it's what i use for the last twenty years for my 95 truck

I used this on my high mileage car and it worked great!

My suv has 143,000 miles on it an this oil keeps it running smooth

Never had an issue with Pennzoil High Mileage motor oil, overall very good oil.

Used this product on my old cars when I change my own oil

I have used many brands of oils for my cars this is superior to any other

Used this all the time when i had my grand prix with over 200k miles.

Reduce sludge in my engine by 70% better then any other oil.

I always rely on high mileage because its dependable and reliable.

I put this in my old bronco and now I get better gas mileage.
