I do a lot of oil changes myself, when I don't have time I have my mechanic do it for me. He recommended this oil for my car because it has a lot of miles. I am happy with it.

[This review was collected as part of a promotion.] My hubby only uses Pennzoil to maintain his high mileage truck. We depend on our truck as we pull a fifth wheel across Michigan and need a good running truck. Sweepstakes entry

[This review was collected as part of a promotion.] This is all I buy used cheap oil one time and threw a rod before my next oil change wont ever use another

[This review was collected as part of a promotion.] I don't know what it is about this stuff but it works great in my truck with 240,000miles. I find it reasonably priced and can find it anywhere.

[This review was collected as part of a promotion.] I use this in my fleet of service vans. They all have over 200,000 miles on them. This stuff works wonderful in them. I keep great oil pressure and engines are clean. Love this stuff.

[This review was collected as part of a promotion.] Helped bring power back in my plow truck which was loosing strength and performance which was so much needed to do the job !

I bought a 99 Corolla brand new original owner used nothing but Pennzoil. Now 19 years later and 370,000 later , well what can you say. No leaks and doesn't burn any oil. High mileage is the way to go.

I was told by my father as a small child you'll never get any better then pennzoil and still to this day when I change my oil it's the oil I grab first thing I honistly believe it's the best oil out there.
