Who's making their own diesel or running the used cooking oil? I'm curious as to what kind of problems people have experienced running this. Also can u switch back and forth with normal diesel or mix with normal diesel?

 

I had a 4BT and ran WVO in it for about a year with no troubles at all, right now I'm running it in my 85 MB 300TD and my 93 Dodge 6BT, I've been burning WVO for 5 years now, the only trouble I've had so far is with the Cummins 6BT VE44 pumps not wanting to idle after a while using WVO. Lately I have been mixing more diesel with the WVO. Its funny, I ran strait WVO in my 4BT for over a year and never had any issues with it also ran it in a Isuzu 4 CYL 2.5 turbo diesel for over two years with no problems. You can mix WVO with diesel, I'm running a 70% WVO to 40% diesel now.
