At work about 20 years ago they tried vegetable oil based hydraulic fuild with the thinking of it less costly for any clean up issues , to me it seem as it got hot from use it left a think film on the cylinder rods ( think of a Fry Daddy ) and in time damaged the seals , we had so many cylinder go bad , hyd. tools ect. we ended up swapping it out for regular hydraulic fluid , but for  the fun of it give it a try , Al

I think that the vegetable oil will break down fairly quickly. It will lead to engine failure. I may be an interesting experiment with a mower engine to see how long it will work. Making a biodiesel fuel is an interesting idea if you have lots.

That's what I like a person willing to take a chance, like you said give it a try. The heat would be your main concern and if used for a long period of time, then the interior of the motor would have to be checked to see how it was holding up.

You could be opening up a can of worms, but it would be worth researching and experimenting with.

From watching cooking shows with the wife, it seems that vegetabe oils made from various products have different temperatures where they begin to burn. So you might want to investigate that and look especially at devising a method of checking oil temps while the engine is operating. And the Flash Points of the oils. It could work or go "up in smoke"? Don't be afraid to experiment, I think it was Thomas Edison who said he had Not failed, he had found 1000 way not to make a lightbulb. But eventually he did it and the rest is history.

As said before, it may work a short time. In petrol based oils you'll find additives. Vegetable oil will burn down and the grease is gone. I can better explain it in german :smilewink:

There are successful bio-based engine oils out there, G-oil being the first one that comes to mind. However, the starting "bio" stock is really just used as a source of carbon chain molecules to be ripped apart and put back together as a synthetic oil. G-oil actually uses beef tallow as their starting point.

Research this first before wrecking a good motor. This has probably been done many times. If so, you want to try adding to that research in some way by performing a different experiment instead of repeating what's already been done.

One thing to remember is cost,

  difference between a gallon of cooking oil vs: motor oil isn't worth the damage that will happen, sooner or later.

I'm sure you will do just fine.  Take some deep breaths just before it's your turn.
