My truck is 16 yrs old with 158,000 miles. I have been using Pennzoil since my first oil change. The oil still looks clean in the engine today. The Mechanic who did my alignment said he wa impressed with the engine performance. Asked if I wanted to sell my truck to ask him first.

I've used Pennzoil conventional in just about every mopar I've ever owned including my current cars, '08 Durango (86k miles) and '05 neon (84k miles). Despite negative hearsay seen on online forums as well as in person I've never had any issues with it. I will continue to use it and would recommend to anyone!

I have been using 5W-20W in my 2013 Chrysler 200 for 6 years changed every 6,000 miles and my car runs very smoothly. High recommend Pennzoil.

Pennzoil has been around my house since i was a little girl. Daddy swore by it.Good quality and fair priced. Daddy always had a quart in his old truck

My wifes car is a 2000 buick lesabre ,bought new sept 1999 .At first oil change Installed PEnz10F30 .t This car now has almost 300k rus like a top uses no oil between changes and has not required any repair

I never have to stew over makiing a decision for which motor oil to purchase. I just look for the Pennzoil. It has never failed me; my cars all like it. So I like it too!

Good Product.

I work at a service shop that supplies Shell and Pennzoil products. I have used Pennzoil in my gas engines, and I have seen oil filters from previous services where Shell and Pennzoil products were used. Shell conventional oil is formulated to -control- and limit the formation of sludge, while Pennzoil conventional oil is formulated to =prevent and remove= sludge from the engine; the difference shows. For better cleanliness and engine performance in a conventional oil product, use Pennzoil.

In 2005 I bought a 2006 dodge ram 1500 hemi the first day I drove it to the shop an change the oil an put in 5w20 gold the reg stuff an here it is 10 + year later every 5000 mile I change the oil same stuff everytime now the truck has around 140 k on her an it run as strong as its every had thanks Pennzoil your tha best
