[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.] I recently tried Pennzoil full synthetic 5w20. After I changed my oil and filter I noticed more power during acceleration and less delay in my engine. I highly recommend Pennzoil products to bring your vehicle to life.

[This review was collected as part of a promotion.] I decided to try Pennzoil's Full Synthetic motor iol. Pennzoil is a long-standing brand known forever for quality. I llike that this oil is designed from natural gas instead of from crude oil like other synthetics meaning less impurities right off the bat. That means better performance and longer lasting at a higher level. I need that because I put a whole lot of miles on my vehicle and besides the fuel, your oil is the 2nd most important fluid your engines uses. I'm seriously thinking of trying their Platinum Plus oil next. With Pennzoil you know that you're always getting the best there is.

[This review was collected as part of a promotion.] I use this for a multitude of things that uses this oil. It works perfectly in my car. I don't think I have ever had my car run so well before. It seems like it runs smoothly as well. I went on a few trips already out of state and there hasn't been an issue.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic is their top of the line oil. I have used it for years and it keeps the engine clean and running great. Meets Chrysler and Ford specs along with many others. 5000 miles between oil changes is no issue!

[This review was collected as part of a promotion.] Great motor oil! I switched to synthetic on a few of my high mileage vehicles and I’m convinced that Pennzoil has increased the life of them! I know they say you can run longer between oil changes with synthetic but I still change it at 3k. 180k on one of my trucks and still runs like new!!

[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.
