Use your standard fluids, if you think it's necessary run 10/30. I lived in both AK and ND and ND is WAY colder than Anchorage. It's those damn Alberta Clippers! All you need is good maintenance, working glow plug system, a oil pan heater just in case, and good batteries. I would also check the condition of your block heater cord, sometimes they get tugged on or some corrosion. As for your GP system once your relay's spent I suggest replacing it with a
Stancor , or replace it as preventative maintenance (It's a PITA to change a GPR in Nov. in -23 in Fargo

. But you could always jump the terminals with a wrench in a wost case situation.) I went through 2 GPR's in 2 years, then I got this one. DO IT! I'll be moving back to ND in about a year and I just bought a heated Dahl filter just to make the run a bit smoother. But by no means is it necessary. I don't even know how well it will work, saying first the engine will have to consume fuel in the runners and the filter before it gets to the heated fuel. By then the heads should be warm enough to heat the fuel before it's injected. Maybe there will be a difference once I get my RR and bowl delete. All I really wanted was a prefilter but I found one heated for a hell of a deal.
As for tires I ran Cooper Discover ATR's and they are mind blowing in the snow and ice, plus you can run them all season reducing cost big time.
