Hi Guys,
Does anybody have any info on the use of Bio Derv in my 1.9CDTI.
Been and had a chat to the local supplier, who says that his product must be used as a 50:50 mix with standard derv (Due to the higher viscosity-any greater would lead to problems with vapourisation), but when being used in this way will give greater MPG, better performance and smoother & cleaner running.
Now the sceptical side of me says that this is a load of bollox and it is just his usual sales pitch.
p.s. I've tried the search function, but Bio is too short to search for!
Thanks
Daz
