really flash points haven't changed? Overheating? 2013 andyou cling to 1990's dogma on synthetics....
Synthetics haven't changed since the 60's, except for one or two made and sold in Europe.

I should have said they havent' change much. The synthetics are various water soluble PAG oils such as UCON. And only the formulations and viscositieshave changed. We do not use the increasing number of other synthetics because they will not mix with alcohol.
