what kills a business is supply and demand. Diesel is $2 per gallon and the conversion is > $1000. The initial investment is too high, too much hassle to collect the oil, too much work to de-water and filter the wvo. All in all, it is not worth the investment and the hassle. It is like the sale of Prius is way down also. I bet my top dollars the interest will be there again that when diesel goes back up to $3-$5 range.

There are owners here who detest WVO but I am not one of them. I run my MBZ on WVO without any problems for over 20K each on my 300D and 300SDL.
