Biodiesel!!!
 

Are these engines ok to run on this stuff?
Worried about sending the engine to an early grave...

So long as you follow the usual cautions for running any Diesel engine on it, yes they're fine.

One thing i have read is that biodiesel/cooking oil, strips all the accumulated crap from the fuel system so you should replace the fuel filter after a 'running in' period on the new fuel.

Cant remember who not sure if it was bobcat or someone who done a article on this issue...Gareth do a search on forum am sure theres something which is a warning about biodiesel...
