Classic! like my car...

[This review was collected as part of a promotion.] I have always used Pennzoil in my Ford Mavericks, and still do! I trust Pennzoil to give my engine the protection it needs, I drive my Maverick hard, I need an oil that works hard to protect my engine.

It's AWESOME!!

[This review was collected as part of a promotion.] My boyfriend is a mechanic for Trans Edge, a division of Mack Trucks. He actually does my oil changes and will only use Pennzoil! I highly trust his judgment and after an oil change my van runs GREAT!!

My Father Swaers By It!

[This review was collected as part of a promotion.] Every month or sooner my father gets a bottle of Pennzoil from Family Dollar for his truck, even uses it as wax for his trunk to wipe it off after he washes his truck and shines the tires with it too!

Excellent oil for a conventional base.

[This review was collected as part of a promotion.] I have a vehicle that went over 300,000 miles on conventional 10W40 Pennzoil before needing internal repair (not lubrication related). The crankshaft measured out at near perfect factory dimensions, and there was virtually no internal dirtiness. Saw similar results to this in several other engines at tear down after anywhere from 100,000 to over 400,000. No other oil has proven as reliable.

Works as hard as i do

[This review was collected as part of a promotion.] Ever since I started using it in my truck, the truck has performed better and it seems to last longer than other oils I've run in it. Used to just run around the Air Force Base, and now living in Florida, it still seems to out last others.

one of the all time classics

I have been using this oil since 1984, I blew up my engine on my 1983 monte carlo when i removed the block there was a thick layer of goo all inside, At the time I was using quaker state I switched oils and have never had a issue with my engines I have owned 5 cars since then all with well over 150000 miles put on them by me not one issue. I used it in 4, 6, and 8 cylinder engines I dont believe i will ever use another type of oil. tried and tested by me!

This oil....is down right number #1.

[This review was collected as part of a promotion.] I've been using Pennzoil for quite a few years. I'm very impressed how it stays clean for many miles. But at the end of the chance period it cleans all the impurities out. I use this in my 06 Dodge Ram, 74 Plymouth Duster, 92 Z34 Lumina, 98 Durango mud toy, my fiance's uses platinum synthetic in her 08 Hemi Charger. Like I said. This is the best oil around. Weather it's for a classic, a play toy, daily driver, or high HP applications.

My motor still runs strong

[This review was collected as part of a promotion.] I've always used this motor in all my vehicles. Even though I've sold most iv kept on, that is my 1989 for f150 with the in line 6 cylinder engine. 340,000 miles later still runs perfect with no smoke. Nor any motor rebuild or swapping. Original piston, rings, block etc!
