I have used Mobil 1 High Mileage in two Land Rover Discovery Series II ('99 & "01), with great success. I now have a 2002 Toyota Land Crusier and will be using it as well for the same reasons: viscosity, protection, anti-wear. Unfortunately, other oil companies use creative advertising to try to earn my business. Case in point is Valvoline. Their website states their full synthetic high mileage motor oil is "Formulated with...40% more anti-wear film than Mobil 1*. .... *Based on anti-wear film generated in Cameron Plint Test, Valvoline Full Synthetic with MaxLife Technology™ 5W-30 vs Mobil 1 5W-30". Well, Valvoline is comparing their fully synthetic high mileage motor oil not to Mobil 1 High Mileage, but to standard Mobil 1. Why not compare apples to apples, or mention that the Valvoline oil flows slower in the centistokes test than Mobil 1 High Mileage? When you are the synthetic oil standard, you are a target, but this is just rediculous. Mobil 1 motor oil protected my engines, and Mobil 1 lubricants protected my differentials, transfer cases, all of it, for years. I trust it and it has never failed me. 'Nuff said.

I have had a 2006 Chevy Silverado for almost 15 years. It developed an engine leak 13 years ago . The repair job was expensive and I learned to live with problem. Under warranty the dealer wouldn't fix it. The truck only still has 35000 miles. I've tried other hi mileage oils.Unbelievably, it stopped-completely! I'm elated. Thanks Mobil 1.

[This review was collected as part of a promotion.] My first car was a 2005 legend lime mustang; when I got it it was almost 10 years old, but it was so much fun having a mustang as my first car! I named him Avo, short for avocado, and when I was ready to start a family I passed on Avo to one of my brothers, and when he was ready to join the Air Force he passed it on to our youngest brother who is now a senior in high school. So for the past 6 years Avo has been a really important part of our family, and we have put a lot of miles on him. Avo the legend lime mustang is now 16 years old and has almost 180,000 miles, but we really try to take care of him since we all love him so much. My dad and youngest brother changed Avo’s oil last week and used Mobil 1 High Milage 5W-30, which is a different brand than what they usually use. This is what my brother had to say about this Mobil 1 oil: “Overall, this oil worked fantastic in my car and the improvements it made were noticeable. Normally I use a different as its pretty good but after trying this one I can certainly say Mobil was better. Mobil made my car feel much smoother when driving it and accelerating felt like I was putting less strain on the engine than usual. My car also felt much better at higher revs than it normally does. I also enjoyed this oil due to it lasting 1.5x longer than most and the fact that it was made for cars with higher mileage. This was especially important since taking care of your car at high miles allows it to last longer. I would definitely recommend this oil as the cost is worth the improvement to driving and the fact that your car will last longer with better oil.” So yeah, from now on Avo the legend lime Mustang will only be using Mobil 1 High Milage oil, and we will try to keep him for many more years to come.

[This review was collected as part of a promotion.] The mobile 1 high mileage 5w-30 is just what I need for my SUV. My trucks been around awhile and it needs the good stuff and this here is the good stuff. The bottle design makes it easy to pour in and see how much is in the bottle. Mobile 1 is one of the best brands.

Bought my 2011 Nissan Frontier in 2014 with 48,000 miles. Used Ester oil until it became 15.00 qt. Savey mechanic said use Mobil 1 full synthetic high mileage up to 20,000 miles. Glad I did, my truck now has 202,700 miles on it and actually runs better then the ester oil did. When I took it in this last time the mechanic said he could not believe how clean my engine was for the amount of miles it had!!! Let me know my engine is still strong. Of course the dealership tried to get me to trade it in....hahahaha NOPE

I have a 09' Altima with 110K miles on it. I drive and sit in Boston traffic every single day of my life and Mobil 1 High Mileage is all I have used since my car turning 75K miles. Prior to the High Mileage, I used regular full synthetic Mobil 1 5w-30. In all honesty, my car sounds great. Very quiet, smooth, people often comment on it, especially being a 4 cylinder that takes a beating with Boston traffic. I change my oil myself every 5,000 miles and it still looks good. It is impossible to go wrong. Sick with Mobile 1 High Mileage with a Mobil 1 Extended Performance filter and you'll be more than fine. Be good to your car and your car will be good to you for a long time. After all, who likes a car payment?

2012 Jeep Liberty with 248,000 Miles. Have been using Mobil 1 synthetic oil since day one. Mobile one high mileage full synthetic since 100,000 Miles. I changed the oil every 6,000 miles and use a K&N or Mobil 1 synthetic oil filter. I do add one quart of Lucas full synthetic oil stabilizer on every oil change. Combination of full synthetic Mobil 1 and Lucas I feel like I can get 500,000 miles on my vehicle. I would recommend this oil to anyone who has a high mileage vehicle.

Began using Mobil5W30 synthetic oil in my 89 Plymouth Voyager and the engine lasted 24 years without any problems whatsoever...sold it to purchase an 05 Chevy Equinox and have used Mobil1 5W30 from 2005 to this day witj no engine hiccups or problems. I am a firm believer in Mobil1 synthetic oil and will never use any other type in my automobile engines. Great great product.

I am of the belief that changing the oil every 3000 miles is a waste of money considering most manufacturers recommend more than double that value. That said, I tend to change mine every 5000 or so miles and switched to Mobil 1 high mileage when my Saturn Aura hit 180,000 miles. The engine still runs strong and is very quite and I now have close to 260,000 miles and climbing. I was a bit concerned making the change at such a late stage in the engine's life might promote leaks but the engine is still tight a s drum so I'm sold. Highly recommend this product to anyone.

My name is Allen Parfait. We live in Jackson MS. We race a street stock dirt car every weekend. I built our motor three years ago. I decided to freshen up the engine on a 3 week down time between races. I pulled the The rod bearings and mains bearings down . They still had the grey coating on them after 3 years of abuse The crank only had to polished and the cylinder walls still had the X Crossan from when it was honed . Thank y'all for the cost saving and the reliable oil. Mobile one synthetic is all will ever run Allen Parfait
