[This review was collected as part of a promotion.] Pennzoil Full Synthetic Motor Oil is good quality motor oil that helps keep my engine running smooth. It is better than conventional oil and will allow for fewer oil changes in the future so that is a plus.

[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.] This came at a perfect time as my car needed an oil change. I usually go for Pennzoil brand oil because I’ve never had any issues and it is a trustworthy brand. The price is right and is good quality oil.

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic oil was super easy to use it made for great performance in my vehicle. It was easy to distribute with the shape of the bottle. I absolutely stand behind this brand. I would not turn to anything else.

[This review was collected as part of a promotion.] Used this for oil changes in all my equipment, feel totally confident in the Pennzoil brand, and I prefer Synthetic over traditional oil. The case was just the right amount for all my machines with a spare bottle left over.

[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 often find myself helping family out with oil changes at my place. I always like to have some on hand and went for this. Absolutely great quality for the price. I now keep this available in my garage all the Time. I do recommend

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. This is another great great product that they make!

[This review was collected as part of a promotion.] This oil is great! After switching to this oil I can tell my engine feels like it runs better and sounds better too also I am getting better MPG now. This will be my go to oil for all my cars. For the price and the benefits, this is a great deal
