Hello Paul,

perhaps the enclosed article is of some interest to you.

Yamaha + Nippon Oil have "tested" some 2 stroke oils in 2002 - the kind of
oil you normally will use for "Premix" ...

They are describing Polybutene as a chemical, that reduces carbon buildup +
it shall be very "sticky", too. So Polybutene is not easily washed away ...
(?)

Especially with SEP carbon accumulation is a (very) big problem.

The "stickiness" could be an advantage for the sliding surfaces in RE.

Lower cooling effect with Polybutene should be no problem, as long you're
not using CCR with needle bearings ...

But I'm not an expert in chemistry ... ;-)


With kindest regards
