400 for a diesel is a reasonable target.
Make sure you inform the alternative fuel forum on this board too!
If you don't mind the asking here, what's your latitude / zone in the world, and how have you heated the WVO / SVO near and up to the IP, and beyond - using ILH?

It depends of the particular diesel engine.
Below is the compression specs from Mercedes tech data manual. I haven't used a gasoline compression gauge in a long time but as I recall, the gauge tops out at 300 psi, which puts the middle at 150 where the gauge is most accurate, which is on the high side for gasoline engines.
I'm in CT. No ILH. Clean oil is key. I'm more interested in my vaccum gauge indicating VO filter condition than VO temp, I know my VO temp is good. I currently have 20k on the VO filter and the vacuum gauge hasn't moved (5" HG). I switch when engine coolant is 80C.
