I've been using pennzoil since I had my first car a 1974 ford ltd in 1984 when I was in high school....

I use this in my jeep and it really helps to keep the engine parts running in good condition and helps the gas milage increase

Have been using Pennzoil in everything from my car, truck, RV, lawnmowers, etc for over 40 years and never have had a problem!!
