[This review was collected as part of a promotion.] I've used Pennzoil for years in my race car and personal vehicles. I have never had any problems related to the oil. It keeps everything clean and well lubed!

[This review was collected as part of a promotion.] Have used Pennzoil oil since I was a kid on my bicycles and in all my vehicles we owned a full service Pennzoil station for over 30+ year's and that's the only oil I will use period!

[This review was collected as part of a promotion.] I only buy Pennzoil Gold when it comes to servicing my car and getting the most mileageand best performance I can! Thank you all at Pennzoil so much!

Just had my oil changed before I made a 1500+ mile journey and of course we used Pennzoil!! The mechanic gave me a really cool Pennzoil sticker too! Everyone in my fb Joey Logano group wants the sticker now!

My 1988 Mercury Grand Marquis GS is extremely picky when it comes to oil. If I get anything other than Pennzoil, it runs rough and fuel economy goes down. Pennzoil is cheap but extremely great, especially for older engines.

This is the only oil I trust to protect my engine in my Mustang GT. It took me too long to find my perfect car so I don't take any chances with any other oil.

[This review was collected as part of a promotion.] I have used this oil in my truck for quite some time now and it is great.I have never had a problem with pennzoil and will continue to use it.

[This review was collected as part of a promotion.] It works and that's what counts, Penzoil, for all my vehicles needs. Keeps everything running smoothly.

My dad used conventional pennzoil in three of our cars when I was growing up. All the cars lasted over 200,000 miles and one of them 280,000 miles. I like pennzoil.

I drove a 1998 Ford Expedition until I sold it in 2015. Always used pennzoil and never had any major engine issues. Sold it with 150000 miles and it still ran great.
