I change the oil in my 2005 Tundra every 5000 miles or less and have used Mobil One since I bought the truck in late 2004. It now has 251,000 miles on it and runs great and does not burn any oil between oil changes. I just switched to the high mileage oil and am happy with it too.

I switched to 5W30 Mobil1 for my last oil change at 107240 miles. Being preoccupied in moving to a different state earlier this year I overlooked the scheduled oil change. Today I was shocked to see my 2000 4 Runner LTD has added 9k miles since the oil change! The 9k doesn't say much for this driver but says a lot for Mobil 1. During this period there was no evidence of oil usage and the oil stayed clean.

We have 2 vehicles, a 2003 Ford Explorer Sport trac, and a 1999 VW Jetta. Both have high mileage and I am a sticker for changing the oil and filter every 3,000 miles. This oil has held up to it's reputation but believe that Exxon Mobile could throw a few coupons our way once in a while. I perform most of the work on our vehicles and would like a discount every now and then. If you look on their web site the coupons that they have list all expired in 2014. Come on guys catch up and give us self doers a small break. Love the product but believe that Exxon Mobile could help out the little fella here. Jim Barnes El Paso, Texas

[This review was collected as part of a promotion.] Works well, easy to find in most stores that have an automotive section and my car is running beautifully on it. It doesn't leave a lot of build up in the engine and offers a fair amount of protection for both the hot or cold weather. I do a fair amount of interstate travel and feel this is a great option for those competent enough to change their own oil.

My grandpa bought my Yukon brand new and was very particular about having Mobil1 full synthetic oil in it, to the point that he'd drag a case of oil with him on cross country trips just so a lube shop could use his oil. I bought the truck from my parents after my mom inherited it, but I couldn't afford his taste in oil, so I used generic conventional oil. I got tired of the noisy, rough idle and clattery starts, so switched back to Mobil1, and the difference was night and day. I had a new motor it seemed! Power came back, the idle was silky smooth and silent, and I could go twice as long on a change with no issues. Now Mobil1is the only oil I'll use in my vehicles and I attribute this oil with making the original motor act like new with 250,000 miles on the clock. Great stuff!

I bought a crown victoria with 146,000 miles and few minor oil leaks. I immediately changed the oil to mobile high milage oil and with an additional oil change 6 weeks later all the oil leaks stopped. I put an additional 100,000 miles on the car and sold it as a daily driver. Never lost a drop of oil between 7500 mile oil changes!

I own a 2000 Toyota Tacoma 3.4L V6 4X4 I ordered new and drive 100 miles per day as well as hunting all over the country on the weekends. Not babied, it is in and out of 4 wheel drive about 30 to 40 times thru out the year. I made the switch to synthetic oil at 200,000 miles and made the switch to Mobile 1 shortly after that. I have kept close records and have changed the oil and filter every ten thousand miles where it needed it or not. Starting out with the standard synthetic mobile oil then switched to the extended life mobile one and final settled on the 75,000 mile high milage mobile one when it was introduced. The engine does not use oil between ten thousand mile oil changes but recently has developed a burnt valve and had to be replaced. It was running perfectly to the end but on just five cylinders.The engine had never been worked on other than timing belts and fuel injectors. I attribute this long dependable engine life to the Mobile one product line and wish I contacted you for your inspection of the old engine. I purchased a used 100 thousand mile engine as a replacement and will be using mobile one synthetic oil products to the end of this engines life. Just thought you would be interested and thanks.

[This review was collected as part of a promotion.] My husband is a mechanic so he buys a lot of oil. We are already a fan of Mobill1 products. It's good quality oil at a fair price. It helps maintain your engine for a better, longer life cycle. You can't go wrong with oil. I would definitely recommend it to everyone.

[This review was collected as part of a promotion.] Mobil 1 is a great oil. I use the high milage in my 1998 ford ranger with every oil change. It keeps the engine running smooth. We also use the mobile 1 synthetic in our 2017 Gmc terrain and our 2014 Gmc Denali. I feel that Mobil 1 makes a great product. I personally haven't had any issues what so ever.

I have had my 1999 Lexus GS300 since I drove it off the lot in 1999. I currently have 196,000 miles on my car. I have my fluids changed regularly, but I change my own oil. Since I can remember, I have been using the High Mileage oil and have had ZERO issues along with Mobil 1 brand oil filters. My car is running like new, even when I put the pedal to the floor. I Change my oil and filter every 5,000-7,500 miles, or every year, whichever comes first. Usually, it is the miles, given that I drive about 10,000 miles a year currently. I will stand by this oil until the day I die, or my car does.
