Hopefully it won't cook the oil.
Since induction heating is so efficient...one would expect it to outperform the standard radiating coil types. Looking to find a broken induction top so I can strip it down and embed the coil on the outside of the oil pan. Place a rubber mat between the element coil and the pan to keep the vibration from destroying the element coil. The only problem would be is that the control panel doesn't allow fer auto on when the power is plugged in so using a timer to start it might be out of the question. I'll have to do some brainstorming to bypass that some how...maybe a relay system. Who knows.
I'll have to do an experiment to see how quickly the oil will come to temp. Maybe an old oil pan filled with 5 quarts of motor oil and placed on top of the induction burner. Time how long it takes fer the oil to hit the upper temps and when it starts to level out. Maybe sample the temp at 2 minute intervals along with the ambient temp.
If this works...could you imagine using an induction heater setup on an iron engine block to preheat the coolant? Even something like an iron reservoir that was plumbed into the cooling system might work, too.
