I used this Pennzoil 5w-20 (synthetic Blend) on my 2004 Lincoln Navigator 5.4 engine with 250k miles and it has helped to stop small leak around the seal on the bottom of the engine. I have been using this High mileage on the last 50k miles and I have no complaints. I change my oil every 3k-4k miles or twice a year due to the high mileage on the vehicle.

[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 use the high mileage in my 72' pick-up.Could not tell you how many miles are on the truck but it runs like a new one with the high mileage PENNZOIL it does not rattle or squeak like it did before the PENNZOIL

[This review was collected as part of a promotion.] I have been using the high mileage in my tahoe for about 5 years now. After the first oil change I noticed the oil was not as dirty as before, so that means it is doing a better job than the Castrol that I used to put in. I am penny oil for life

[This review was collected as part of a promotion.] Over the years, my husband and I have had a multitude of older used vehicles, and we have found that Pennzoil for High mileage vehicles not only runs cleaner, but has added to the life of our vehicles. And because we have had such wonderful experience with the Pennzoil for High mileage vehicle , my parents that have a delivery company also use it in their delivery trucks. We are, and always will be a Pennzoil family.

[This review was collected as part of a promotion.] I've used many different brands of High Mileage Oil. I'm old school I change my oil myself. At oil changes I noticed that other brands of oil felt like canned lubricant oil. Towards the end of the oil change cycle my oil pressure would not be slightly lower than usual. When I used Pennzoil High Mileage Oil it felt the same coming out of the oil drain plug as it did when I poured it into the crank case. The oil pressure was never affected with Pennzoil. My brand of oil is Pennzoil simple as that. Always has been, always will be.

[This review was collected as part of a promotion.] I've always been told to get Pennzoil for all my cars. High mileage works the best for me considering I drive 44 miles one way and have for over 20 yrs. Never a problem... you just stay loyal to some thing that's works.

It arrived with the oil leak from two bottles and the whole box was oily. Leaked about 80 mg. Other than that, this was a good item for a good price.

2 years ago I switched motor oils to Pennzoil high mileage. The other high mileage oil I was using left a lot of sludge throughout my engine. Also seemed like it burnt quicker between oil changes. But after switching I no longer have sludge and my oil looks like it should at 3000 miles. Thank you for a great product!!!

[This review was collected as part of a promotion.] I have 4 cars, and the newest one has 122,000 miles. Synthetic blends like this take some of the worry out of the longevity of my engines, and saves me the cost of more expensive full synthetic oils.
