I wouldn't worry too much about E10, in such small quantities I don't think it effects the car much at all...

I never noticed any difference switching on my car. *shrug*

Only a 10% mix will me negligible at best with your mileage. If you were running E85, it would only make a few MPG difference (maybe five if that). It burns cleaner and is well worth the loss of .5 mpg.

Kinda of a double edge sword although the GHG are reduce the evaporation on E10 is increased and NOX is increased over 5%. Pick your posion:)

Nox goes up that much? Really now...how odd. You have any stats on propane?

LPG is the hot ticket. I wish it was not so expensive in TX to convert. PM10 fraction of diesel, NOx half of Petro, and VOC 60% less then Petro. Just for you since your google isn't working:p

My lazy is working though! I am really bad at looking things up...

I wonder about running partial propane...would the ECU just compensate and use less fuel? Even 20% on propane would rock...

I think on LPG it about half that. I think that number is for CNG.


Probably should start another thread on this not to get it to OT. But what did they teach you at school as far as GHG and the rest of the emissions story. Should we be putting our primary efforts into reduction of GHG or NOx, PM10 and VOC's. I know, it's not that simple.:)

Start another thread and I'll say what I know, :p

I will get on this LPG business as some point, I swear!

With a diesel engine that was converted to somehow manually feed in propane you would just let off the accelerator pedal, eh? No ECU adjustment of anything... it is definitely interesting.

I'm thinking if you just hook up something based on vacuum but try to limit it to 20-30 percent then it would just let you know how much to let off based on the throttle needed to keep going...*shrug*
