I recently had a long run of over 1000k's round trip. I thought this would be a good opportunity for my first foray into the use of bio diesel and see how it would go in my 92 TD 80 LC.
I was pretty chuffed because the consumption worked out to be 10.6 L/100k on the outward leg, and on the return I had to top up with normal diesel and was towing a trailer so it jumped up to 12.8 L/100k. Quite acceptable I thought.
There appeared to be less smoke, the motor was a little quieter and performance was about the same. The bio I was using is the Gull brand blend in whatever percentage blend that is.
Anyway I ran the next tank down to empty before filling both my tanks again with Bio ready to reap the benefits of cleaner air and slightly less cost. Anyway here is where it got confusing for me. Straight after filling this time with Bio diesel, I noticed a stronger smell of "fish and chips" and at times it seemed to be billowing clouds of white smoke, especially at idle. However when I filled up again on standard diesel, the smokey exhaust returned to virtually nothing again.
Long story short, after many trials and tests and now running the small tank on bio and the other on standard diesel and toggling between, it is definitely billowing white smoke whenever I switch to the bio and when I change back it clears up.
I thought it was meant to be the other way round?? Has anyone experienced this, or perhaps offer some advice?
