Depends on what you define as "success" with SVO, or even WVO.

There are right ways to run it, and there are wrong ways. The right ways are decontamination, filtration, and heating.

People who do the most damage running SVO typically skip on buying a heated tank. You must heat veggie oil to ~160 degrees F or so. If you don't, you risk injector coking, and eventual cylinder waxing and scoring. This affects all diesels, not just the 6.0L. The problem that people are realizing with the 6.0L, is that the injectors can be rather sensitive at times, compared to say the 7.3L.

Even if you do get a heated tank and run SVO properly, you will still find that a typical engine and injectors will not last as long as one that runs on straight diesel only. SVO does leave behind deposits, that is fact. Maintenance is key to making the engine last as long as possible. You will need to change out the fuel filter more often, as well as change oil more frequently than normal. It is also recommended to pull the injectors every 50K miles or less to inspect them for coking and damaged nozzles. Expect to change out injectors at 100K miles, sometimes less.

The trade off with those who use SVO sucessfully is that if your source of fuel is cheap enough, you will save so much money in fuel that you can buy another engine when yours craps out, and still have extra cash left over in your wallet. Just don't expect many engines running SVO to make it to 300K miles.

my report

been running svo for nearly two years now (Veggiestroke - Classic Series) ...this is my latest report from Blackstone...oil is changed every 5K.

"Wear is as good as we've been seeing so there were no changes this time that would suggest any new problems for
this 7.3L Power Stroke in your F-250. Wear metals are slowly creeping up from what we were seeing back
in 2007, but at this rate, your engine is still on track to have a very long life. "How long?" you may ask. We
would not be surprised to see it easily last 300,000 miles and possibly a lot longer than that. Still no
anti-freeze or excess soot present. Nice report."

i have heard that the glycerine is what forms most of the deposits and causes the injector trouble
