Helps maintain fuel mileage and and extends oil change interval

250,000+ miles - Still Going Strong. I have only used Mobil1 products in the vehicle.

Does the job very well works as stated longevity of oil is more than efficient

Good good good good good good good good good good good

I always used Mobil 1 until I started watching commercials and reading reviews about Pennzoil Platinum and how better it was. So I used it and it made my engine sound really loud and the RPM's high. As soon as it was time too change the oil I went running and got Mobil 1 Extended Performance 0W-20 and thank God I did. My engine is back too running nice and quiet. RPM's are back too low. And my car is back too running nice and smooth. I will never cheat on Mobil 1 ever again.

Have a 2015 Corolla ECO with the CVT transmission with 4,000 miles. I had the factory oil changed at 3,000 miles at the Exxon-Mobil station. This vehicle MUST use 0W-20 synthetic according to Toyota. There is now almost no engine noise and fuel economy is about 44 mpg on the highway.

Don't know what a group IV PAO is? Google "Group IV synthetic motor oils". Check out the SDS (Safety Data Sheet) from Mobil on this product and you'll see it's ONLY the 0W-20 Extended Performance (Not the Advanced Fuel Economy) that has 60%-70% of the homopolymer 1-decane. The same product line, Mobil 1 Extended Performance 5W-20 doesn't come close to this high percentage of Group IV PAO. Why does this matter? 1-decane is made as a 10 carbon chain polymer that is truly man made which means a more consistent molecule size/shape running through your engine. Pairs well with the Mobil 1 Extended Performance M1-110A for my newer Hondas. Why 110A versus 110? 110A was redesigned to extend filter life to 20,000 miles from the 110 version which was protection to 15,000 miles.

I am a millennial with a passion for automobiles, and a deep background in the auto industry since childhood. I keep my car in perfect condition and I know that with proper maintenance anyone can get 200K miles on most any non-turbo engine. The biggest part of achieving that mark is getting the best oil you can, and changing it at the manufacturer's recommended intervals (regardless of how long the oil manufacturer says it lasts). This is the best overall product for your engine. Oil is only as strong as its weakest link, and Mobil 1 covers all the bases.

I have been in charge of two different fleets at two different Sheriff's Office for the last 26 years and ALWAYS used Mobil 1 EP in every Ford Crown Vic, every PPV Tahoe and every single GM we have ever run. I cannot even imagine how many quarts, but thousands for sure and NEVER ONCE HAD AN ENGINE FAILURE! Change every 5K because of severe driving with Mobil 1 filters and have NEVER had an issue!!!! Will continue to use without question for many future oil changes!!!

I found I spend less with this quality oil than I would on regular oil, which I would have to change every 3 thousand instead of 10 thousand miles. All the couriers I know use this oil in their cars, otherwise we'd be changing oil every 3 weeks or less (I drive 1000 miles a week). This oil really lives up to it's marketing. Very happy so far, my Prius runs as good as the day it was new.
