[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.] This is great oil that I used in my high mileage car. It really seemed to help and quiet the engine. It also seemed like I got better gas mileage after my oil change. I have used many different oil brands and this is one that you can trust will do a great job.

[This review was collected as part of a promotion.] Have been running this in my 2014 Wrangler (145k+ miles) since we reached 75k+ and couldn't be happier. Long lifespan and has been great in preventing other engine issues and usually get at least 4,000 miles per oil change

[This review was collected as part of a promotion.] I use this oil in my lawnmower and it works great. I have not had any issues with using this oil in my equipment. I use the same brand but different weight in my vehicle. I like the synthetic oil due to its longer lubricating capabilities.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic Oil is high quality and long lasting. It has the highest protection for my internal engine parts and will be a constant in the my oil changes moving forward. It has made my engine and car run smoothly which is fantastic.

[This review was collected as part of a promotion.] This is a very good oil that produces a very good used oil analysis reports. It appears to do a very good job of keeping the internal clean, And although not designed as a long drain interval oil you can’t push the limit. For instance I’ve went 15,000 miles with a turbo.

[This review was collected as part of a promotion.] I've changed my own oil for many years and switching to a full synthetic makes life a lot easier since it's better for your vehicle and lasts so much longer that conventional oil. Penzoil is a trusted brand that I've used for years so if you want oil the works better and lasts longer than regular oil, it's a no brainer!

[This review was collected as part of a promotion.] I have a late model GMC Yukon XL. Runs great but burns oil more than it used to. I like keeping this around to top off every now and then. Full Synthetic is my choice for extra protection for the high mileage engine.

[This review was collected as part of a promotion.] I started using pennzoils full synthetic oil on both my trucks about a year ago. Long lasting...I typically go about 7,500 miles between oil changes and the oil still looks good when I drain it. Could probably go another 7,500. Not all oils are of the highest quality as pennzoil

[This review was collected as part of a promotion.] Penzoil is a premium brand for your car. It Cleaner pistons , better fuel economy, protects horsepower, unsurpassed wear protection, excellent performance in extreme temperatures Its was very easy to use in my car I did not get the big 5 gallon jug but six regular sized bottles. This is great for my car that does not have high mileage.
