Break in Oils

Some people claim that you can't break in an engine with synthetic oil,or castor oil.

You can seat the rings on a KT100 running synthetic Amsoil Saber at 16:1 in a couple of laps.

Run what ever oil brand & ratio you plan to use in an engine from the very first start.

Fuel mixture is much more important. Run a little rich at first. Re-jet, use partial choke - whatever it takes to avoid running too lean on a fresh engine.

This will reduce cylinder temperatures while helping to wash away the metal particles produced by ring seating.

There is a popular 2 stroke import engine out there with all sorts of break in recommendations. Extra oil, etc.

The factory oil advise about 16:1 initially is ok, as long as you add fuel too.

That engine is a low quality, inexpensive unit.
I have measured cylinders at .005 or more out of round.
Piston rings that only make contact at a few spots initially. No wonder they tell you 16:1 - the extra oil helps seal the rings!

Running this engine at WOT with enough oil & fuel is the best way to seat the rings - and it will still take awhile..

Oily oil is the best.

Oily oil is the best.

Water based oil isn't too bad either.
