mixing 2 stroke oil

[sheeney]

Hi all
I have no idea what 2 stroke oil I have in my latest bike ...I don't really want to contact the guy who I bought the bike off and ask him what make oil is in the tank ...I know mixing oils is a dangerous game to play ..if I can avoid it I will not flush the existing oil in the bike ...so my question is this what quality oil could I use to top up my existing oil with out a problem ?

Cheers
John

I would take out the bleed screw, drain it out, and put my own choice of oil in there, but;
As long as its a dedicated 2T oil in there and not cassy R etc then all 2T oils blend ok. Don't take my word for that, the tech guy at Rockoil told me its fine to do this.
