I guess I'll have to see what it would take to heat up the oil pan with one...

Portable induction cooktops to heat up the oil, it's just amazing the ideas this site generates.

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.

I think the idea is great.

Title for the thread. "How to cook your way to better MPG"


To warm the coolant a ferromagnetic material sleeve could be added to the lower radiator hose and a unit attached there.

Rubber might get nasty if it gets too hot.

wow, i guess i need to delete my oil cooler, or maybe just relocate it inside the engine bay for winter.

Just cover it. Even something like tin foil would work.

I believe this myself and have said it before with little support. As you say the oil comes up to temp so slow and the head is where the combustion is so it comes up fast.

Just acedotal but my mom lives on top of a hill and there is a huge noticible difference in engine braking (& injectors off) going down that decline on a just started engine vs an up to temp one. The only factor involved is oil viscosity.

I see it on my scangauge too, air temperature is irrelevant on my idle fuel economy, its all coolant and oil temp, I did see a difference too when I changed oils from summer to winter oil.

You might also try a thermostat in the oil line to bypass the cooler until the temps are getting up there.
