[This review was collected as part of a promotion.] I love Pennzoil. I like the fact that it is made well without contaminants in the oil like regular base stock mineral oil. Works great and all the applications that I used it in for my jeep wrangler and suabru. I've found that cars I've used other oil on have had engine troubles, while I can prove a correlation I do believe this to be related.

[This review was collected as part of a promotion.] After so many years of paying the shops to change my oil, I decided to start doing it myself. Pennzoil was my first go to since all my mechanic friends raved about it. I changed the oil as normal and decided to wait and use it for a little bit of time before writing my own review. The quality of the oil is very high. It runs cleaner and I can tell the difference in my vehicles after changing from the oils the shops use. There is an additive that is used in the oil. I did notice that if I did not shake the bottle well enough, there was additive at the bottom (you can see the difference in texture when pouring). I will never take my cars back to the shop again for an oil change and I will always use Pennzoil!

[This review was collected as part of a promotion.] I do the oil changes for both vehicles in my household. I got this Pennzoil Full Synthetic oil for my Mini Cooper. It’s a great oil. My car has been running great since I changed the oil and put this new oil in it. This oil is easy to work with and I’ll definitely use it again when it’s time to change my car’s oil again.

[This review was collected as part of a promotion.] This is a very good oil that produces a very good used oil analysis reports. It appears to do a very good job of keeping the internal clean, And although not designed as a long drain interval oil you can’t push the limit. For instance I’ve went 15,000 miles with a turbo.

[This review was collected as part of a promotion.] I have been using Pennzoil for as long as I have been driving. I have never had any issues that were oil based. It works great, and has a great legacy behind it. I'll continue using Pennzoil in all my cars going forward.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic 5w30 case of 6 is very convenient and a bit cheaper to buy than buying 6 individual. We have several vehicles so need to buy a lot of oil. Best oil we've bought in a while its quality is superb

[This review was collected as part of a promotion.] I purchased this pennzoil motor oil due to needing an oil change in my truck. I always use pennzoil full synthetic motor oil. This is great oil and I would definitely recommend this oil for anyone needing oil.

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. It is the only oil that goes into them. The full synthetic is absolutely the best, I will continue to use this going forward. If you're looking for a full synthetic oil, this is it.

[This review was collected as part of a promotion.] I picked this up to save a trip to the mechanic. I love the way this oil last longer than regular oil and it’s not that much more expensive. I highly recommend it to anyone wanting to change their own oil

[This review was collected as part of a promotion.] I've been using Pennzoil oil for a very long time. And now that our Honda is getting a bit up there in age and wear, I decided I wanted to transition to synthetic oil. Since I e made the transition, I've noticed a slight increase in fuel efficiency and how the engine runs. I'm excited to see how well it performs as the year goes on, but I know I can always trust Pennzoil, so I'm expecting solid results!
