100% Octain Containing 10% Ethanol

Anyone having any issues with the stock fuel system, while running United e10 100 long term eg. failing rubber components?

You'll want to replace your fuel pump with one which is rated for ethanol, like a Walbro 400L/h

Stock lines should be fine... obviously you'll need a tunable ECU as well if you want to actually do anything with it

Most modern cars are setup to run small percentages of ethanol, your 34 will be fine with it.

My Stag loves the United 100 octane stuff. I've recently went some straight 98 and got just on 400ks from the tank. I get about 440 on the 100. There wasn't any notable difference in the type of driving I did on the 98.

anything post late 80's/early 90's should be fine... and that's for E85, so E10 is completely fine - i changed fark all with my 98 GT-T that ran E85 for years with stock everything, except a drop-in walbro and high-flowed standard injectors. Nothing ethanol specific, no issues what-so-ever and the same for the new owner who also runs it on E85

My car was tuned to 100 octane from united 6weeks ago. The car drives smoother & fuel consumption is the same as when it was on bp98 octane & took an extra degree of timing.
