Anyone have experience with M1 Advanced Fuel Economy improving MPGs? If so, what difference are you seeing?

Depends on what you are running before you install AFE.

If you are using an ILSAC 0W30, or Mobil's own M1 5W30, you'll measure nothing.

If you are using a 15W30, you'll get a couple of percent.

Given the myriad variables in everyday driving that overwhelm the much smaller effect of the oil, you will never see it. It is there but it is far into the noise.

An article I linked once showed that the energy density of gasoline varies by up to 4% even at the same station. That is much more than what the oil can affect.

If you are lucky.

FlyNavyP3 just ran 20W-50 in his Lexus, fuel economy didn't change any appreciable amount.

Very hard to get scientifically measure it because variations in wind, elevation changes, and speed mask the results . However, it’s been well proven on dynamometers and they they are comfortable advertising it as such. Don’t expect anything over a few percentage points.

Marketing at its best. Still, it’s a good oil. Just don’t expect to see any gains in fuel economy.


Cannot see signatures any longer so it doesn’t matter.

I measured between a 0.5-1.0% loss of fuel economy switching from a 5w30 to a 20w50 averaged over 5,000 for each OCI. Not scientific as there's the issue of getting the tank exactly the same fill level over each fill up but averaged over 5,000 miles each time helps to increase the data points and reduce error. Even still 5w30 to 20w50 was about 0.3 MPG on a 26 ish MPG average car.

When I first bought my 2007 Ford Fusion I used M1 5-30 for two 10K OCIs. During that time(about one year) I made two trips to my sons home in Florida(900 miles one way) and it's Interstate hyw all the way. I run right at the 70 MPH speed limit. My MPG varied from 30 to 32.5. After changing to M1 0-20 my mileage has increased to 31 to 33.5 for the last 19 trips to Florida.

I'm running AFE 0w20 in the Pilot now; no difference. Also ran it last summer; no difference.

On another note, I notice the valvetrain's a little noisier with this stuff hornets

I didn't like it in my Matrix. Seemed thin, and didn't notice a significant MPG increase. Castrol Edge HM 5w20 seemed to net just as good MPG without the chatter.

Your engine broke in and quite well too as your history shows.

I’d say if any it would be minuscule.

Way less than tires, weather, etc.

Best mileage in my Camry (non-hybrid, 2.4, stick shift) of 34 MPG delivered in May/June on AFE 0w30. But-but-but it was within the static between tanks. Dumped that AFE for some summer weight shortly thereafter but started using AC which pulled MPG down.

I was only running it b/c I got it cheap at AZ.
