I have been using this oil for years there is no exception.

Been using Pennzoil for years and my car runs great

I used mobile 1 before, after switching to Pennzoil, I've never been happier

A good value for a very good quality oil. I often use in my car

I have a 1984 Monte Carlo and the lady before me use Pennzoil and so do I ! The only oil I use !

I have used this since 2008. Best conventional out there.

Have been using for some time in several of our vehicles. Great product and great value

For a brand name oil, price is lower than other leading brands. It's a plus since its pennzoil.

Change oil every three thousand miles with usi g it

we always use this and it has never let us down. so glad we bought it.
