Preheating Joe Gibbs break in oil to 180F

Depending on where you live, you could probably just leave the quarts of oil in a hot car parked in the sun for a couple hours.

Or if you have an outdoor bbq with a side burner, pour all the oil in a pot and heat it up like a turkey fry.

I was once stationed in Alaska and in the dead of winter, the gearbox on my Jeep was frozen solid after getting stuck in the bogs the day prior. The oil was too contaminated with water that the engine could not turn it over. Flipped over a trash can lid, put hot charcoal briquettes in and slid it underneath. Changed the oil and I was good to go!
