[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 use this for a multitude of things that uses this oil. It works perfectly in my car. I don't think I have ever had my car run so well before. It seems like it runs smoothly as well. I went on a few trips already out of state and there hasn't been an issue.

[This review was collected as part of a promotion.] I recently received the Pennzoil Full Synthetic motor oil and immediately noticed a difference in the way my vehicle ran after use. The oil, which is certified by the American Petroleum Institute, allows my car to run longer between oil changes and increased the fuel efficiency. Over time, choosing full synthetic compared to regular motor oil will save you plenty of money. I have even noticed a difference in the way my car drives, most likely based on the advantages this oil provides to my engine. I would highly recommend this motor oil, especially to anyone looking to protect their vehicle while also saving money in the long run.

[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.] 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.

[This review was collected as part of a promotion.] This is a great quality and amazing oil for your car. I suggest you shake this bottle very well as the additive falls to the bottom of the container and you want this to go in your car correctly the additive looks like a sandy type material on the bottom of the container. The oil is just right to get the engine running well. This truly works wonders for my car.

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic motor oil really is a terrific product this motor oil really helps keep your car running in tip top shape if you haven't already you really need to give Pennzoil a try you will not be disappointed.

[This review was collected as part of a promotion.] Ok, maybe 'life-blood' is a little bit of an exaggeration. It is true, however, that your engine relies on lubrication so all those metal parts move freely and your investment(vehicle) gets you from A to B. I've been using exclusively Penzoil Platinum 5W-30 on my vehicles for almost.

[This review was collected as part of a promotion.] I have always used Pennzoil products in all of my engines. When I recently purchased a newer car, I had the chance to run the full synthetic. Now I have changed over to the full synthetic in every application possible. This stuff is the good stuff! Great bottles with easy to open/pour packaging.

[This review was collected as part of a promotion.] I have used many oils on my 2014 Acura and have always consistently found the oil to be dirty during every oil change. But after trying out the Pennzoil synthetic for the car, I can totally see the difference. This is a very good oil and does a great job in keeping all machinery clean. It's definitely a high quality oil that dealers would use. Eventhough I don't need to change oil for a while, I'd love to keep changing every 4-5K miles, to keep the inside machinery clean and running smooth. I'd say this is the best oil you can find for your vehicles that you want to keep running longer, and ones that you drive daily. I'd definitely recommend.
