Great post Piwoslaw. Really impressive stats there. I guess the wide range of temperature rises must be due to wind speed?

I just recently installed a 2kw coolant heater with pump. It's fine, but I was thinking of adding a small pad heater to the oil sump pan to get a more even heat distribution, and because with just the coolant heater my coolant temperature drops immediately by 10 degrees C as soon as I start the engine. I'm assuming this is due to the cold oil hitting the oil cooler (oil/coolant heat exchanger).

But 250w or 125w? I can't decide. Which do you think would be better? I was going to go for a conservative 125w pad heater but perhaps if it is being switched on at the same time as the coolant heater for an hour or less, then a 250w heater might be better. What did you find? Do you find that a 125w heater is about right for you?

I also have a diesel - a 1.9 litre VW TDi - but perhaps you are in an area with colder winters?
