iv got almost a gallon ov veggie oil in my cubbord that is expired cause the old lady says we have to cook with canola or soybean oil now cause it has less saturated fat or somthing like that. so its sat there and now outta date, rather than thowing it away can i just dump it in my fuel tank?

 

What have we become....LOL.

 

i'd wait till the summer. make sure your tank is full of diesel to thin it out cause its too thick to burn without it being heated up. post the question on the bio forum. they know alot a bout this stuff
