[This review was collected as part of a promotion.] This oil is the best you can get, at least one that is affordable. It cleans, protects, and lubricates very well. Shake the oil before adding to get all the detergent out, because it may have settled. Pennzoil offsets 100% of the carbon emissions from creating the oil.

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. It is the only oil that goes into them. The full synthetic is absolutely the best, I will continue to use this going forward. If you're looking for a full synthetic oil, this is it.

[This review was collected as part of a promotion.] I got this Pennzoil full synthetic to use in my f150. I usually take it to the dealer and they use a synthetic blend. Well my warranty is up so I figured I'll start changing my own oil and at the same time this will give me a chance to keep an eye on what's going on under the truck. (leaks and such) I've used pennzoil in the past on other vehicles with good results so this was pretty much a no brainer. Time will tell but with a company that's been around this long they must be doing something right!

[This review was collected as part of a promotion.] Used Pennzoil full synthetic 5w-20 at my last change, replacing another brand. I run synthetic in my 2007 Chrysler Pacifica and this Pennzoil is doing just fine after nearly a thousand miles run on it. Seems to do better on it than the previous brand, which was already a huge improvement over conventional oil.

[This review was collected as part of a promotion.] I desperately needed oil for my truck and I only use synthetic so this couldn’t have come at a better time. And I Already tell a difference in performance. Pen soil is awesome!! My truck purrs like a kitten

[This review was collected as part of a promotion.] I got 6 quarts of Pennzoil Full Synthetic. I changed the oil in my car and used this for the replacement. I don't know if this is possible but after about 10days of use I truly think I am getting better gas milage. The car runs quieter than before. This is a good product and everyone should be using a synthetic in their car.

[This review was collected as part of a promotion.] Engine oils Came in 1 qt 6 packs, took it to my mechanic, they changed it into my 100k Toyota Camry, and got it inspected. I’ve been driving it 80 miles a day, from Long Island to nyc, back and forth, no problem , running smoothly.

[This review was collected as part of a promotion.] Penzoil is a premium brand for your car. It Cleaner pistons , better fuel economy, protects horsepower, unsurpassed wear protection, excellent performance in extreme temperatures Its was very easy to use in my car I did not get the big 5 gallon jug but six regular sized bottles. This is great for my car that does not have high mileage.

[This review was collected as part of a promotion.] I have never tried the synthetic oil previous to this. I heard rumors to stay away from synthetics in the past. My son in law is a farmer,( they use a lot ) and he is the one that convinced me to try it. I have it in my riding mower and truck. I guess I had some bad information.

[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.
