motorists, cooler operating temperatures, more engine power and increased MPG.

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 Huntington Beach and very hot or freezing CA temperatures.

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

Manufacturers are aware of the advantages of synthetic oil, and many of them are using it to fill their SUVs before delivering them to be sold. Many vehicle manufacturer’s 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 SUV 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 talk to your friendly Sully’s Auto Repair service advisor. He can offer you good auto advice about oils and service intervals based on your driving habits and requirements.

Oil changes are the hallmark of vital preventive maintenance at Sully’s Auto Repair. All Huntington Beach auto owners need them. So we should get excited about a product that reduces how often we need them. Synthetic oil is more pricey, 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 in the long run. All Huntington Beach drivers pay for car care. But understanding what we’re paying for can make us more savvy shoppers.

Let’s take engine oil. Twenty or thirty years ago, there were just a handful of different weights of oil. The weight of an oil is a scientific measure of its properties, particularly its viscosity or thickness.

It was common in those days to use a lighter weight oil in the winter when it’s cold outside. That way the oil would be able to splash around inside the engine and protect the parts before it was fully warmed up. And a heavier weight oil would be used in the summer. The thicker oil wouldn’t thin out too much in the summer heat and vaporize in the engine.

Modern valve trains have become very complicated with more moving parts and small passages than ever before. The valve train is in the top of the engine, so when the car has been turned off for a while, the oil tends to run down to lower areas and the valve train parts are vulnerable at start-up, before the oil starts circulating.

So new weights of oil have been introduced to meet the engineering specifications of these newer engines.

Manufacturers are recommending specific weights of oil. The recommendation is often printed on the oil fill cap. It’s certainly in the owner’s manual. Of course, your Huntington Beach CA auto service center can look it up for you.

It’s more important than ever to have the correct weight of oil. The wrong weight could actually harm the engine.

Other fluids are also becoming more sophisticated. In the last few years new types of transmission, power brake fluid and coolant have all been introduced for some of the same reasons as for engine oil.

In addition, vehicle manufacturers are now using a wider variety of materials in these systems. Looking at the cooling system as an example, it used to be that the parts were all made out of steel or iron and the hoses were rubber. Now, some parts are plastic, aluminum or other materials.

So the anti-corrosion additives contained in the coolant, or anti-freeze, need to be different in order to protect the different materials used to make the cooling system. If you use the wrong coolant that wasn’t formulated to protect your plastic cooling system parts, they could become corroded and fail. And if you’re using the wrong coolant, your cooling system won’t be covered under warrantee. So it’s important to use the right coolant and to not mix different types.

Your owner’s manual or your Huntington Beach CA service advisor at Sully’s Auto Repair can make sure you’re using the right type. You may have heard of universal coolant. Universal, or global, coolant can be added to other types without harmful reactions. That’s OK for an emergency top off, but following your manufacturer’s recommendation for your SUV or other auto type is always a safe bet.

In the area of brake fluid, there are a couple of new formulations. It’s important to remember that the new ones aren’t better than the old ones. They’re just different formulations for different vehicles. So if your vehicle calls for DOT 3, using DOT 4 or DOT 5 is not an upgrade. Use the recommended formula.

There are fluid formulations for vehicles with higher mileage. These are special engine oil, transmission fluid, and so on that contain additives to condition and restore seals and gaskets in older engines.

They’re fine to use as long as they’re a variant of the proper fluid. In other words you can use a high mileage engine oil as long as it’s also the correct weight recommended by the manufacturer. Same goes for transmission fluid; as long as it’s the right type for your transmission.

The Sully’s Auto Repair Guide to Proper Fluids for Your Vehicle

The automotive professionals at Sully’s Auto Repair would like to give Huntington Beach auto owners an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday – and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The Buena Park do-it-yourselfer has to be pretty careful so that they do not actually harm their SUV with the wrong type of fluid. That is why so many CA car owners rely on the advice of their friendly Sully’s Auto Repair tech to not only get the correct family of fluids, but to suggest the formulation that is best for their car and their driving habits in the Huntington Beach area.

Let’s start with engine oil. La Palma motorists who have been paying attention, will have noticed a number of new oil weights on the CA 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 automobile manufacturers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your Huntington Beach service center will know what weight your automobile manufacturer recommends – and it’s important to follow those recommendations. Your tech at Sully’s Auto Repair 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, manufacturers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that car makers are using to build the cooling system. Using the wrong type of coolant in your SUV or other vehicle can actually void your warranty, so it’s vital to get that right.

Transmission fluid is becoming specialized for Huntington Beach 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 Huntington Beach house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids CA car owners need will grow. And, some of the formulations will cost a little more for Huntington Beach drivers. Fortunately, Sully’s Auto Repair will continue to update their training to keep pace with technology so that you’ll get the right fluids your car needs. It’s all part of the commitment we make to your driving peace of mind.
