just to lazy to buy deisel fuel, I know bad to use kerosene/deisel heaters in garages. I did put several vents and couple co2 detectors in and take fresh air breaks. and it has the thermostat on it, it'll get it down to tshirt comfort in but a 1/2 hour not bad for a 2+ none insulated garage.
Best wishes to you Warren how your stroker coming along?
