oil-changeThere are many choices when it comes to picking the appropriate oil for your car’s engine.

Viscosity is the most important property of a lubricant. Understanding viscosity promotes the ability to reduce wear, improve fuel economy and make more horsepower.

Viscosity (a fluid’s resistance to flow) is rated at 0° F (represented by the number preceding the “W” [for Winter]) and at 212° F (represented by the second number in the viscosity designation). So 10W-30 oil has less viscosity when cold and hot than does 20W-50. Motor oil thins as it heats and thickens as it cools.

Remember that using oil with a viscosity that is too high can result in excessive oil temperature and increased drag. Using an oil with a low viscosity can lead to excessive metal to metal contact between moving parts. Using the correct viscosity oil eases starting, reduces friction and slows wear.

It is important that you pick the viscosity (thickness) that’s suitable for the temperatures your vehicle normally operates in (check your owners manual), and you’re done. Well, not quite. There’s a whole lot more to the story than that.

Armed with knowledge of viscosity grades, you can now select the right one. In return, you will prevent wear, improve fuel economy and make more horsepower.

Is oil really the lifeblood of an engine?

That’s a long-popular analogy, but it’s really not an accurate description. Blood carries nutrients to cells, but it’s air that carries fuel—the “nutrition”—for an engine. However, without oil to lubricate and cool moving parts, keep them clean and help to seal the pistons in the cylinders, the engine would run for only a matter of seconds, then sieze. So, yes, oil is important.

Oil is so important that we want no less than the best the engine can get—for a good low price, of course. Now, what if you could custom-blend the oil so it had exactly the characteristics you believe that your vehicle needs for the type of driving you do?

Recommended Oil Types 

The weight or viscosity of oil recommended for your vehicle should be located in your owner’s manual, or you can just ask one of our ASE certified Technicians. Changing your oil and filter according to this schedule can save you big $$ and reduce the need for repairs down the road.

After determining the correct viscosity, the next choice in motor oil is what type? Higher mileage blends can benefit engines over 75K miles. Synthetic blends and full synthetics can bring additional protection and often flow more easily during severe cold than conventional oils.

If you are not sure, just ask! We have trained professionals at all of our 4 locations in the Reno and Sparks area. We are more than happy to assist you, for appointments or walk-ups.

Our fully qualified ASE Certified Technicians will do everything possible to keep your vehicle running safely and efficiently.
