Asphaltene combating it

[Nilao]

I would turn the tank heater off if it has valves. If not, i would drain the coolant and add valves.

Fuel heaters are great in the frozen north or if you have a newer engine that doesn't return heated fuel to the tanks in the winter.

But in the summer i find that the tanks are anle to dissapate more than enough heat to keep the fuel from overheating.

980k and never had a tank off for asphaultine and they're still shiny top to bottom.
