Has anyone on the list experimented with synthetics to lower oil temp? I understand that some are approved, including Amsoil. Pure synthetics have no crude oil base or paraffin, to crystallize behind your rings when temps go the the 200 degree mark. They reduce and in some cases nearly eliminate friction (heat). Plus the way most of us fly, the aircraft can sit for long periods of time without the need of an oil change, or "pickling". Up to one year without a "dry start". I've tried it in the family car and in our "greyhound" type bus motorhome conversion, with astounding results. 25% increase in power and fuel mileage, and have just changed the oil ( the first in three years and 30 thousand miles). My oil analysis still showed a TBN rating of over 13 points,( thats the lubricity rating) My former ratings on the petroleum products were at the 4-5 point level after 5000, miles. I really didn't have to change, according to the reports, but I '' chickened out". The only problem I have, is that in the fall and winter my engines run too cool for proper combustion,critical in a diesel. Aircraft turbines cannot run without synthetics. Should tell us something--eh? Doug P.S. you've got me thinking. I'm calling Amsoill in the morning to see what they say.
