[This review was collected as part of a promotion.] This is the only oil I use in my old 98 dodge it's got 170000 miles now and is still a powerhouse now that Iv got my new truck (2004 f150) well new to me nothing's changed still use it every oil change

I started using this product on my 99 olds cutlas. It had 145k miles. Not only did my oil come.out cleaner and thicker than other brands but i noticed a huge power gain. I know use it in my 2005 silverado 2500 HD and it performs great. Ive convinced my whole family to buy this oil and they also love it. Thanks for the great product

I use Pennzoil High Mileage Oil in my Ford Expedition! I use this vehicle to pull a car trailer and haul merchandise all the time. With Pennzoil High Mileage Oil, I know I don't have to worry about oil breakdown on hot summer days and also have protection on the Frigid Cold days!

I've been using this in my truck ever since it hit 75,000 miles. Now, I'm pushing past 200,000 and it's still running like the day I bought it. I expect to get at least another 100,000 out of it, and I'm confident that Pennzoil High Mileage will get me there.

[This review was collected as part of a promotion.] Been using this on my old truck for a long time, it still comes out cleaner than any other oil I've used after running through the motor for 3k miles. take my advice, you won't go wrong with this oil!

[This review was collected as part of a promotion.] My car has over 170k miles and I'm cheap so I refuse to buy a new one until it kicks the old rust bucket. I've been using this oil for the past few years and will continue to use it until I have a car with low mileage. Vehicle has no noticeable engine/oil related problems so if it ain't broke, don't fix it.

[This review was collected as part of a promotion.] I change my own oil on my vehicle which has over 100K miles on it and use this Penzoil high mileage motor oil on every oil change. My vehicle runs like new and I attribute that engine performance to the performance of Penzoil high mileage motor oil.

[This review was collected as part of a promotion.] i have a 2002 Hyundai Accent with the 1.6 with 190,000 miles and ive tried a couple different oil brands. all the ones i tried still left the engine with a little tap. i tried this brand, the high mile one and boom, no tap and that engine ran alot smoother. i love this stuff!!

[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!

[This review was collected as part of a promotion.] I bought pennzoil high mileage oil a few weeks ago for the first time and I was so glad I did.With my car having high mileage,this pennzoil has worked great in it and have had no problems.I recommend this oil to anyone who has a high mileage car and is looking for a good,dependable oil!
