[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 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.] Pennzoil is the best oil out there. It has yet to let me down and everytime I've tried a different oil, whatever machine I'm using the other oil on doesn't seem to last as long. Pennzoil guy for life!

[This review was collected as part of a promotion.] This is great quality oil that is perfect for my Honda Civic. This oil has my car running very smooth and seems like my engine is running quieter. It seems this oil will keep my engine running great and continue to improve the overall performance of the car.

[This review was collected as part of a promotion.] Pennzoil full synthetic oil works great for my truck. I just did an oil change with it and my motor seems to run smoothly. It is greatly priced and it can be used in my boat, vehicle and my lawnmower which is amazing. It is a trusted repeatable company that I trust. It is alway good to keep an extra in the car. I used a different brand previously but I will be sticking to Pennzoil strictly!

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic is a great product for what I do. In fact anything with the name Pennzoil on it is worth it. Keeps my engine going for a long time, great product and long lasting. Highly recommend.

[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 picked this up to save a trip to the mechanic. I love the way this oil last longer than regular oil and it’s not that much more expensive. I highly recommend it to anyone wanting to change their own oil

[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.] This full synthetic oil is just like the Review Title says, "Super slick!" My engine runs really smooth with this oil. Obvious benefits of friction reduction of engine components have resulted in a boost in fuel economy. Granted, I don't have a physical/measurement comparison, since I have not taken my engine apart to do so, I'm confident it's doing what it's supposed to do.
