Ok, so do you guys wire the heaters to run anytime the key is in the "on" position or do you guys have a switch?

I wouldn't mix the diesel and oil outside the car. I wanted to maybe have 2/3 tank of diesel then top off with WVO or SVO (you get the idea).

If I went the heater route, would I want to heat the tank or fuel lines?

Thanks
David
