This discussion is relevant for performance above 10,000 rpm or
for engines that tend to overheat. Such a user needs high temperature
resistance, and this is nomally reflected in the flash point of the
oil, which is found in the Materials Safety Data Sheet (MSDS).
The flash point is the temperature at which the liquid begins to
become volatile or vaporize. The higher the flash point, the
higher the resistance to heat and oxidation. The highest temperature
resistant oils have the highest flash points and contain the most amount of
a synthetic ester. Some 2 stroke oils only contain some ester
and some are 100% synthetic ester based. So, and initial
comparison of some 2 stroke oils looks like this; some
have crazy high flash points for operation in extreme high
heat conditions like racing:
Red Line 2 Stroke Racing Oil, Flash Point 217 degrees F
Amsoil Dominator, Flash Point 201 degrees F
Lucas Semi-Synthetic, Flash Point 182 degrees F
Bel-Ray H1 Racing 100% Synthetic Ester 2T, Flash Point 395 degrees F
Motul 800 2T Factory Line Road Racing, 525 degrees, 100% Ester
Motul Kart Grand Prix 2T, 100% Ester, 492.8 degrees F
Obviously, there's more to oil properties that are important, like detergency, viscosity,
rust prevention, price, and availability, but flash point is a good start to evalauate
an oil for heat resistance. It could be the difference between piston seizures, and
unwanted black deposits, and successful operation at higher temperatures.
