[This review was collected as part of a promotion.] This is great oil, definitely prefer this over any thing else on the market. Super clean, engine has been running amazing. Will continue to use this synthetic oil for many more years to come. I absolutely recommend this product if you're looking to switch over from any other kind, especially if you're getting over that high mile threshold.

[This review was collected as part of a promotion.] We all know Pennzoil stands by their name. I will not go with any other brand. The price is more than worth it. I feel like If I can trust this brand so can everyone else. Please spend the extra amount on Pennzoil it is more than worth it.

[This review was collected as part of a promotion.] Excellent performance and protection. One of the best in the market, have observed that slight increase in mileage and the car runs smoother. Also last quite longer before oil changes that the other brands. Can't go wrong with this one

[This review was collected as part of a promotion.] I used the Pennzoil Full Synthetic 5W-30 in my Chevrolet 6.0 after verifying it is Dexos approved. My mechanic commented that it is excellent oil. It functions well, holds good oil pressure and the engine ran cool and quiet.

[This review was collected as part of a promotion.] I changed my oil with this Pennzoil Full Synthetic oil and will update this review in two and a half months after I complete another oil change. I put my old oil in an airtight container and will compare the Pennzoil to that once I do my next oil change. I have no other way of knowing how well the Pennzoil works other than to compare it to the brand I regularly use. I’ll be back! My wife says I can’t update reviews, so I will complete another review after my next oil change.

[This review was collected as part of a promotion.] I decided to spend the money on full synthetic oil and save money on the labor by doing the oil change myself. I had been taking it to the shop. Now that my son is old enough ,and wants to work on cars, I thought this would be a great start. I can only assume there are no problems since there are no problems. Right? Many miles to go, and then we will do it again.

[This review was collected as part of a promotion.] I did an at home oil change on my wife's RAV - 4 over the weekend. I tried the Pennzoil Full Synthetic 5W - 20 over my other synthetic choice. I honestly prefer Pennzoil, the weight, color and lack of oil smell was nice so my wife didn't complain. She just drives the car so hasn't noticed any change in the ride or power.

[This review was collected as part of a promotion.] Pennzoil full synthetic oil is top quality. took the oil to my mechanic to do an oil change for me. He said that I got the "right stuff" and that Pennzoil is what he recommends. My car is running great and I am very happy with everything.
