I found my oil source, and after I clean the fuel tank, I'm going to start running 4:1 RUG/WVO. Summer is ending in Colorado-cool nights, but AM temps in 60s and 70s til october. In SD and other really cold states, they sell a heated grid that you stick to the oil pan and plug in, often in conjunction with a block heater.

Has anyone tried this on the fuel tank,plugging it in at night with a timer, starting car with warm fuel, running all day, and repeat?
