What do you guys do with used cooking oil?

[Mark Brenckle]

We save ours to burn in our smudge pot when we're camping

  So, follow the scent of french fries to your camp?  just kidding. Does that help for the skeeters?

I've made a lot of lye soap from old fryer grease.

Haha! Yup!  I haven't noticed a change in mosquitos but it's been great for camping... contained fire and puts out a lot of heat.

I thought about an oil burner for a wall tent stove.  Anybody do this?

My brother did a waste oil drip system for a shop Woodstock. The main problem is how hot it got and the difficulty in regulating the drip. As the oil thins out it flows quicker and needs very refined valves. He used a peacock valve from a radiator and it didn't have precise small flow. Additionally his shop stove was a huge pipe that was roughly 28" ID and 30+" long. The steel was half inch thick and he could get it glowing red. Not sure how a camp stove could not burn you out of the tend or last very long.

I use oil a few times before it needs to get tossed and it also depends on how long its been since I used it. If I haven't deepfried in a while I ll toss the old stuff and use fresh. I store my old oil in containers till we have a fire then burn it.

I reuse mine, leave it in the fryer, try to filter it every now and then.  I've never noticed a fishy taste transferred to other things that I fry in it.  I'll use fresh if I am doing pastries or something like that.  I cover it hot so it stays sterile, never had any go rancid.
