The “W” in 10W-30 oils stands for
“weight” -- the most
important thing to know about oil is viscosity Oil is measured in single grade or
multi-grade, and the oil is timed in seconds.
Example: SAE 30 means the oil takes approximately
30 seconds to flow through the tubes.

When engine oil turns dark, it’s
dirty and should be changed
– dark oil is dirty oil, which is false! Most modern oil disperses tiny
particles called detergent additives. That’s why the oil appears darker. This in
no way impedes the oil from performing its normal functions of lubricating and
protecting the engine.

You should change your oil every
3,000 miles – modern
detergents oils viscosities are better auto engineered to allow cars to travel
7,500 miles between oil changes.
Consumer Report has debunked this myth and driving 7,500 miles between
oil changes shouldn’t harm your vehicle in any way.
