Hope your oil isn't jello at that temp. :surprised:

starting is not an issue as long as the battery is fresh, the issue with cold weather starts is the time it takes the oil to flow to parts that need constant lubrication, the slower the flow of oil increases chances of wear. But what I'm reading these days it better to drive the vehicle after starting to warm it versus letting it idle for 10 minutes....

I run full synthetic so it shouldnt be.
I run full synthetic in all my vehicles as well but for the cold the most important factor is the low temp viscosity (the number before the "W"). 5W20 is better than 10Wx at lower temps.

I'm thinking maybe a heat lamp under the oil pan as a temp solution. Could also do a blanket over the engine compartment to keep any heat in. I don't think it would take that long to warm the oil up a bit.

I got a block heater from the dealer and did the install at home. It’s quite a bit of tear down, but ultimately not too hard. I also installed two heat pads—one on the oil pan and one on the transmission. All three run to one plug at the front. The pads were easier to install with RTV, but I always feel the block heater is better. Also change the coolant and think I’m running 0W20. This worked for our Grand last winter and seems to be holding up with the JL, too. We’re having long stretches of —40 here in AK, but so far, no issues. $100 and about 2 hours, and you should have a block heater in.
