will fitting extractors chew more fuel???---what is winter blend?

[Boagie]

hey guys,was curious to ask --do you think by fitting a set of extractors to my n/a 4.2 diesel ute would effect the economy??---i am currently on my first tank after fitting,and the economy seems to have dropped off quite significantly---i am currently on half a tank after only 300ks---my previous tank i got close to 900ks out of!---the vehicle has been unloaded,driven in the same manner also.--i know i should at least wait until the tank is empty--but i just keep looking at my guage dropping.app they have changed the diesel at the servos to a "winter blend"---does anyone know what the difference is and if your economy suffers from it?--any info greatly appreciated:jawdrop:

if anything extractors usually improve economy/power on N/A diesels, not reduce it. I have heard of winter blend LPG, something to do with an additive to stop it freezing up in the converter or something (no expert on these things) but never heard of a winter blend diesel

Winter diesel blend has additives to stop stops the waxing effect.
This is from the BP site


During unseasonably cold weather some diesel-powered engines will experience
difficulties with starting. These problems arise from the formation of wax crystals, which
block fuel filters and lines. This fuel news aims to inform BP diesel customers who live in
cooler regions of the potential problems that can arise from using diesel during winter,
and how to prevent these problems .
WHAT ARE WINTER DIESEL PROBLEMS?
All diesel fuel contains wax. It is considered an important diesel component because of
its high cetane value. Normally the wax is a liquid in the fuel, however, when diesel fuel
gets cold enough the wax starts to crystallize (i.e. solidify). If the temperature is
sufficiently low, enough crystals will form to block the fuel filter and the engine can stop
through fuel starvation
