WRONG WRONG WRONG !!!!
Vegetable oil NEEDS to be well-heated (~160* is the number that usually gets thrown around) before it goes into your engine.
Sure, it will run for a while until the valves gum up.
I know a guy who was running SVO in his '99 Diesel Mercedes which was unmodified. Ran fine for 8 months, then began smoking on the highway. Shortly after that it would smoke like a sonofagun starting. Then no start. He had to tear it down and found the heads completely coked and the reason it wasn't starting was in two cylinders the exhaust valves were gummed up so much that they weren't closing ergo no compression.
I had always wondered what the deal was with coking the rings and gumming the valves and always wondered if it wasn't being blown out of proportion somewhat but this guy's actual experience now gives me a sort of baseline.
Mike, check out Neoteric (www.biofuels.ca). At this point I've done a few conversions myself and helped a friend of mine with his Cummins & I've dealt with Craig of Neoteric quite a bit; they've got top-notch stuff and excellent support.
Good luck!
