[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.] Got a case of this oil for my boat. Changed the oil for the beginning of the boating season. Seemed to have a great texture and consistency. I am please with the results and will be using this for my future needs

[This review was collected as part of a promotion.] After so many years of paying the shops to change my oil, I decided to start doing it myself. Pennzoil was my first go to since all my mechanic friends raved about it. I changed the oil as normal and decided to wait and use it for a little bit of time before writing my own review. The quality of the oil is very high. It runs cleaner and I can tell the difference in my vehicles after changing from the oils the shops use. There is an additive that is used in the oil. I did notice that if I did not shake the bottle well enough, there was additive at the bottom (you can see the difference in texture when pouring). I will never take my cars back to the shop again for an oil change and I will always use Pennzoil!

[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 used this on my car and the difference can be felt immediately. My car is showing better performance now. I love that it enhances wear protection and less oil change is required too. Awesome one for my old car with old engine.

[This review was collected as part of a promotion.] I have used different brands of oil in my vehicles over the years but the brand I keep coming back to is Pennzoil. Their full synthetic oil keeps my engine running smooth and I seem to get better fuel economy with it. I'll keep using the brand I trust.

[This review was collected as part of a promotion.] You pay so much for your car, so you definitely want to use the best products for it and this oil is definitely something your engine will thank you for. I've never had any engine issues when using this type of oil and it runs smooth.

[This review was collected as part of a promotion.] I am teaching my my some car maintenance and the reason for choosing quality products. He has an older Ranger and since we have been using the Pennzoil Full synthetic in it it has been running smoother. Giving an old truck some new life! I have been using Pennzoil for years and passing it on to a new generation!

[This review was collected as part of a promotion.] I do the oil changes for both vehicles in my household. I got this Pennzoil Full Synthetic oil for my Mini Cooper. It’s a great oil. My car has been running great since I changed the oil and put this new oil in it. This oil is easy to work with and I’ll definitely use it again when it’s time to change my car’s oil again.

[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’.
