I am likely to late for the orginal poster but I can answer his question
what is OPE : OPE = Outdoor Power Equipment. and while I am unconvinced
about to much oil causing higher operating tempatures I can not dis prove it
. hpowever if one had a infared tempature reading gun it would be easy to
test. Now on to the other thing
I do know from my years in and around the auto and small engine industry and
that is higher test or grade fuel is harder to ignite ,a good reason not to
put 93 in your car in the winter unless the car is desinged for 93. this
less of a problem since computer and o2 sensors but in the early days of 87
older cars with out computers had to have the timing adjusted to prevent
predetonation; the fuel was more easily ignited and therefore ignition was
occuring to early.
Hope this helps a little or is somewhat enertaining
You do not understand octane and or detonation.
93 does NOT ignite less readily than 87. It is detonation (which is
uncontrolled and un-natural burning) which is the issue, and running
93 NEVER required the timing to be re-adjusted. You COULD advance the
timing on 93 to get more power, in which case running 87 would cause
problems if the timing was not retatded.
Now, on top of that, in 2 stroke engines, oil reduces the octane of
the mixture - and the more oil, the lower the octane - so running
hightest in a two stroke, particularly a high output 2 stroke, IS a
Particularly in today's market, where many fuel companies put 10%
ethanol in the legular and none in the hightest, laving the mid-grade
somewhere around 5%. Ethanol and 2 strokes are notan intelligent mix.
