Ethanol mix in husky te250

G'day Boy's was just wondering your thoughts on running the 10% ethanol mix in your huskys we have down hear. Only concerned about all the efi pump etc. I run it in all my carbd four strokes because its about 8 cents cheaper its rated at 100 RON it keeps everything clean and i get beter milage. (wouldnt mind makin my own still and runing on 100 % ethanol at say 80>90 proof with some old hondas iv got lieing around very cheap form of transport and keep the environmentalists somewhat happy). I know for a fact you cant run it in RM's or Kx's because it eats the crank seals next time I rebuild them I'm going to enquire at the local skf mob for seals that can.

also what RON are these bikes rated at 95 like most mx's?

your thoughts? (dont real want to turn my efi system into a somewhat rubbery soup lol)

Can't help with the ethonol question, however re fuel it is better to run 98 if you can get it. That said I have had to use 95 on occassion and have not detected any difference in performance on the trail-might be different for an A grade MXer however. The engines are reasonably high compression and do need higher octane fuel otherwise they run the risk of knocking especially if you are lugging etc.

Nice.
Down here standard fuel is 91 octane pure petrol, 95 is premium which is recomeneded for my 2 stroke mxs according to the book, then 98 is supper which I run in my vintages and the E10 (10% ethanol) is 100 octane which I run in my cars boats and XL's and XT's.

The measures used to determine octane rating varies around the world.

"Because of the 8 to 10 point difference noted above, the octane rating shown in the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel. See the table in the following section for a comparison."

Ethanol is getting real common here too- but you can buy 'normal' premium gas in 93 octane yet most places-

I try to run Turbo Blue (115 RON, 110 R&M ) at a ratio of 1:4 with premium just to boost the octane a bit- seams to run smoother or cleaner in general...
