[This review was collected as part of a promotion.] I switched over to this Pennzoil Full Synthetic oil for my older riding lawn mower. It's better for the engine and I love the fact I have to change it less frequently. My mower seems to run smoother since the switch. Pennzoil is a brand I trust and will continue using. Highly recommended!

[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.] This came at a perfect time as my car needed an oil change. I usually go for Pennzoil brand oil because I’ve never had any issues and it is a trustworthy brand. The price is right and is good quality oil.

[This review was collected as part of a promotion.] Pennzoil is the best oil out there. It has yet to let me down and everytime I've tried a different oil, whatever machine I'm using the other oil on doesn't seem to last as long. Pennzoil guy for life!
