This oil does not burn until almost 450 degrees F. Still lubricating when others burn. My Honda 750F with Mobil1 was several bike lengths ahead of friends Honda 750 after changing to Mobil 1. Before they were pretty even. When I sold the bike 21 years later valves still did NOT need adjusting. Looked like new inside cylinder head. Smokey Unick dyno'd Nascar 355 Chevy, went from 303 to 333 hp on the dyno! Just by changing the oil! My Cadillac Northstar 300 hp still is clean inside, gets 30 mpg highway, has 80,000 miles using Mobil1 exclusively. 1978 VW Scirocco engine looked like new inside at 180,000 miles, good compression, was using one quart of oil every 1,500 miles.

I came from a large surface coal mining company and we were owned by a major oil company. We were bound to use their motor oils in our equipment. In thirty years of managing the maintenance department and overhauling and repairing all types of engines I can say that while the major oil companies oils were fine, but there is no comparison in the appearance of the inside of the engines with one that has ran Mobile 1. I recently rebuilt the engine in one of my Corvettes that had 150,000 miles on it. The motor had not failed and was torn down to repair oil leaking from both rear corners of the oil pan. The oil pan itself was at fault and no seal had failed. The engine was clean inside and all bearings looked as good as new. It was in remarkable shape and had used Mobile 1 from the factory till its repair. I would never consider any other motor oil in my Corvettes as long as Mobile 1 is available.

Ever since a friend introduced me to extended wear oil products from Mobil 1 I've been loving only having to change my oil once per year. Be sure to check it once a month in case you have to top off if your engine burns a bit of the oil, but otherwise if you're under 15k miles per year on your car like I am, no need to change it 2-3 times a year, once will do. I've been using this oil for most of the 11 years that I've owned my 2003 Suburban (and my VW Jetta, Toyota Corolla, and Hyundai Elantra -- rest of the family). I have over 100k miles in all of my cars (almost 200k in a couple) and they all purr like kittens. Feel confident in using this oil once per year

I have a 2018 Chevy Impala Premier & Chevy Colorado 4x4 4dr both with V-6 engines. I had the dealer drain the original oil and replace it with Mobil 1 5w-30 Oil. Previous vehicles had almost 325,000 miles each and I only used Mobil 1. I am a customer for life.

The first 600,000 took me 3 motors. On my fourth I switched to Mobile 1 and have almost 400,000 on the engine in it now. Wish I had learned about Mobile 1 sooner. Who do I contact to see if anyone wants to do some publicity on my truck Pictures upon request

i have used mobil 1 pure synthetic for almost 2 years now in my 2011 chevy hhr and have had no problems ,it has now 74,500 miles on it and doesnt use any oil i dont have to add any between oil changes . i would like to start using the high mileage but it is not dextos approved and after talking with a mobil rep i am going to the extended performance pure synthetic .

My wife and I just purchased our own house. So with home ownership we have been thinking about how we can save money one of the ways is to start doing our own oil changes. But after going over the mileage and needing a oil change we stopped in at our local Mobil 1 and was greeted by the manager John who not only had his team give us a much needed change but did it with a level of customer service we thought didn't exist anymore . I am more than capable of doing my own oil change now that I have the space but after going to this clean well maintained well managed location I will defiantly be doing my oil changes there. customer service goes a long way in my book. thank you John and your team.

I have a 1999 Pontiac Trans Am WS6 with 114k miles. I just pulled the motor for some upgrades and I couldn't believe how clean the internals were. This is the first time this motor has been opened up. It's never been cleaned, flushed, etc. It has, however, never had anything but Mobil 1 Synthetic in it. After my experience so far, it'll never have anything else in it either.

I have 345,000 plus miles on my 2007 Nissan Altima se, which was put in when my car first hit 10,000 miles!, this oil is second to no other as my car purrs like a kitten even after running my car with no oil on the dipstick several times, I do not recommend doing that but my belief is if I had anything but mobile 1 in its crankcase, that I would of been shopping for a new car, thanks mobile 1 , jerry b.

My 03 Camry with 2.4L topped 360000 miles this week engine gets the same milage as it did new. The car uses no oil between changes and when I replaced the cam cover gasket the engine was spotless inside. I have used the 5w-30 since the car reached 5000 miles.
