Are you sure there is no 95 Octane in Chiang Mai?
I was told by a reliable source that Caltex 95 maybe more than 95 more like 97. This from a guy who races Motard here.
Shell a likely candidate as well.
Ah I get it you want to carry Toluene around in your pocket to top up the 91 in the villages

I'm not totaly sure but Petronas has it in Chiang Mai , on the way to Doi Saket i thought.
Thats were i filled up my Honda XR for the last time with 95
Cheers
It seems incredulous to me that 95 is not available , however.
Has your bike been modified from stock? Does it say anywhere on the bike that it needs 95?
If you think it needs it and if this information is correct Toluene has an octane rating of 114 and the formula is :
So you need to carry 2l to the gas station to fill up! If you are racing that is different and in which case why not ask your fellow competitors.
Have you been to Home Pro or your local hardware store and looked in detail at all the paint thinners to see if any of them are Toluene?

Question to self: Why am i bothering with all this?
Update : According to my knowledgeable friend. Toluene from the refinery is about 200 baht / litre. So to make 12 litres of 95 will cost 400 plus 10l at 3x baht = 700/2 = 58 baht/litre. Are you really sure your bike needs this?

To get 95 from 91 you need to run at least 20% which gives you 94.8.

Might be cheaper to go to the airport and see if they have any AVGas.

That's some reply Mike are you a Maths teacher :lol:
KTM recommend a 95 RON, which is the most commonly used guide to octane rating.
Does it need to be 95, can't say for sure but more octane up to certain point is never a bad thing, particularly whem thats what the manufacturer recommends.
Your calculations are spot on, it's a simple mass balance equation but I'd be happy to give it a boost to say 93 with 10% Toluene. Some places quote Toluene as 121, but as you say 114 is more accurate.
Apparantly in Arizona / Colorado all the guys can get is 91 RON so its not the end of the world, but as I said more is better in this case.
Bike is KTM 300 2 stroke.
I'm back to CM in a week and will go a a hunt for the stuff then
Cheers Daz
