fuel on a 1985 motor?

You don't.

The lead in gasoline was added to reduce knocking. Mixing lube oil in
gasoline for use in a 2-stroke engine lowers the fuel's knock
resistance. The manufacturer designed the engine to perform to
specifications with the use of leaded regular gasoline mixed with the
specified proportion of 2-stroke oil and therefore recommends that grade
of fuel.

Since leaded gasoline is no longer available you will have to use
regular or better grade unleaded fuel that matches the octane value of
the old leaded "regular" gasoline.

Could lead additive affect it's performance? So you are saying I don't
need to add additive, just use a bit higher octane?
