How about Dow's Syltherm HF good from -100F to 500F

Or Syltherm XLT good from -140F to 500F?

The only thing I am not sure of is if they may be used in an engine - you should contact them for that:

Ther are plenty of heat transfer fluids, but may not be practical in an IC engine. Talk to Dow as stated above or even here.
