Draining and concentrating fluids
Been pondering this for a while.
If i drain the extra oil out of the engine i need about 1.7kJ/K less energy to warm the engine. If i concentrate the coolant from 50% to 75% that's another 2.4kJ/K.
Going from -20⁰C to 85⁰C those two mods should save me 430kJ!
That should speed up warmup as much as having an 800w block heater plugged in the first 9mins of driving.
(Assuming 1L of oil drained and 3L of coolant in the engine.)
