E10 fuel in a late C4?

[Lankybloke]

Hi all I have a '95 LT-1 C4. Do any boffins out there know if there'll be any problem with using E10 fuel when it's inflicted upon us later this year? eg fuel pump, fuel lines/rails, injectors, oxygen sensors or ecu re-learning?

The general opinion from the Federation of Historic Vehicle Clubs and other bodies is that any pre 2002 manufactured vehicle will be affected by current 5% levels , and obviously more so when it goes up to 10% ethanol .

Is there a specific additive to negate these effects?

I already replaced my fuel lines with ethanol proofed rubber a few years back and rebuilt my fuel rail with silicon greased o rings and also fitted a new diaphragm to the fpr, ..again, covered in silicon grease which is one vital product in my toolkit I'd never be without.

I send details of an article I found recently on the subject to the Editor of Vette News, too late for the current issue I think but maybe in the next one. Anyway, it seemed to be saying from C4 onwards they are OK. I think it was from one of the insurance companies but I can't remember exactly. I have an early '86 C4 and remember that and my C6 were OK according to what I read. The FHV probably does not specialise in US vehicles, which may be thew reason for some confusion.

We've got the E10 over two years now here in Belgium and I've always been a petrol driver. I use the E98/E5 gasoline for my cars and the '88 C4 can use it without a problem.

I've changed all sealings and lines from the C4 before even E10 and E5 became standard.

You can buy ethanol killer to drop in your tank, but I use this only when I store the C4 during the winter.

Millers Ethanol additive and Frosts Ethomix are both approved by the FBHVC . The topic has been covered in other posts on the forum .

Thanks to all for your responses. Wikipedia (Ethanol fuel in the United States - Wikipedia) says 'As of 2011, most of the U.S. car fleet was able to run on blends of up to 10% ethanol', which I think is ambiguous (does it mean the entire US car fleet that was on the road in 2011? Or just new models from 2011?) hence this post in a quest for some clarity. Both my Corvette and my '90 Chevy pickup run perfectly on the current E5 with stock fuel systems. So the idiot in me says 'will another 5% ethanol really make any difference?' while the (much smaller) non-idiot side says that it's doubling the ethanol content so I'd better start doing some digging.
