G'day Keith, It's Steve Hobbs here. I have only two pieces of reference for my work.
1 - My humble 18 year old Nissan ute that has now travelled 7000 kms on a 40% cold pressed BD & dino diesel mix and appears in all respects to be travelling fine (perhaps even better that fine, engine rattle has substantially reduced, cold starts improved, reduced "smoke", etc..the ute is due to have injectors removed and inspected by an impartial party) 2 - I've had a sample of coldpressed BD analysised for fatty acid composition, which I guess would give an idea of the quality of the fuel by what fatty acids are and aren't present in my fuel. If you could Keith, I'd be interested to compare the fatty acid composition of my farm made cold pressed BD to commercially produced BD to see how the quality stacks up. So, here is the analysis C16:0 C18:0 C18:1 C18:2 C18:3 C20:0 C20:1 C22:0 3.90 4.83 80.54 9.29 0.00 0.37 0.00 1.07 If you could provide me with a commentary on the quality of my fuel, it would be appreciated.
