[This review was collected as part of a promotion.] Full synthetic is great for my wife's car. Got these to keep in her trunk, she gets paranoid when her oil goes below 15 percent so she can keep this for those days. Until I can get around to doing the oil change.

[This review was collected as part of a promotion.] This is my first time using full synthetic oil and I wouldn’t do it with any other company than Pennzoil. My buddy has been trying to get me to do this for several years but I have been stubborn. I finally decided to give it a shot and put the Pennzoil Full Synthetic in my truck. I have seen a difference already in the way my engine runs. I took it on a 4 hour drive and it was smooth as it was the day I bought it. I am looking to get an extended period on the full synthetic. I will continue to monitor this over the mileage. This oil was packaged in nice quart size individual packaging. Easy to pour and easy to grip. I am currently satisfied and would recommend this oil to anyone looking for a full synthetic oil.,

[This review was collected as part of a promotion.] I bought this to try the Pennzoil brand on the full Synthetic oil and seems to be good quality, used it on my 2015 jeep renegade, will see after 1000 miles how is the color and texture, the kit is convenient and had enough oil for the change

[This review was collected as part of a promotion.] Recently did an oil change and my thought always was that all oils are the same. I was wrong. My car was actually quieter and burned less of the Pennzoil than my previous brand. Seems to last longer also as I checked my oil and it was not black or dark as usual. Very pleased and will be using Pennzoil in all my cars for now on

[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 use the pennziol product in every piece of equipment I have. Tractors, trucks, boat, chainsaws. I never have to worry about the product. It has been around for many of years. It has changed with the times. I used this product in my pickup truck. The labeling is great the color of the plastic jar is yellow and has been for years, can’t miss it. Thank you to all of your people for it.

[This review was collected as part of a promotion.] I switched to this after using a competitor's full synthetic, and have noticed a difference in my higher milage car. The idle is significantly smoother, as well as engine noise has been reduced. I'm looking forward to harsher driving conditions this summer due to additional heat to put it to the test, but as of now, I have no worries its up to the challenge!

[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.] I exclusively use Pennzoil for my car, and it hasn't let me down yet. The engine performs the same or better in this than with the oil recommended by the manufacturer; the Pennzoil almost makes the engine "purr" softly when idle. From what I've read in studies of different oil manufacturers by independent third parties, Pennzoil is in the top 3-4 overall oils when it comes to engine wear, how clean it keeps the engine, and resistance to breakdown. In other words, it appears to be exceptional value for the quality of the oil.

[This review was collected as part of a promotion.] I use and will continue to use full synthetic in all of my had run engines. Those are all my small engines and my SUV with the turbo on it. Anything that is labeled eco-boost or has a "t" in the model name has a turbo in it and probably already calls for it. Pennzoil has never let me down and I'll continue to use it.
