[This review was collected as part of a promotion.] This is the best oil that I have used. It is long lasting and my vehicles run great with it. I will not use anything else in my vehicles and I think that their life is extended from using this. I wish I would have switched earlier... Well worth the money.

[This review was collected as part of a promotion.] I am a huge supporter of the fully synthetic oil. Runs great in my jeep and I have never had an issue with it. I do all my oil changes myself and have been a pennzoil man through and through. Superior product at a superior price!!

[This review was collected as part of a promotion.] Since 1913 Pennzoil has been a true and trusted product for autos. And they've continued caring for our cars and trucks by coming up with a full synthetic oil that not only better protects our engines, it also outlasts regular oil allowing more miles between oil changes. It's a great product for my car which has over 200,000 miles, and is still going strong.

[This review was collected as part of a promotion.] I use this oil in my lawnmower and it works great. I have not had any issues with using this oil in my equipment. I use the same brand but different weight in my vehicle. I like the synthetic oil due to its longer lubricating capabilities.

[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 changed my oil with this Pennzoil Full Synthetic oil and will update this review in two and a half months after I complete another oil change. I put my old oil in an airtight container and will compare the Pennzoil to that once I do my next oil change. I have no other way of knowing how well the Pennzoil works other than to compare it to the brand I regularly use. I’ll be back! My wife says I can’t update reviews, so I will complete another review after my next oil change.

[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 prefer using a full synthetic oil in my cars. This Pennzoil 5W-30 has worked well and I have had no issues with it. The bigger jugs make it easy to pour in and cuts down on plastic with the smaller bottles. I recommend this full synthetic oil.

[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.] I got the Pennzoil Full Synthetic 5w-20. If you change your own oil this is the oil for you. Pennzoil Full Synthetic motor oil is made from natural gas which makes it much more pure than oil made from crude. It is proven to provide better protection and lasts longer than oil made from crude. Compared to other oil Pennzoil works great on my 2008 Dodge Ram pickup with high mileage .I would definitely recommend.
