First of all, I don't know much about two stroke oil specs, just been reading around; I am posting on behalf of the son of a friend of mine. Specs seem to be VW squared. He has a Eton Beamer scooter that takes JASO-FC grade oil; I had to point that to him and indicated "outboard motor oil" isn't what he should be using. This seems to be a giant hurdle because maybe young people always seem to know more than the designers of the motor... Problem is, I get blank stares when I try to find this oil; the scooter store sells Spectro Platinum fully synth (JASO-FD) but they seem to run out on a regular basis. Last trip they convinced him to buy Bel Ray oil (JASO-FB) The store parts guy said it would be ok to use; I suspect this was a "to make a sale" type of "ok to use"; Will there be any issues using this oil for 1 fill? Curious what other types of equipment take this oil, could I find it @ a OPE store, like an echo string trimmer place? I'm almost ready just to order 6 qts of Amsoil Interceptor and be done with it; Any input appreciated.
