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

I have been using this oil since 1984, I blew up my engine on my 1983 monte carlo when i removed the block there was a thick layer of goo all inside, At the time I was using quaker state I switched oils and have never had a issue with my engines I have owned 5 cars since then all with well over 150000 miles put on them by me not one issue. I used it in 4, 6, and 8 cylinder engines I dont believe i will ever use another type of oil. tried and tested by me!

[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.] Multiple cars and suvs over the years and I've always trusted Pennzoil. It's always kept them running smoothly until my next oil change. It's a tradition passed down from my father when changing the oil in all of his vehicles.

[This review was collected as part of a promotion.] I've been using Penzoil for the past 40+ years. The engines were 40hp Volkswagens, 12hp snow blower, through 700hp drag racing Ford 502 engines. Never any lube problems. I will continue using Penzoil in all of my vehicles/engines. My 3 kids also use Penzoil in all of their vehicles.

[This review was collected as part of a promotion.] I have used Pennzoil since I started driving back in the late 60 . It's never let me down . I have 5 cars two with over 100k and one with 250k the other two have lower miles on them but I've never had one failure from this oil . I highly recommend it !

[This review was collected as part of a promotion.] When I used to change my own oil at home, I used this brand. With the car having free oil changes for life, I'm sure they use something else,Too bad really. I always liked watching their ads on tv back in the 70's and 80;s

[This review was collected as part of a promotion.] I use all your oils in all my equipment never had had any problems... My 87 mustang my truck my wife's car.. All my lawn equipment.. And on and on.. Keep up the good work people ;) merry Christmas!!!

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 use this oil in my 97 5.9 Dakota since it was rebuilt by me. I have 247k on the truck that was mostly done by a 5.2 motor that at one time had nitrous on it. It still runs and I still have it. I got the truck at around 100 miles and it was abused and nasty on the inside with no air cleaner or pcv valve. This oil cleaned it up considerabley after 3 oil changes and correcting the filters. I have always used pennzoil in all of my vehicles over the year's and have had no failures.
