New one on me, funny 'n weird

Occasionally my grandfather tells me stories about placing Lanterns under the oil pan of a vehicle for cold weather starting. Using Kerosene for Antifreeze. Running Tires inside Tires. Tin Cans for Bearing Shims/Spacers on Flathead 6's.

My grandfather even has a Dual Fuel Farm Tractor from the early 1900's that runs on Gasoline and Diesel/Kerosene (Starts on Gas, switch to Diesel, then switch back to gas before shutting it down).

His old John Deere Bulldozer doesn't have Glow Plugs, so what did ol' John Deere do for those diesels? They installed a canister under the seat that holds a can of Starting Fluid (Factory design I might add) with a hose that runs to the intake manifold
