E10 - What needs to be done for full compatibility ? in Basic Tech help Posted Friday at 07:12 9 hours ago, paulmanta said: I was being serious... This is what I'm doing. Hi Paul, I thank you for the above post and it does look very straight forward, albeit a bit of faffing around if you just want to drive your car. However, my point was whether we can successfully drive our cars on E10. The way I see it we have three options; 1. Remove the ethanol 2. Find & use E5 or 3. Use E10. Of the three closest petrol stations to me two only sell E10 and the other has promised to keep E5, so I have options 1 & 2 available but can I make option 3 work for me? Is there anything inside the fuel tank that will be adversely affected by E10? I can change all the fuel pipes, fuel pump, fuel filter and now know the injector seals will be ok but is that enough for E10?
