As Cal Bill says (not the other Bill, hi Bill:-)), once it builds to
any extent as soon as the engine is revved up it gets blown through
with
the transfer of air, there isn't much spare room in the crankcase
cavity
it's all a very close fit.
Ok
The "problem" is that unlike a normal 2 stroke the oil is just raw
oil
& the very small amounts involved at low revs just hang around in
there,
getting overly hot. The overly hot oil bakes behind rings etc just
aggravating an already bad situation.
Doesnt sound good ... is this worse at idle or WOT?
Can one spray anyhing in the air intake to remove this buildup?
The proof is that Ficht had to "recommend" a special high temp
tolerant
oil (read vege oil:-)) & as if needed to confirm it even more E-Tec
has
used "special" high melting point alloy in it's pistons!!!
Veggie oil? Good for the fish
Merc is really obsessed that you shold only use their DFI oil. Of
course one part is that it is like like liquid gold to them.
Theu claim it is because it gets recirculated, which I find quiet the
exaggeration... The only thing it does it flows through the comprssor
and THEN throough the top crank bearing ... I wonder how this is
recirculation and why home depot oil would have a problem with that...
Maybe the real reason foit the DFI oil is the temperature resistance?
Opinions?
They dont want you to use even the best pure syntethic oil ... wonder
why. Just to make money of their oil?
Needless to say normal aluminium melts well over 1000F & petrol will
auto ignite at any temp over 4-500F, so detonation is clearly what
they
know all about & instead of trying to solve the real cause they're
just
"trying" to make the pistons strong enough to survive detonation (&
the
related extreme temp rise) long enough that they will have a reduced
failure rate, such that they can sell a few more till the public
wakes up.
In all fairness I have to say that the DFI motors that are on the
market seem to be holding up well
Thing is I would get a 4 stroke but for a jetdrive there is just no
option to a 2 stroke. And it a lot of fun
Other matter, assuming you have access to a computer that you can
configure a little & you can download (free) any of the good
