WVO killed this guys TD Jetta

My 6.2 has double the miles that thing did and was more than remarkably clean...it was cleaner than most sbc gas engines I've torn into. A testament to CanmoreK5's good maintenance and running diesel instead of french fry oil.

I have a bunch of 6.2 engines and they are a dime a dozen out here, I will run a $300 engine on WVO if I can save a lot of money.
I wouldn't do it to a new engine that will not take it good. :D

The guy also admits to bad maintainance and abuse so it's not very definitive.

Well, the guy admitted to not doing everything right, especially not changing the oil enough, or filtering the stuff down enough..

the point is, this guy experienced everything that results from running a too thick fuel that leaves deposits upon combustion, and compromises the oil, all of which are things that outfits like the engine manufacturers association, and the department of energy says can happen with WVO use..

It's fine if folks admit these issues can happen, and takes steps to avoid them.. however, what I've experienced is a militiant dismissal of the notion that anything can possibly go wrong with biofuels.. not here in this forum really, but in the clean energy circles I travel in.. I thought the honesty was refreshing, and that his story was a good opportunity to learn..
 
The only thing odd is the turbo fragging. Both the original and the replacement look to have eaten something. To me, that has nothing to do with the type of fuel used. That has more to do with filtering problems (twice even)

The piston damage looks to be a direct result of something being eaten by the turbo and the fragments finding their way through the intake tract. Subsequently there was some pretty piss-poor compression in that hole.

The only thing that appears directly related to WVO is the horribly gunked up valvetrain.

Hi Rene!

just for discussion, here's a link on the subject of WVO in the TDI, both pro and con:
http://journeytoforever.org/biodiesel_TDI.html

Also, Buried deep in the original thread on the tdi forums, , (starting with post 31) the guy speculates that foreign object ingestion killed his first turbo, and perhaps not removing all of the shrapnel helped kill turbo number two..

as for the piston damage, you could be right about an ingested object, but if the wvo cokes everything because it's not hot enough, the hard carbon bits can do a lot of damage on their own..

this guy has sparked a LOT of discussion, from what I've seen..
