I purchased a new Honda Civic in 1994, I would changed the oil every 3,000-5,000 miles. Advance 23 yrs later and 385,000 miles later I still have the same car, same engine, and it does not burn oil

I use 5w20 non synthetic for years now on my Econoline 350 5.4 and keeps the motor going strong, I do wish they would make an 8 Qt jug though because it gets very expensive even though I will not use any other type of oil !!!

My Mom used this oil for yrs and yrs in her old Crown Vic 2 door, and thats all she would use The car life was extended forever she swore I believe her!!!

My engine was burning oil like crazy using synthetic and when I switched to pennzoil conventional I never burned oil again. I'm staying with pennzoil from now on. Best oil

Good price and quick shipping and good packaging.

I've always used Pennzoil oil in my car and it has always been a good oil.

Never any issues with this product

A good oil that has always worked well in our truck !

I've always been a Pennzoil user

My truck is 16 yrs old with 158,000 miles. I have been using Pennzoil since my first oil change. The oil still looks clean in the engine today. The Mechanic who did my alignment said he wa impressed with the engine performance. Asked if I wanted to sell my truck to ask him first.
