In fact many of the tests using veggie oil needed to be stopped due to premature engine failure.
WVO can be run in a properly heated two tank system-IF (BIG IF) the engine is up to temp & the WVO is up to temp (80C/160F+) before switching to WVO. Anything else is killing the mighty Bemz. While the mighty Benz may seem to be running adquately on unheated WVO-a oil sample test, pressure test of the injectors, blowby test, & compression test will show the damage. Do these tests on your Benz if burning WVO-otherwise you are running on bald tires while happy untill you have a flat.
That said -my 16 year old son drives a 1985 MB converted to run WVO. I cannot think of a better car for a young driver then a big, heavy, slow (relative to rice rockets), cold rolled german panzar tank.

If I were running veggie in a John Deere, which I do. I would listen to the John Deere research, which I have.
But these are not John Deere engines.
There is not a single study on the internet, or anywhere else that has shown any harm done to one of the mercedes engines using veggie.
In fact there are lots of people with many many miles on there cars using veggie.
I have seen more and more problems caused by people installing some sort of fuel heating system like you have suggested.
Heating the oil is not really the issue.
High viscosity fuel is.
I have found that using solvents like diesel, napathaline, acitone and gasoline works very very well.
I have run vehicles for thousands of miles for several years now on veggie blends with no problems.
Can you please relate to us your eperience, so we can learn ??
