I used this on my 95 f150 with a million miles on it. She ran like a champ

Penzoil hi mileage is great stuff would definitely recommend.

I drive some good high mileage cars and this stuff is great! Love it!

I have a high mileage car and I use Penzoil high mileage. It helps with the fuel mileage.

Superior protection for high mileage vehicles. See an increase in HP and MPG

Works well for cars with 150,000+ miles. Use it for every oil change

we been using this oil in my sons truck n he gets great mileage

Bought this for my older chevy truck and it's still running like a Swiss watch!

I use this oil in my high mileage car before it ran rough and now it has smoothed out

I always buy THIS and never worry about my oil! Only Pennzoil, from dad to me to kids!
