Title: E10 fuel comming soon
Post by: simonst205 on December 26, 2011, 07:58:43 pm

Guys,

I was reading about this on Piston heads

http://www.pistonheads.com/gassing/topic.asp?h=0&f=140&t=870307&mid=0 (http://www.pistonheads.com/gassing/topic.asp?h=0&f=140&t=870307&mid=0)

Will the introduction of e10 fuel cause problems to any of our cars?

Simon

AFAIK we don't have any components in the fuel system which will be attacked. We've had 5% Ethanol in fuel for a while so I'd have expected to notice any problems by now.

The main difference is that the cars will run a bit weaker as Ethanol has a lower air ratio for stoich. I doubt it will be a problem for standard cars (closed loop while cruising and very rich anyway on boost) but may cause problems with aftermarket / piggyback ECU's set a bit too close to the edge.

Going from 5% to 10% can cause problems thought. A lot of cars pre about 93-94 may have problems. There was a list somewhere but I've lost it.

I read this on another form and as far as i am aware the ST185 and ST205 will not have any issues. The ST165 though... not so sure.
