Have been using for 22 years and have 1010000 miles on my wife's 2000 RAV 4 change every 5000 miles and does not burn any oil, don't have to all oil at any time

I have been using Mobil 1 for more than 3 years now for my 2 old cars, 2001 Ford Explorer and 2001 Saan 9-3. They have been running smoothly. I have been doing DIY so I can choose only Mobil 1 to put in my car.

I use this oil in my 2006 Jeep Liberty been using Mobil 1 since 200 miles now has 119,000 on it. I usually change 2 times a year which is about 7,500 miles but I drive in town and more than average idling. Will use in next vehicle I buy in 6 months.

I use this to keep my cars protected. My drag car and my track car are changed at normal intervals but the added protection keeps the engines in great shape and is worth the little extra cost on high performance cars.

I use Mobile 1 Extended performance on all my vehicles diesel and gas. I personally have never had an issue with any engine while using Mobil 1. It keeps my vehicles running smooth and like new.

I drive over 120,000 miles per year and one of my cars,a 1992 civic has 738,000 miles on it.I use only mobil 1 5-30 ep in it and the engine runs like new.

I have been using Mobil 1 for years. This is the only synthetic oil I have ever used. Engine runs so smooth, awesome fuel economy, awesome performance. I will not use anything but Mobil 1 oil or differential oil.

I have been using this oil for over 100,000 miles at speeds up to 130 mph, and on the freeways of SoCal. Best oil I have ever used. When changing oil it still has good color not even close to being black.

My Dad delivered Mobil products for 40 years. I use Mobil 1 EP in my 5 cars and 3 mowers and never had a failure or engine that burned oil with once a year changes. You can't ask for more than that!

I tried all other synthetics I prefer Mobile 1 over all brands I use nothing other than Mobile 1 on my Escalade.
