[This review was collected as part of a promotion.] I decided to use this in my 95 explorer since it has trouble with dry start and I can say this definitely helped out during the heated days. Oil seems to keep the same protection as 5w20 but flows much easier for that old oil pump. I’d definitely recommend this to anyone having a slight lifter tick.

[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 purchased this pennzoil motor oil due to needing an oil change in my truck. I always use pennzoil full synthetic motor oil. This is great oil and I would definitely recommend this oil for anyone needing oil.

[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 really like Pennzoil Full Synthetic motor oil. Pennzoil has been around for over 100 years so they know what they are doing as far as motor lubrication is concerned. This oil should be great in my lawn equipment and generators.

[This review was collected as part of a promotion.] This is a really good brand of oil. I was honestly surprised how much came in the box. I haven't had to use it just yet but I have bought this kind before and never had an issue. Will definitely get more when the times come and would recommend to anyone.

[This review was collected as part of a promotion.] I have for a very long time wanted to try a full synthetic motor oil in my vehicle, after using this product I will never go back to regular oil again. I notice o get better gas milage and the car runs much smoother.
