[This review was collected as part of a promotion.] Pennzoil Full Synthetic is all I use on my vehicles. I have a Jeep and of course I change my own oil. I love how easy this is to use and the quality it provides to my vehicle. My Jeep is running smoothly.

[This review was collected as part of a promotion.] I use and will continue to use full synthetic in all of my had run engines. Those are all my small engines and my SUV with the turbo on it. Anything that is labeled eco-boost or has a "t" in the model name has a turbo in it and probably already calls for it. Pennzoil has never let me down and I'll continue to use it.

[This review was collected as part of a promotion.] Time and time again, this oil impresses. It holds its lubricating capacity better then most whilst being very affordable. I have worked on cars for 30 years and this is my go to oil. What more could one desire..

[This review was collected as part of a promotion.] I used the Pennzoil Full Synthetic 5W-30 in my Chevrolet 6.0 after verifying it is Dexos approved. My mechanic commented that it is excellent oil. It functions well, holds good oil pressure and the engine ran cool and quiet.

[This review was collected as part of a promotion.] I have been using the Pennzoil full synthetic for my car and it is the absolute best It gives my car full protection for those critical engines’ parts. With Pennzoil full synthetic, you will need fewer oil changes that a conventional motor oil. It comes with enhanced wear protection for high and low temperate. I have noticed my engines runs more smoothly and the car feels like and drive new. The Pennzoil helps present sludge and deposit build up. I use this oil up to 10k miles and then do another change. I trust a name like Pennzoil for my engine and I never do an oil change without it.

[This review was collected as part of a promotion.] I recently purchased some Pennzoil Full Synthetic Motor Oil. This oil is very reliable to use since it is manufactured by Pennzoil. This company has been around for many years, I know because I used it when I was a kid and that's been a long time ago. The use of this oil allows you to go many more miles between oil changes. The full synthetic oil is manufactured from natural gas which is very good for emissions and is readily available. It meets all gasoline engine manufacture's requirements. I thoroughly recommend this motor oil.

[This review was collected as part of a promotion.] I had an oil change using the Pennzoil full synthetic oil and my car seems to run very well. The 5w -20 oil is working to keep my engine clean and protect against friction. I had my mechanic use it and my car runs great.

[This review was collected as part of a promotion.] So I changed my oil at jiffy lube and always used the synthetic and I never knew how easy it was to change your own oil. This oil works great and I would recommend to use. My car has a 150k miles on it and it ran smooth

[This review was collected as part of a promotion.] I really like Pennzoil Full Synthetic motor oil. Pennzoil has been around for over 100 years so they know what they are doing as far as motor lubrication is concerned. This oil should be great in my lawn equipment and generators.

[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.
