What You Should Know about Oil Changes.

Why Regular Oil Changes are Important

Your vehicle’s engine parts operate at very high speed and generate significant heat. These fast speeds and high temperatures result in tremendous friction if engine parts are not properly lubricated. Engine oil is that lubricant. With use, engine oil breaks down and collects dirt, reducing its effectiveness in keeping your engine cool and running smoothly. If your engine loses oil, or if the oil becomes dirty, your engine’s parts can “seize”, resulting in significant and expensive damage.

That means regular oil changes are the most important preventative maintenance service you can have performed on your vehicle.

Normal Versus Severe Driving

Did you know that, according to a recent survey of driving habits*, more than 92% of drivers operate their car in conditions that vehicle manufacturers classify as “severe”? Severe conditions include the type of driving experienced on short trips (stop-and-go traffic), highway traffic jams (engine idling), long trips (prolonged engine use or heavy loads), mountainous terrain, or in extreme temperatures.

How often you change your oil will vary depending on whether you drive under normal or severe conditions. So be sure to assess your driving habits and check your vehicle owner’s manual to find the manufacturer’s recommended oil change intervals for severe versus normal driving.


The Quality of the Oil Matters

All engine oils are NOT created equal. Today’s engine oils represent a broad spectrum of sophisticated blends of base oils, as well as a range of additives. Beyond lubrication, which cools the engine parts, engine oil serves to clean engine parts, inhibit corrosion, and provide sealing properties. The viscosity, or “thickness,” of the oil should vary according to a number of factors, including vehicle use and ambient temperatures. The performance of your engine oil depends on its quality.

Oilstop uses only Chevron oils, which we feel are not only the highest quality, but also the best value. In fact, Chevron oil is the basis for many competitive brands that rely on Chevron’s extensive research and quality assurance efforts.

How Oil Additives Can Improve Performance

Modern engines demand more than pure oil can provide. Oil “additives” are combined in various formulas to enhance engine oil’s performance in very specific ways. For example, some additives are designed to prevent corrosion within your engine, while others reduce friction, thereby improving fuel mileage. As with oils, additives vary in quality and their applications should be based on use.

Oilstop uses only Chevron oils with high quality additives, blended to precise specifications at the time of manufacture. Your Oilstop service advisor can recommend an additive combination that suits your particular driving habits.
