Yes you can put SVO into a diesel engine, BUT it will feck up your engine.

The central problem in using vegetable oil as diesel fuel is that vegetable oil is much more viscous (thicker) than conventional diesel fuel (petro-diesel, DERV, "dino-diesel"). It's 11 to 17 times thicker. Vegetable oil also has very different chemical properties and combustion characteristics to those of conventional diesel fuel.
If the fuel is too thick it will not atomise properly when the fuel injectors spray it into the combustion chamber and it will not combust properly -- the injectors get coked up, leading to poor performance, higher exhaust emissions and reduced engine life.
'Just put it in and go'
Myth: Just put it in the tank -- any inline injection pump is happy on cold veg-oil, they don't mind starting on cold oil, especially with an older Mercedes.
We hear it every summer, we don't hear much of it in winter though. An experienced SVO'er summed it up on one of the Internet mailing lists:
We agree.
Mixing fuels
Myth: Mix it with diesel fuel or kerosene, then just put it in and go.
Examples:
"I've been running a vegoil/diesel mix, 50/50 winter 70/30 summer."
"I'm running on about 50% petro-diesel to 50% veg-oil, no problems!"
"I use 90% WVO and 10% kerosene as my standard summer fuel."
Responses from seasoned SVO users:
"Your cold starts will begin to deteriorate, your filter will probably start plugging, your injectors will get coked up, setting the stage for ring sticking, glazing of the cylinder walls, increased lube oil consumption and eventual engine failure -- if you can continue to get the thing started in the morning. More than 20% or so veg-oil in the diesel is not a good plan for more than short term 'experiments'."
"Mixing veg-oil and diesel isn't advisable unless you heat all the fuel."

"I am tired of hearing people say that they can dump veg-oil in an old Mercedes, do nothing, and it will be fine. It's abuse of a fine engine, it causes poor, smoky cold starts, the emissions will not be as favorable as they should be, and the starter, glow plug, lift pump, battery, and injection pump will all be subjected to higher than usual stresses."
