Loved Penzzoil engine full synthetic oil. Have been using it for years and never had a problem with my 2004 ford Lincoln Navigator. My vehicle takes 7 quarts of oil and buying from Sam’s at this price $32.98 per 6 quarts, I couldn’t let this opportunity passed.

[This review was collected as part of a promotion.] This is my favorite oil. It out preforms all the other oil brands in my book. If you don’t get your oil changed every 3,000 miles this oil will help keep your car moving. It’s just the best in my book.

[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.] I received this product for a honest review. This is really good oil. I used it in my car and I noticed how much better it runs for me. I change my oil regularly and will continue to use this oil. Easy to use and pour. Works great!

[This review was collected as part of a promotion.] Pennzoil is a brand that I have always admired. I use it with the confidence because quality is in it's name. There are many brands to chose from but you will never go wrong using Pennzoil Synthetic. It's a name that's been around a long time and you can trust that.

[This review was collected as part of a promotion.] Used this for oil changes in all my equipment, feel totally confident in the Pennzoil brand, and I prefer Synthetic over traditional oil. The case was just the right amount for all my machines with a spare bottle left over.

[This review was collected as part of a promotion.] I've only recently made the switch to using Full Synthetic oil on my SUV and chose Pennzoil. I change my engine oil every 5,000 miles and extremely happy with the performance of my engine after the first oil change to Pennzoil synthetic. The SUV runs smoother and quieter than before. Engine runs smoothly after

[This review was collected as part of a promotion.] I like the fact that it is better for the performance of my car.I also like that is made from synthetic base oils and in its manufacturing converts natural gas into a high quality synthetic base rather than crude. Better fuel economy

[This review was collected as part of a promotion.] Just did my first oil change with the Pennzoil full synthetic. It was straight forward and easy to use. Excited to see how it performs down the road but it’s working as expected so far! No issues with over heating or oil pressure.

[This review was collected as part of a promotion.] Pennzoil is a fantastic product, very high quality oil that you can put into your car and then have a lot of confidence it will do its job. Love the full synthetic as well as it allows for longer times between changes saving precious time. Solid oil and company.
