[This review was collected as part of a promotion.] This oil is great! After switching to this oil I can tell my engine feels like it runs better and sounds better too also I am getting better MPG now. This will be my go to oil for all my cars. For the price and the benefits, this is a great deal

[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.] I have used Pennzoil Synthetic motor oi in my vehicles for years. I have had good luck with it. I drive a lot of highway miles at high speeds and I believe that Pennzoil is the best choice for high speeds and longer driving times. I run 8000 miles between changes.

[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 will start by saying that if you are looking for a detailed analysis of the oil itself, you should look for a chemist or petroleum engineer. So, I won't comment on what the oil is made of itself. Instead my review is on using the oil. I do my own oil changes and have been using Pennzoil for a while now. I really like the oil. My car has been running fine and have had no engine issues. I have nothing but a positive experience with Pennzoil. Now, if you want to decide which oil to get my honest opinion is that the brand doesn't really matter. As long as it's a major brand it will be fine. The most important thing is to make sure that you get the right oil. Check your owner's manual or pop the hood. The oil type will be written on the oil cap.

[This review was collected as part of a promotion.] What can I say but Pennzoil has been and always will be my number one choice of oil for all my vehicles! It's always kept my engines running smooth and has never let myself or anyone I know down. I will continue to use it for every vehicle I own.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is the way to go when you want high quality and a reliable product to keep your vehicle in great shape. It is the best oil out there. It is easy to use. The container itself is made where I have no problems with the oil leaking out of the bottle or anything. The oil is clean and I can tell my vehicle runs smoother. It is also great that I can go longer between oil changes with this full synthetic oil.

[This review was collected as part of a promotion.] My car uses full synthetic or semi synthetic 5w20. I have never tried pennzoil before. Generally whatever the dealership puts in my car. But so far so good with pennzoil. I have used them in the past with conventional oil but not synthetic until now. So far I am very pleased with the product and their price point.

[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.

[This review was collected as part of a promotion.] I have been a valvoline user for years but then I happened to try this Pennzoil Full Synthetic and I am I happy I did. I can just feel my Jeep running smoother. It starts with ease and runs like a champ and I will be sticking with Pennzoil Full Synthetic.
