Geo:

No harm, I am not taking it personally. I have tried to use facts, instead of hype. I simply found it a stretch to promote E-85, contrary to the manufacturer's recommendations. If you had tested it, and were provided data, that would be interesting. To promote it based on a test on a Ford pickup seems a stretch to me. There are a lot of readers here who wonder if they should just go try it on their BMWs. They are welcome to do so, but they should have the facts, and not hype. They also may want to consider the differences between a BMW engine and a Ford pickup engine. The use of alloys is one difference.

I couldn't see data which you presented that explained your fuel consumption on E85, when it is straightforward math to calculate what the fuel consumption decrease will be, for a volumetric measure. Bringing hp into it is not good science, it confuses the matter.

Presenting information and discussing it is exactly what this board is for. It isn't a closed shop. However, your enthusiasm may have gotten ahead of your data in this case. I am not anti-E85. However, presenting information on reformulated gasoline, MTBF, and oxygenated fuels, and applying it to E-85, just isn't right. Your last post (from an ethanol organization) is not discussing E-85, as far as I can tell, it is discussing replacing MTBE with Ethanol. That is a long way from E-85, which is what the manufacturers are warning about.

Good luck with your ongoing testing.

Edit: I read the link. Good information, if somewhat dated. The paper defines ethanol as a gasoline limited to 10% (what the standard was many years ago). It also gives the figures for heat content, so that fuel consumption reductions can be calculated for various blends such as E85, 85% ethanol. Anyway, it appears to be a sound reference document.
