[This review was collected as part of a promotion.] i have a high mileage Citroen dispatch 2.0 hdi that is 12 years old now & currently do 1000 miles per week, and since using this oil knocking noises on start up have stopped and fuel economy has increased, so I'll be using it again in the new year, when I'm due my next oil change

I used this on my girlfriend's 02 Jeep Liberty on an oil change, and when I went to change the oil again (est. 4000 mi). Oil still looked good for another 750 mi. That made me switch from Quaker State to Pennzoil. And not to mention we are Penske fans! GO JOEY!

I purchased Pennzoil Platinum for a old honda odyssey that had about 130k miles on it. Due to less than stellar maintenance there was some deposit build up and when I switched to platinum it cleaned out all the junk quickly but left the old seals now exposed and likely more brittle than they should have benn. Anyway after the cleaning the seals started leaking to the tune of about 5 or 6 nice drops each night. I replaced the v tech seal and it stopped that leak but the oil pump leak continued. I switched to pennzoil high mileage and after only a few weeks it has slowed to only 1 drop every 5 days or so and I suspect it will stop all together. Please understand platinum simply cleaned out the junk leaving the old seals that had been hidden dry behind junk to leak but thats not platinums fault its the fault of the lesser oil and longer change interval that was used previously. long story shorter pennzoil high mileage slowed and will likely stopped a leak for me.

[This review was collected as part of a promotion.] I have been using this oil for the past 3 years in my 2007 Toyota Camry. Not only has it helped my fuel mileage, it runs so much smoother. I would refer this oil to anyone with a older car with high miles

[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 decided to try this on a car I used traveling for work. I started using this at 100k miles and the car kept going without any issues or smoke... So I decided to keep driving it. Eventually I sold it with 300K miles and you couldn't hear the car running, nor did it smoke.. Good stuff!

[This review was collected as part of a promotion.] I have a 1995 Toyota Corolla and Pennzoil High Mileage is the only oil I will use! I have tried other oil but once I tried this oil I refuse to use any other oil. It keeps my engine running smoothly, my last oil change the mechanic told me I will be on the road for 300,000 plus miles.. Great news for me!!

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 grew up with my Father using the Pennzoil brand oil as my Grandfather did for as far back as I can recall . I my self have been using Pennzoil High Mileage oil in my 2006 Town & Country since I got it back in 2012 and in other cars before . I have never had a complaint and the oil in my humble opinion in simply the best and ONLY brand I will ever use . My son is getting ready for his first car and will be following the family brand loyalty and using the same oil .
