You can put a oil pan heater on anything with an oil pan. Generally for less than $75. You only need to have it plugged in when you know you will be using the equipment, or plug it in daily and have it on a timer if you choose. They don't use a lot of power. If left plugged in over night, the heat will rise and help warm the lower block. Combined with a block heater and you will be able to start anything clear to the North Pole in January and have lube to the top of the engine quickly.
I use oil pan heaters on everything with an oil sump I own. And I do use multigrade oils. My question back is, "why would you put an engine thru more hardship than necessary on a bone chilling morning starting it up?" Having warm oil in the sump promotes faster warmup of the engine and lower fuel use. This may not be an issue for someone buying a tank of fuel every two weeks, but I go thru over 21,000 gallons of fuel a year. Heaters, both block and oil pan, can be on timers to minimize the amount of time they are using power. And an oil pan heater costs only the price of a few gallons of oil. I find it amazing that some will put hundreds of dollars of things on a vehicle that does nothing for making it more efficient or improve performance, but will poo poo something as simple, basic, low cost, and functional as an oil pan heater which can improve the life of an engine in cold conditions and reduce overall costs. There are a high number of folks that could do this and are not "land locked" away from a power source. Unless you are off the grid and do not have a personal source of power would one not have a solution available. And I didn't get the impression that the OP was in this situation with the equipment he was talking about.
It just isn't some real cool and hi tech idea and I get the feeling that is why many don't consider it.
