235K miles and still going

I've used this product for 150,000 miles in my Acura TL, the car presently has 235,000 miles on the odometer. I pour the old oil back into the bottle and it fills it right back up to the top. The car doesn't use any oil over the 7,500 mile oil change interval. I use it in lawnmowers, snowblowers, generators, never had an oil related failure. Once I drained this oil out of my lawn mower and forgot to refill it, the engine ran for 5 min with no oil in it. The aluminum connecting rod seized to the crank but no damage to the rings. That's good oil.

What the 5.7 Hemi needed

This is my 3rd oil change on my 2015. I have only 10,564 miles on this truck. And I finally found the oil made for my engine. Three oil changes sounds excessive for these few miles, But I was not satisfied with bulk oil or oil with the name synthetic blend. A mixture of conventional oil and synthetic. I noticed that 5.7 - Liter V8 HEMI MDS VVT Engine was not shifting right and struggled to switch from 8 cylinders to what ever the computer decides is needed at slower speeds. And the proof when I starting using Mobil 1 5W-20 I could tell the difference within 100 miles, The start up tappet sound is gone. my mileage went from 15.9 to 20.6 on the Eco. a gain of 4.7 mpg. And the real proof will be in a month or so the oil change minder should slow down the 100% to 0% oil change reminder. Better protection , lubricating the engine like it should, I have tested this on my other 3 vehicles and found that conventional oil or synthetic blend was not for me. I am finally convinced that my MDS engine was not a mistake.

Seems to still do a good job after reformulation

Been using Mobil 1 for decades. Almost considered switching when Mobil 1 was changed from what a consumer thinks when he reads " true synthetic".....to what the government allows to be called a true synthetic. Have two Jeeps with checkered history's in regard to their engines....an '02 3.7 and an original 2012 Pentastar V6 engine ( before the head mods of newer Pentastars). The '02 3.7 supposedly has an unexceptably high rate of catastrophic engine failure because of too small oil channels...that when slightly gunked up...allows too little oil flow and the early Pentastar engines... which before valve guide hardening in newer versions... suffered from premature valve guide wear and failure as a result of heat and substandard lubrication. Hoping that the high detergent content and above average wear protection and reduction of oil breakdown...to make the difference. These engines will put Mobil 1 to the test

We are confident Mobil 1 is up to the challenge. We’d love to hear from you after Mobil 1 has passed the test.

The only motor oil I use.

I have used Mobil 1 for many years in everything from autos to motorcycles, lawn mowers, snow blowers, firearms, etc. It has generally kept my machines running long and strong. It also lasts at least 2x as long as dino oil. Just make sure to use a proper oil filter for long life synthetics.
