Dont use anything but Pennzoil, I drive from texas to California every 6 months and pennzoil has been my go to. Works best in my car and even helps on my gas mileage. Will never use a different brand and will pass that down to my kids. Thank you for the amazing product.

[This review was collected as part of a promotion.] I have been using Pennzoil in my rat rod for three years! I keep my foot heavy on the throttle, giving total abuse, wIting to blow its small block in order to replace it with a big block and the sucker just won't pop! I have confidence this product has ideal viscosity... The big block awaits ... Maybe I will boil the water out one day! Ha!!!

[This review was collected as part of a promotion.] Ive used pennzoil in all my cars my dad a grandpa do as well always was told to use it because it was the best I've never had any problems with my cars as far as oil goes so I will continue to buy pennzoil as long as I drive

[This review was collected as part of a promotion.] I've used Pennzoil Conventional Oil in most of my vehicles for years. No better conventional oil exists. The only vehicles that didn't use Pennzoil Conventional in my garage were the ones that I converted to full synthetic.

[This review was collected as part of a promotion.] My boyfriend is a mechanic for Trans Edge, a division of Mack Trucks. He actually does my oil changes and will only use Pennzoil! I highly trust his judgment and after an oil change my van runs GREAT!!

[This review was collected as part of a promotion.] I've been using penzoil 5w-30 ever since my first car back in high school. Didn't know much about cars back then so I actually went through a couple different brands before Pennzoil but once it made its way into my engine I was hooked. I love Pennzoil because it's not super crazy or complex, it just does what it's supposed to for my car engine & that's all I need. Trust nonother brand with my engine. Thanks! - Ron

I have used this oil for over 40 years my dad used the same oil. And I used it in my first new pick up truck and when we tore the oil pan off to check the mains and rods it looked like a brand new motor I had over 450,000 miles.The oil was changed every 2,500 miles the oil is great and I still use it in all 4 of mt trucks.

I always use this product, in everything. I also encourage others to use Pennzoil. As a teenager, i saw how QS distroys an engine, how the oil ports clog up. I use Pennzoil sea30 in my mowers and Pennzoil 10w30 in my truck. If you want your engine to last, use Pennzoil. Holly
