Thread: E10

I am running E10 in my 2000 V8 ES with no issues.. I was running 95 for a while but I cant tell any difference... other than price.

I was thinking of trying it when I finish towing. The only issue that concerns me is the truck is 10 years old now, I wonder if my fuel lines, rubber and seals will be affected....

I thought most cars 10 years or younger would be e10 compatible the fuel line has been around for years and the fuel pipes should be alloy so no problems. I cant use it in the series but do in my vs dunnydore, and yeh cant tell the difference between e10 and 95 except the price

Hi there

This is my take on e10. If anyone knows better im listening. Im definately not a fuel analysing expert but this is my opinion.

E10 is ethanol. Ethanol is alcohol and to make 100hp you need twice as much alcohol than you do unleaded fuel. For example if it takes 5 ltrs of petrol to make 100 horse power for 20 minutes then your going to need about 10 ltrs of alcholol to do the same thing.
The other thing is alcohol mixes with water where as petrol wont. Imagine the 5000 ltr tank under the ground at the petrol station has had petrol in it for the last 10 years. There is probably a few hundred litres of water sitting under the petrol in the tank. This is no problem as the petrol wont mix and the water stays on the bottom.
Next week the petrol station owner decides they are going to run e10 from that tank. Now 10% of that new mix of fuel is going to mix with water and go through your engine. There is now the possibility of rusting the internals of injectors and fuel rails.
I know of people that have done many thousands of kilometers and never had an issue with e10. But i have seen many cars brought in with buggered injectors, rust inside the fuel tank and inside the fuel rail. I could not confirm why they were rusty but the only coincidence between them all was e10.
