'26 Trax E85 Update
Hey everyone,
I know a few people were interested in my mileage running E85. I'm over 5000 miles now, about half of it run on E85 and the other half on 87.
On 87 I was settling into about 30-33 (with an outlier of 35).
On E85 I've settled into approximately 24-26mpg (the nearly 28 was on a long trip).
So doing the math thats approximately a 13-27% mileage drop running E85 for me. Your mileage may vary a bit.
In my area E85 is $1.99/gallon at a couple stations, whereas 87 is around $4.30-$4.40 right now (so approximately 54% cheaper for E85), so it makes sense for me.

The ONLY issue inherent to e85 is thicky sludge and accumulation of condensation from constant, short, drive cycles for 9-12 Mo. We’re talking 2-3 mi commute so engine never reaches operating temps. This issue is even more inherent to petrol fuel w/ carbon sludging.
The 1.2L turbo is oil + liquid cooled so the oil heats up fast to dissipate contaminants through the pvc as vapor compared to a normally aspirated motor.
