I have an older car with high mileage, this oil seems to last and help my car maintain quality performance

[This review was collected as part of a promotion.] I use it change every 5,000 miles!No noise coming from the motor!

I currently use your awesome products in both my vehicles. Both are pushing 200k miles. And they both run like there's no tomorrow. Go team Penske

[This review was collected as part of a promotion.] I USE THIS FROM MY OLD TRUCK TO MY MUSTANG.CANT BEAT IT BEST OIL I EVER BOUGHT

High motor oil for longer miles and no over heated motor can't stop from a blow down engine at all. That's why I highly recommend this motor oil.

We use this oil and other Pennzoil products on our 1979 Ford and it's never ran better! Always recommend Pennzoil!

[This review was collected as part of a promotion.] My old car is still running great, so that's a pretty good testament to the products I use in it.

[This review was collected as part of a promotion.] i have a high mileage engine(200,000) i trust that shell protects it

[This review was collected as part of a promotion.] I've used this years, on multiple high-mileage vehicles, and it works great!

Love the way my truck runs with this! Making 6 hour drives often takes a toll. Wouldn't use anything else but this gold liquid!
