My father always had a case of this stuff on hand- it's the only oil he'd ever use. All of his vehicles, from 1970 Dodge Challengers to Ford Aerostars and everything in between, have ran smooth as butter.

[This review was collected as part of a promotion.] I live in ND, it gets very cold up here in the winter. All I use is Penzoil, Truck, car, snowblower all drink Penzoil because it's like a steroid to them. Easy starting at -20!

[This review was collected as part of a promotion.] I like the oil. It does keep the engine running well and creates very consistency in my cars performance.

I had a lifter noise at start up. I changed brands of oil to Pennzoil and my lifter noise disappeared! Nobody will EVER tell me oil doesn't make a difference! A great product and will NEVER use another oil! Thank you Pennzoil.

Everywhere you look and all you see is snake oil, well the guys at pennzoil made the good stuff easy to find its bright yellow and still looks the same as when dad was changing the oil and mom was changing my diapers.

I have Always used Pennzoil 10w40 in my Cars Trucks Motorcycles Tractors Mowers & Off Road Toys ! Three cars over 2oo,k mi. Two Gold Wing Motorcycles over 250,k mi. No Major Engine Repairs on any of then.

Just had my oil changed before I made a 1500+ mile journey and of course we used Pennzoil!! The mechanic gave me a really cool Pennzoil sticker too! Everyone in my fb Joey Logano group wants the sticker now!

[This review was collected as part of a promotion.] I dont have the newest or best car, but my son only lets me put Penzoil oil in it. Thats what he has used for ever along with his brother and daddy.

[This review was collected as part of a promotion.] I have used this oil in my truck for quite some time now and it is great.I have never had a problem with pennzoil and will continue to use it.
