[This review was collected as part of a promotion.] I've been using Pennzoil since I got my first car at 16. I'm 67 now and still using it for all my oil changes. Always satisfied and engines are always clean . I have 165,000 on my GMC Denali and she's still running smooth.

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.] My grandfather would only use Pennzoil and he never had a problem ever with Pennzoil.

And I wanna take this chance to THANK EVERYONE AT PENNZOIL for all your hard work and AWESOME PRODUCTS. And may you all have a very MERRY CHRISTMAS and GOD BLESS YOU ALL!!!

[This review was collected as part of a promotion.] I have a vehicle that went over 300,000 miles on conventional 10W40 Pennzoil before needing internal repair (not lubrication related). The crankshaft measured out at near perfect factory dimensions, and there was virtually no internal dirtiness. Saw similar results to this in several other engines at tear down after anywhere from 100,000 to over 400,000. No other oil has proven as reliable.

been using Pennzoil for years since i've started driving went to the store and bought my first oil didnt know much about oil so i bought the yellow bottle cause it look cool and little did i know i would be using Pennzoil in all the cars and pickup i own

[This review was collected as part of a promotion.] I've been using Pennzoil for quite a few years. I'm very impressed how it stays clean for many miles. But at the end of the chance period it cleans all the impurities out. I use this in my 06 Dodge Ram, 74 Plymouth Duster, 92 Z34 Lumina, 98 Durango mud toy, my fiance's uses platinum synthetic in her 08 Hemi Charger. Like I said. This is the best oil around. Weather it's for a classic, a play toy, daily driver, or high HP applications.

This oil has been used in my family for as long as i can remember it works great the engine always runs very smooth it always has great pressure and every tie i do an oil change on my truck the engine is very clean PENZOIL #1 please tell Joey Logano i said Hi from Jonathan his number 1 fan

[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
