Re: HELP! - Freezing temps and Diesel heat (Aquahot) does not seem to start!

Another important issue not raised here is diesel fuel formulation. If you store your coach with summer fuel, and then expect to drive it in winter, you will likely encounter fuel gelling problems. You should add an anti-gelling additive before topping up your tank for storage. The same risk occurs if driving north in the spring to freezing temperatures using southern fuel. It's much better to fuel up in the colder area rather than buying perhaps cheaper fuel in the south.
