Switched to M1 5w20 for this oci. My gas mileage has dropped by over 1 mpg and getting worse as the oil ages. Had been using Motorcraft 5w20 blend. I'm switching back.

Unless it magically changed into 20w60, I think you have other issues.

Too many uncontrolled variables to conclude anything; tire pressure, atmospheric pressure, wind, fuel forumlation etc etc etc.

OCI is about 4k. I keep very close eyes on tire pressure. Just seems like its the oil, I could be wrong. When I switch back MC, I'll know for sure.

Oh, and if you're dumping your oil and changing the filter ealier than you would JUST to get the M1 out, you'll be throwing the cost of those miles left in the OCI down the drain.

My truck will get better fuel mileage on MS5k or MSS than any other oil. people can choose not to believe me, however i drive the same route at the same time of day 6 days a week at the same pace checking every fill up. i will get .7-.8 mpg better with MS5k or MSS, i swear to it.


I love mobil 1 3 vehicles in my driveway have M1 5w30 in them right now, but honestly the fords ive owned including a supercharged mustang GT ran quieter and better on the Motorcraft 5w20 than M1 5w20.

I've seen a LOT of people make that comment about Super, you're not alone.

A lot of complaints about M1 and noise too...doesn't mean it's not working well but I don't like noise either. Rumor has it the AFE versions are quieter.

Exactly!

It's winter now...winter fuel formulation, longer open loop operation, more warm up time, etc...

My 5.4L doesn't seem to care what is in the sump shrug I've run everything from D1 5w-40 to M1 5w20 in it (and a pile of oils in between, like Redline 5w-30, PC 0w-30, M1 AFE 0w-30 (current), AMSOIL AZO 0w-30, PC Duron-E 0w-40, M1 0w-40) with no discernible difference in fuel consumption.

Too many variables, flawed experiment.

When i had my ford escape, i could not measure any fuel mileage difference between 5-20, 5-30 and 5-40. So i don't believe there would be any fuel economy differences between brands of 5-20.
