What a truly bizarre situation this is.
Surely this would never be allowed to happen in the car world. Its almost tempting to go to the bother of extracting the ethanol using water and a siphon tube, before using it in the bike. I began using premium (low ethanol) fuel a couple of years ago. Contrary to the findings of others, I actually found that both the monster and my thumper ran noticeably better on it. |

'Tis indeed bad, luckily all my bikes have metal tanks (probably rust through instead now).
I use super unleaded in all of them; 916 because high-comp and was tuned specifically for it, Monster because it has high-comp pistons and so favours higher octanes (I know they can tend to pink on lower octane fuels) and the Guzzi because it also is fairly high-comp plus it was built in the '70s in the days of 5-star leaded fuel. It costs a bit more but for my bikes I don't mind paying the extra and I don't do huge mileages either so really a great cost increase.

One thing to watch out for if you do remove the ethanol is octane drop. Ethanol has a much higher octane rating than petrol, (I've read as high as 113), and it's used to boost the overall octane rating of the pump fuel. If you remove the ethanol, the octane rating of the petrol will drop. (I think the overall octane rating drops by about 1 point for each 2% ethanol removed.) Most modern engines require a minimum 95 octane to run safely. Consequently, if you remove the ethanol from 97 octane super, it might be ok but, if you start with 95 octane, there could be pre-ignition problems after removing the ethanol and an octane booster might be needed to bring it back to 95. If anyone's worried or just curious about the ethanol content in their fuel, it's a simple exercise to check it as per my earlier thread http://www.ukmonster.co.uk/monster/s...ad.php?t=54542 |
