Here is what I do when it gets well below zero and I'm starting not only my truck but any engine, I crank it over for a few seconds, release the key and then try again.
It is my belief, and I have no proof of this what so ever, is that it gets the oil started pumping though the engine and then the second try the oil has already started to move.
And remember, just because the oil light is out does not mean the oil is flowing through the entire engine, it has just built enough pressure to turn off the light.
So let the engine run for at least a min before driving.
If you have never lived in a cold climate before, your MPG will be...well...bad, because you have to let the engine run and warm up before driving especially in those extreme temps.
All the fluids will get thick and need time to start to flow, that means power steering fluid, ATF etc..
And I'm serious about people leaving their cars running 24/7, so have a extra key or two made before you go so you can lock it while its running.
And when you do leave it running 24/7 leave the HVAC fan speed on low so the engine can stay nice and warm.
You can have fluids and parts shipped to you, you're not moving to the Arctic Circle, FedEx still delivers in Anchorage.
It would be a good idea to change all your fluids before you go though.

 

Hell, the weather in Anchorage is no different than in Traverse City, we have more snowfall on average. The only heater I use is a cup of coffee while waiting on the thermostat to open up.....

DM's comments made me donate a buck for Alzheimer's research.

 

Well, cold weather on-pavement driving aside, nearest dealer will be in Seattle, so having a care package of belts, hoses, specialty fluids; these could save down time. And the LR3 shop manual on a USB drive couldn't hurt. As for off road, you can get stuck, and recovery folks may not be able to get to you for an extended period. Let common sense guide your adventures.

This video from Shell Oil shows the pour rates at -22F.

 

Exactly, it's not the end of the earth, its the largest city in Alaska.
Sure its not the mainland, but they still have electricity and internet and cable tv.
Park with your back to the wind, use your head and who the hell cares otherwise?
They average the same amount of snow as we do here is Grand Rapids.

Big freaking deal. A good set of all season tires on a AWD or 4x4 and you can get to the grocery store no prob.

I'm going to match your $1.

 

There are more passenger vehicles (200,970) in Anchorage than there are pickups (67,392). Huh, maybe it's just like any other modern city....... -22 aint squat. -30's it's just getting cold.....

You have a better chance of becoming a popsicle in Denver than Anchorage, more idiots per square mile..... no statistic, just common knowledge.

 

I wonder what kind of snow they get in Anchorage, is it light fluffy stuff like CO or is it the wet heavy cave in the roof on Wal-Mart stuff like you and I get?

 

Well, with that Rover, it definitely wouldn't be a year without a Santa Claus; he'd make all his deliveries on a timely basis. But, I think the Reindeer Labor Union would protest that Land Rover took their jobs away. I wonder if Santa needs to crank the engine to get the oil flowing before starting his vehicle up in the North Pole ? He only uses it once a year, no 24/7 running of the engine for him . Just kidding...

 

My omission. I'll start in Anchorage but will also be in Fairbanks and will do some wilderness off roading.

 

On that link that Mike G posted, the shop says they do land rover warranty repairs. I'm guessing they have worked out a deal with JLRNA. They probably stock common parts just like a dealer.

 

Well that changes everything, your LR3 will self destruct immediately and your nuts will fall off.

Fairbanks being interior will get hellishly cold. As far as your vehicle it aint gonna be as bad as those who've never ventured north of the mason/dixon or those loosing their minds think. I know there are companies up there that specialize in winterizing vehicles for extreme cold, mostly Yota's but I don't see why not Landy's. If it's a company move see if they'll spring for it....eh.
