Rated 4 out of 5 by jayzar Great oil
Have used this oil for years in my parents car as, as well as mine before I started to use full synthetic. It is a great oil to use. Just make sure you use the correct viscosity. As an FYI Pep Boys usually has a oil and filter sale with Castrol every other month or so.

I have been using Castrol GTX since I bought my first car in 1973. I was using the oil and I decided to do a valve job. I took the manifold off and the oil galley was spotless. I had a 1988 Chevy 3/4 ton truck and the engine lasted to 222,000 miles for a 454 big block
Chevy. I drive a 2001 Chevy Malibu with 242,000 miles on the engine with only replacing the water pump. The engine doesn't burn any oil and still gets 28 miles to the gallon of gas. Gary Ormsby and John Force were sponsored by Castrol!
