[This review was collected as part of a promotion.] Ok I've been using Pennzoil for a long time now. Specially the full synthetic. I change my oil between 5k and 7k miles and I've got over 200k miles on the car. I feel like the oil is one of the reasons my car still runs strong.

[This review was collected as part of a promotion.] I switched up my oil in my ride when I had my oil change about three weeks ago my car has been running smoothly since I half to say that Pennzoil Full Synthetic oil is the way to go I am going to be honest get yall some

[This review was collected as part of a promotion.] I received this oil last month . I really love brand of oil. I love it’s synthetic which I use in all my vehicles since they all have high milage. I really like this brand and will be using this from now on’.

[This review was collected as part of a promotion.] After replacing the engine oil in both my generator and lawnmower with this brand of oil the engine sounded smooth and run like a charm and this was the first time for me of ever using this brand of oil and in my opinion this engine oil is of the greatest quality of oil on the market.

[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.] 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.

[This review was collected as part of a promotion.] My car only takes full synthetic oil so this pennzoil is a great oil for my car. The bottles were easy to open and easy to pour. I am sure I will get the full mileage out of the oil. The bottles can be recycled which is a big plus.

[This review was collected as part of a promotion.] It is very difficult for the average person to evaluate oil. I do not know the inner workings of engines. But what I can say is that my experience with this Pennzoil Full Synthentic comes with no compaints whatsoever. The bottles are easy to handle, I'll be using this oil for my next oil changes for sure. My car is 11 years old and the engine has been a bit shaky lately, but I used this oil to top off and it's been running smoothly ever since.

[This review was collected as part of a promotion.] I wanted to start using a full synthetic oil for my vehicles. I wanted a name brand that I could trust. I have used Pennzoil for 45 years. I have used it in every vehicle that I have owned. Changing to synthetic oil for me with the amount of travel I do now yearly makes sense. Going longer between oil changes and the heat protection it will provide are the key reason for the change. Convenient six pack is right for me.

[This review was collected as part of a promotion.] Recently did an oil change and my thought always was that all oils are the same. I was wrong. My car was actually quieter and burned less of the Pennzoil than my previous brand. Seems to last longer also as I checked my oil and it was not black or dark as usual. Very pleased and will be using Pennzoil in all my cars for now on
