I have been using this oil on an old rebuilt motor with approximately 140k miles. Ever since I blew my old one due to negligence, so I decided to start fresh with the type of oils I decide to put in my car. Pennzoil High Mileage for vehicles over 75k is just what I needed to maintain protection my "new" old engine. Even after 4-5k miles, I have yet to even burn 1 quart of oil due to its additives and seal conditioners.

[This review was collected as part of a promotion.] Been using Pennzoil since 1978 product keeps improving I'm old school so is Pennzoil the high milage 10w30 is the best for cold starts less engine wear on my older motors thanks Pennzoil for keeping my motors running

I have a 93 land cruiser with 400k on it with worn rings. I had tried every high mileage oil and was still having to add a quart every 100 miles. I finally went for the penzoil and know I make it till the next oil change with no topping off. Couldn't be happier.

[This review was collected as part of a promotion.] This oil saved me from having to buy a car before I'm ready. I have a 2002 Toyota Camry that has 304,000 miles on it I drive 90 miles a day. I have used your oil for high mileage vehicles since the car hit 100,000 miles and I have never had problems. Thanks for helping save me money.

[This review was collected as part of a promotion.] I have used Pennzoil products in my cars for the past 20 years and now that I have a lot of miles on my Malibu I have switched to High Mileage Pennzoil.. can't say enough about your products love, love, love them! I never have problems with sludge in my engines as I had prior to using Pennzoil!!

[This review was collected as part of a promotion.] I bought this for my 2006 Pontiac with 150,000 miles. I noticed that over other brands this one actually worked. I only had to add about 1/2 of a quart over 5000 miles instead of the usual full quart!

I have used the Pennzoil high mileage for a few years now and don't want to try another. I have gone over my limit in oil changes a few times and still looks great when I drain it. My truck runs smooth and doesn't miss a beat. And for 237000 miles it's saying a lot! Would absolutely reccomend high mileage for any vehicle. I wouldn't use any other.

I bought this for my old high school ride a ponitac firebird witch I had kept in good condition, witch had 15000 miles on it and a oil changed it to this runs like brand new best oil for any car I have changed to and I plan to change my other cars to penzoil when the time comes
