Oil, What’s It Good For? Protecting Your Engine

Conventional or Synthetic?

10W30 or 0W20?

3,000 miles or 5 months?

THE MOST FUNDAMENTAL THING you can do to care for your car or truck is to change the oil and filter – and do it regularly. Engine oil serves 2 simple purposes:

  • Lubricate the internal moving parts of your engine

  • Carry away debris to be collected in the filter

It’s equally important to heed the manufacturer’s oil specification. It’s not ‘10W30 fits all’ any longer. A large number of vehicles call for 5W30 and even others 0W20. In fact, there are bottles of engine oil on parts house shelves that are entirely inappropriate for any car or truck engine built after 1979. It pays to be certain that the oil that goes in to your engine is exactly what the engineers who designed it call for.

All you really need to know is this: The internal clearances of engines are sized to accommodate particular grades. A flow factor of 10 is far thicker than a flow factor of zero. So, it reasons that 10 would be too thick to properly lubricate an engine that called for 0. Sort of like using molasses where water was called for.

The best way to be sure you’re protecting your engine is to rely on professional service providers, like us! We always check the manufacturer’s specification for motor oil weight and volume before servicing your car or truck. On any given day we have 10 to 15 different grades of oil on hand. If we don’t have it on the shelf, we’ll get it here fast– just for you!

Change your oil and filter. Better yet, let us do it for you.
