[This review was collected as part of a promotion.] Pennzoil helps to keep my Buick on the road. While I'm not that great of a driver to notice every little difference an oil makes, Pennzoil has always been a quality brand. I use the 5W-30 to top off my car if I notice the oil goes below the fill line before I get to my mechanic. It's a Mom N Pop place and you can bring your own oil along for the oil change. I like that this Pennzoil gives me more miles between changes and keeps my engine running smoothly. 

[This review was collected as part of a promotion.] I love this brand of oil, especially the full synthetic type. Use this in my 14 Edge and go for 10,000 miles. I've used many different brands over the years, but always go back to Penzoil for it's quality and availability.

[This review was collected as part of a promotion.] I have used only Pennzoil products in my vehicles for years, it’s a trusted brand that always delivers. I’ve never had any issues with Pennzoil, and would highly recommend their products to everyone that would listen

[This review was collected as part of a promotion.] This motor oil works great for my car. I used it for an oil change and had no problems. I also love the handles which makes it easy to carry. The scent is overpowering but its to be expected with motor oil

[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 Pennzoil Full Synthetic Oil is high quality, affordable, and made by the best in the business; Pennzoil! I love the design of the bottle as well for a nice even and smooth pour. The additional handle comes in handy when putting it into the funnel.

[This review was collected as part of a promotion.] You pay so much for your car, so you definitely want to use the best products for it and this oil is definitely something your engine will thank you for. I've never had any engine issues when using this type of oil and it runs smooth.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is entry level synthetic oil for people changing from regular oil or blend to full synthetic oil. Pennzoil is great and I always depend on it to keep my vehicle running smoothly

[This review was collected as part of a promotion.] This full synthetic oil is just like the Review Title says, "Super slick!" My engine runs really smooth with this oil. Obvious benefits of friction reduction of engine components have resulted in a boost in fuel economy. Granted, I don't have a physical/measurement comparison, since I have not taken my engine apart to do so, I'm confident it's doing what it's supposed to do.

[This review was collected as part of a promotion.] This oil works great! Car runs well. Pennzoil has always been a good quality company and one I can count on for knowing I’ll have a good quality oil in my car. It works great and car runs well. Easy to change.
