[This review was collected as part of a promotion.] What can I say but Pennzoil has been and always will be my number one choice of oil for all my vehicles! It's always kept my engines running smooth and has never let myself or anyone I know down. I will continue to use it for every vehicle I own.

[This review was collected as part of a promotion.] I had an oil change using the Pennzoil full synthetic oil and my car seems to run very well. The 5w -20 oil is working to keep my engine clean and protect against friction. I had my mechanic use it and my car runs great.

[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.] As usual great product. I’ve been using Pennzoil for years and this is my first time trying the full synthetic I was hesitant at first because I didn’t know much about synthetic oil. After some research at homework I found out the Pennzoil is one of the top oils in full synthetic. I am completely impressed and amazed by the quality that Pennzoil is presented in this product I highly recommend anyone looking for a full synthetic oil.

[This review was collected as part of a promotion.] My vehicle takes synthetic oil but it's a big cost to get it changed so I invested into doing it myself. Normally I would get my oil change done at places, with a high cost, and a lower level oil but today...today! I will commit to changing it myself. No more stripped out bolts, no more leaks, today I get to batten down all my hatches and create an oil change I know won't go wrong.

[This review was collected as part of a promotion.] Since 1913 Pennzoil has been a true and trusted product for autos. And they've continued caring for our cars and trucks by coming up with a full synthetic oil that not only better protects our engines, it also outlasts regular oil allowing more miles between oil changes. It's a great product for my car which has over 200,000 miles, and is still going strong.

[This review was collected as part of a promotion.] Works great had worked great so far for my vehicle I have not had any problems that I can tell It has worked great and I would recommend to anyone that is doing a home oil change and needs a good brand

[This review was collected as part of a promotion.] I have used Pennzoil Synthetic motor oi in my vehicles for years. I have had good luck with it. I drive a lot of highway miles at high speeds and I believe that Pennzoil is the best choice for high speeds and longer driving times. I run 8000 miles between changes.

[This review was collected as part of a promotion.] I have always used Pennzoil products in all of my engines. When I recently purchased a newer car, I had the chance to run the full synthetic. Now I have changed over to the full synthetic in every application possible. This stuff is the good stuff! Great bottles with easy to open/pour packaging.

[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.
