[This review was collected as part of a promotion.] Pennzoil Full Synthetic is their top of the line oil. I have used it for years and it keeps the engine clean and running great. Meets Chrysler and Ford specs along with many others. 5000 miles between oil changes is no issue!

[This review was collected as part of a promotion.] I regard myself as someone who is not a rookie/novice do it yourself but not a expert. I'm always learning things and working on my own cars is 1 thing I love to do. I've used this brand in the past when going to a shop but now I do it myself and it has never gave me any problems!

[This review was collected as part of a promotion.] This is the best oil that I have used. It is long lasting and my vehicles run great with it. I will not use anything else in my vehicles and I think that their life is extended from using this. I wish I would have switched earlier... Well worth the money.

[This review was collected as part of a promotion.] I was sent a case of six bottles of Penzoil Full Synthetic oil to try. First off I was shocked that I ended up getting a case of this oil. This oil works great for my car. Sometimes I tend to buy cheaper oil and I think that that oil does not work as well. Using Penzoil I know that it is better for my car and lasts longer. Having six separate bottles is more convenient than having to store a big bottle. This oil has just the right amount of thickness, meaning its not watery like some other brands.

[This review was collected as part of a promotion.] I received this a while ago and just did my oil change yesterday. Oil was clean and went in steady. I applied the new filter and only time will tell how my engine runs. So far it seems do be running great!

[This review was collected as part of a promotion.] I started using pennzoils full synthetic oil on both my trucks about a year ago. Long lasting...I typically go about 7,500 miles between oil changes and the oil still looks good when I drain it. Could probably go another 7,500. Not all oils are of the highest quality as pennzoil

[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.
