[s-cars] Octane MTM+1

[Taka Mizutani]

Please be careful with toluene- that's not something you want to handle
casually
(it's a carcinogen for one thing- use a respirator and protective
clothing/headgear/etc.)
and you don't want to go much above 10-15% concentration in the fuel system-
there was
an informal study done on pelicanparts' forum that showed that even viton
seals will dissolve
at 20% concentration.
