[This review was collected as part of a promotion.] I've had a Chevt truck with a leak on it and the oil pressure gauge went to ( 0 ) I had to drive it 5 miles like that I went slow not hard driving got jome and put oil in it (Pennzoil the only kind I use ) and drove it for an additional 2years . Tranny went out on it.

I used 10-30 w.in All Vehicles that I've Owned. I Had a Jeep Cherokee with a 4 liter inline6 cylinder in it and Put 335.000 miles on it before it got in a Crash in a IceStorm.A Freind Bought the Motor and Put it in His Jeep .He has put over100.000 more miles on it and last check she is still going. And We Have Been Rough on it at Times. Bottom Line Best Oil I've Ever Used.

[This review was collected as part of a promotion.] I have always used Pennzoil in my Ford Mavericks, and still do! I trust Pennzoil to give my engine the protection it needs, I drive my Maverick hard, I need an oil that works hard to protect my engine.

[This review was collected as part of a promotion.] I've been a long time user of Pennzoil with 10 vehicles and almost 2 million miles I never had any real problems with any of them and I give the credit to Pennzoil and changing the oil every 3,000 miles in the past and every 4,000 miles on my jeep now. I will never use anything other than Pennzoil

I just got my first car and my dad told me "I told your brother and sister what i'am about to tell you, you ONLY use Pennzoil for your car" he says he believe it's the only brand that will work is Pennzoil I've never seen him use anything eels our garage is has all Pennzoil bottles! and I believe him because it's the only thing I use. I know my dad could give a more detailed review on your amazing product, but I'm hoping to surprise the family! Best product out there! My whole family is TEAM JOEY LOGANO

I was literally raised to use Pennzoil. My dad and uncles would always talk about fixing cars & they they never even said "motor oil" they always said "Pennzoil" and our garage always had the yellow quart bottles around. I still use Pennzoil it to this day & it's always worked well with my vehicles. The yellow bottle is Iconic! I miss seeing that Pennzoil logo on Michael Waltrips car growing up.

[This review was collected as part of a promotion.] My grandfather would only use Pennzoil and he never had a problem ever with Pennzoil. I took his advise when he told me Pennzoil was the best,I,m almost 40 years old and I have never had a problem with it and I own quite a collection of cars trucks motorcycle atvs 4 drag cars and heavy equipment 6 lawn mowers and generators.and I only trust 1 oil. 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.] 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 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 !
