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.

I have been using pennzoil in my 95 ford f150 302 v8 the past 2 yrs i have owned it. I have had no engine issues and the engine burns no oil. Before that i used it in a 93 ford ranger 4.0 v6 with 287,000 miles and never had no oil related issues. I am a firm believer in pennzoil products!

[This review was collected as part of a promotion.] I drove a 2002 VW Beetle until 2012... it's had over 200k miles on it, I barely took care of it but I put high mileage oil in it from Pennzoil. I truly believe without this oil, my car would have never made it that far! Extrodinary!

[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.

Pennzoil High Mileage is what I use in my '84 Blazer and it has been doing a really great job, no knocks, pings or other noises, no sludge with oil changes and the engine runs like a top. If anyone were to ask me what I use, Pennzoil High Mileage would be my answer. To my knowledge(what we were told when we were given the Blazer) it still has the original engine, so with it being a possible 30 year old engine I know to use a high mileage oil and your oil is what I always use and I am really glad that you produce a High Mileage oil because I really would not like to switch to another brand. As far as I am concerned you have the best oil products on the market and always will have.

[This review was collected as part of a promotion.] I have used this oil when I rebuild engines and the engines just keep on going. I have a few that are over 250k miles on them and they are still reliable and not burning any engine oil at all. I will continue to use 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.] 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

my car is approaching the 20 year mark so a few years ago i started to switch to the pennzoil high mileage oil in order to save my engine a little bit from the wear and tear from me driving. before I made the switch my car would make a griding noise at points coming from somewhere in the engine. nothing too serious sounding, but since i made the switch it has been nothing but smooth rides for me and my Pontiac

I have been using Penzoil High Milage in my 2004 Ford F-150 ever since I bought it used with 198,000 miles. I am up to 229,000 miles now. I have not experienced any lubrication issues and will continue to use this product until she gives up the ghost.
