I'm a user of E-85 (my username should explain it), and that's one of the main reasons I bought my Explorer. Here, it's a dollar or more cheaper than regular unleaded, and my MPG isn't all that different. Maybe a couple miles per gallon less, but when you're saving 25 bucks every tankful, it adds up quick.

My oil seems to stay cleaner longer too.

I'll keep using it till it's not cost-efficient to do so.

Regards,
Mike
