I've always wondered how much water jacket heaters warm the oil. I suspect not that much. So it could matter if a 10w or 15w oil is used.

Never had any starting issues down to -72F, the lowest temp I ever experienced.
And I am sure that warm coolant warms the oil. And would warm it more as soon as it was pumped into a warm block.
But hey, let me check that for you this winter with the Charger (the '06) since it measures oil temp and has block heater.
When I plug mine in the oil temp is significantly affected during winter.
I can't say for sure if the oil has its own mechanism as far as being heated or if it's just radiant from the block heater itself.
the difference was in the neighbourhood of 30c. So if it was -30c a,Binet the evic stated oil temp was 0.
But again I don't know if the heat is just a bi-product of the block heater.
The location of the oil temp sensor will also play into this. If it's in the block, or heads, it will be warmer already from the block heater.
I live in WI. I rarely use the block heater on my truck. There is absolutely no doubt my starter spins the engine faster in below zero temps with 5w-40 in it, vs 15w-40. No oil temp gauge in the truck. Water temp reads 70-80F when plugged in.
I was up north maybe 10 years back with my old CTD truck in -35F temps. The truck sat for a couple days outside not plugged in. When I went to leave, the starter could not spin the engine fast enough to start it. Batteries were both in excellent condition. I had to have it plugged in for a couple hours just to get it to fire. Then it ran on 3cylinder high idle for 45 mins. 15w-40 oil.
Ever prime an oil pump with a drill? Oil is hard to pump, even at 70* F
