[This review was collected as part of a promotion.] I got this to try in a vehicle we have with high milage. We have only used synthetic oil in our vehicles for about the last 25 years. This Penzoil product seems to perform well compared to my regular brand. Even though it's the summer and it has not been in the vehicle very long it does seem to be doing an adequate job. I would like to reevaluate in the winter and at the end of this oil's life cycle, but not sure I know how to reaccess the review site.

[This review was collected as part of a promotion.] Recently did an oil change and my thought always was that all oils are the same. I was wrong. My car was actually quieter and burned less of the Pennzoil than my previous brand. Seems to last longer also as I checked my oil and it was not black or dark as usual. Very pleased and will be using Pennzoil in all my cars for now on

[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.] Pennzoil is a brand that I have always admired. I use it with the confidence because quality is in it's name. There are many brands to chose from but you will never go wrong using Pennzoil Synthetic. It's a name that's been around a long time and you can trust that.

[This review was collected as part of a promotion.] I've been changing my own oil for a lot of years now and have always trusted Pennzoil. I have tried other brands before but keep coming back to Pennzoil so far I've been very pleased with Pennzoil full synthetic as always great quality

[This review was collected as part of a promotion.] We use this oil in our Subaru Forrester 2010, it really helps the engine run smoothly. Our car has over 125K so it does burn some oil, and it is always nice to have this on hand to top off when needed.

[This review was collected as part of a promotion.] I've relied on Pennzoil Synthetic for years in my vehicles, lawn tractor, and utv. I've never had an issue, oil filters stay clean longer, and engines run smooth. It's easy to pour and my funnel filter is always clean. With regular oil changes, both my vehicles and other equipment are well maintained and last longer - my goal.

[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.] The Penzoil Full Synthetic Oil OW-20 is for people changing from typical oil to full synthetic engine oil for a smooth switch. I found this oil to be very effective and it really helped my car to run super smooth and provided the most efficient oil crossover possible. This Pennzoil product is for gasoline engines only and provides 40% better performance than conventional motor oil. It comes in a 1 qt container with a twist off top for easy pouring and even has a clear vertical line for precise measuring. I have found confidence in this product and brand and I will definitely be using it in the future.

[This review was collected as part of a promotion.] I have never tried the synthetic oil previous to this. I heard rumors to stay away from synthetics in the past. My son in law is a farmer,( they use a lot ) and he is the one that convinced me to try it. I have it in my riding mower and truck. I guess I had some bad information.
