[This review was collected as part of a promotion.] From the 1st time I changed the oil in my 62 Chevy C10 in 1975 I have used Pennzoil SAE30. It has never let me down. That truck is in my driveway today 40 years later with SAE30 !

been using this oil since ibought my truck new 143.000 miles ago change it faithfully every 5.000 miles and have never had a problem oil is still clear when i change it,

I got an old 65 Chevy c10 with a 396 stuffed in there and I only trust the best.!! That pennzoil motoroil is what works flows in my Frankenstein.!!!! " it's alive."""!!!!!

My 1988 Mercury Grand Marquis GS is extremely picky when it comes to oil. If I get anything other than Pennzoil, it runs rough and fuel economy goes down. Pennzoil is cheap but extremely great, especially for older engines.

[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.] Growing up I was raised with Pennzoil being the only thing my Dad would use on all his cars and truck. I use it still today because like my Dad I can always depend on Pennzoil.

[This review was collected as part of a promotion.] I use Pennzoil in my 360 Sprint Car and it never lets me down. After switching to SAE 25W-50 GT Performance Racing Motor Oil my engine always looks new when apart for freshening. Thanks Pennzoil !

I use Pennzol motor oil and have been very pleased. There are other oils I've used and liked but I'm a J.Logano fan so I sipport the sponsors that support my drivers - thank you
