I use this every time In my car and it has 230000 miles. Still going strong!

It's the only brand I buy very satisfied with its durability

I use this oil in all my cars and it's done a great job wouldn't change my oil with nothing else.

Been using this in my girlfriends car that has 276k on it only brand I trust

Have and old Ford f150 this oil keeps it running like a champ.

Used in my 1999 Subaru haven't had a problem since

I have been using this product for years in both my vehicles.

When I need oil I will go shopping straight for my number one oil which is Pennzoil.

Works great in my 94 Toyota Camry with 314,649 miles on it.

I have used pennzoil since my cR was new and as the mileage grew I switched to the high mileage
