[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.] I prefer using a full synthetic oil in my cars. This Pennzoil 5W-30 has worked well and I have had no issues with it. The bigger jugs make it easy to pour in and cuts down on plastic with the smaller bottles. I recommend this full synthetic oil.

[This review was collected as part of a promotion.] I got this Pennzoil full synthetic to use in my f150. I usually take it to the dealer and they use a synthetic blend. Well my warranty is up so I figured I'll start changing my own oil and at the same time this will give me a chance to keep an eye on what's going on under the truck. (leaks and such) I've used pennzoil in the past on other vehicles with good results so this was pretty much a no brainer. Time will tell but with a company that's been around this long they must be doing something right!

[This review was collected as part of a promotion.] I changed my oil 11 days ago and replaced with the Penzoil synthetic. I have always used synthetic as my car requires it. Traditionally, I would use the manufacture brand. I did not notice any difference from this brand to the previous. Unfortunately , I am writing this review 11 days after trying. Ideally, if I were able to wait the 5000 miles and then my review would be more comprehensive and complete. So far the oil seems the same as previous .

[This review was collected as part of a promotion.] I've used Pennzoil Platinum or Pennzoil Ultra in my 3.6L 2015 Jeep Grand Cherokee & my wife's 2017 Ford Edge since day one. Both vehicles are now over 90,000 miles and run great. The biggest difference I've noticed between this and oils I've used in the past (in other vehicles) is with cold weather starting. With Pennzoil synthetics both of our vehicles start without hesitation or that dry/clunky noise on winter mornings.

[This review was collected as part of a promotion.] This oil is the best you can get, at least one that is affordable. It cleans, protects, and lubricates very well. Shake the oil before adding to get all the detergent out, because it may have settled. Pennzoil offsets 100% of the carbon emissions from creating the oil.

[This review was collected as part of a promotion.] Pennzoil is by far the best engine oil I’ve used so far. I feel much better putting this oil in my car. I’ve gotten great performance from my car. The engine sounds great and runs smoothly. This is a great oil for my car.

[This review was collected as part of a promotion.] It's a great full synthetic oil from a brand you can trust. So, the results are perfect, as expected! Great packaging for the shipping, impressive results! This oil will keep my car's engine running nice and smooth for the years to come.

[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.] Such a great product from a name you can trust. Now it may cost a little more than your standard oil but the protection it provides for what most people refer to as their prized possession can't be measured in dollars. You just can't get by anymore with just any oil, not with today's cars. The synthetic oil adheres better than conventional oil and in some makes and models its required. So if you're like me you'll stick with a quality product from a name you can trust.
