My fellow RennTechians...I was out yesterday (actually to fill the tank for some extended garage time), filled my tank and on the way home...fuel line ruptured...again. I am now on my 4th fuel pump.

So my question/poll to all users of high octane gas (I use VP100)...anybody had any fuel pump issues?

Also to those with fuel pump issues...what octane and type of gas are you using?

Thanks much brothers!

We use 98 and 100 RON Shell V-Power without fuel pump issues.

Hi,

Letting a car sit around with high octane fuel is

not good. The high octane eats rubber like candy. I

would burn the high octane out and use high pump gas

for the storage time. High octane gas is fine for

running.

Why does high octane eat rubber? I called the technical expert at VP fuels and he said their VP100 (which is what I run) has the same oxygenators as pump fuel (e.g., ethanol). He said the European fuel lines are not designed for the ethanol we use in the states...problem I have with this is there should be a much larger problem then. I'm with you...there must be something else in the high octane fuel that contributes to this...

I just put in my first tank full of Sonoco 100 oct gas last Saturday and I did not feel a great improvement in power. But, my gas gauge went dead this morning. Not sure if they are related but the coincidence is interesting.
