From memory, the B40 was 3.5 cents cheaper than straight diesel.
They now sell B5, B20 and B40.
I hope the old thread was lost due to technical difficulties, not spite.
For the record and to replace part of the lost thread...
Since they started selling Biodiesel in January, I have used B20 for 23,000 km of commuting with the exception of 3 tanks of diesel when I had to buy elsewhere. Thats 1300 or so litres. No leaks, no changes, no replaced filters etc. I have mileage records for the car going back about 2 years or 150,000 km all of the same commute. The economy 'hit' going from diesel to B20 was one sixth of 1 percent. The 'butt' dyno didnt notice any performance hit, and the car seems a bit smoother on B20.
I am curious to see how things go with B40.
An interesting note not really related to this: The commute described above was to my old job, 3 months ago I switched to a job closer to home. (I'm saving 2 hours of travel time per day!!)
Old commute: 250km round trip lotsa highway, plus some city
New commute: 90 km round trip, not much highway that isnt stop and go
Old mileage: 5.87 litres per 100 km
New mileage: 6.49 litres per 100 km
So, same car, tires, driver, no engine adjustments, a drop in economy of 10% strictly related to the type of driving.
