[This review was collected as part of a promotion.] It was service time for my Lexus and it requires 5W20. Previously, it would get maybe 16mpg in town and 22 on the road. Average at best. After the change to this synthetic oil, my mileage improved a solid 1 mpg both in town and on the road. Impressive for something so simple.

[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.
