I have been using Allion 260 2012 for more than one year now and it has been giving bad economy since the purchase.I have done all the maintenance- engine tune up,replaced all spark plugs with originals did all the services regularly.
when I pump fuel for Information display shows a certain predicted range like 500km
My car gives ONLY 2 types of fuel consumption
1.for every 1km on the predicted range car only does 0.5km-so only 1/2 or less of predicted range I get-ex-200-250 for 500km average around 8-9kmpl regardless it’s traffic or highway ,this is the pattern 80% f time
2.occasionally car does 2km per predicted 1km
so gets the predicted value or my calculated range
Usually this happens after driving more than 40km/h steadily for >10-15km
so what can the problem?
is it a programmed kind of thing with cars electronics?
how does car only exactly runs on those “settings”?
I’m confused and it’s gobbling up my money for fuel and I can’t fix it or couldn’t find a person who knows what to do
thanks
Thanks for your detailed answer I do drive in both heavy traffic and open roads regardless of that and regardless of whatever the capacity I fill in ,only way that car economy goes is according to the “equation” I mentioned above which is 0.5km per 1 predicted km which seems very strange I’m happy if I can get 10kmpl but actually I have never got it up to now I’m not a heavy footer or don’t pulstate the pedal It has been fitted with 121 ac compressor when I bought it but rest are in very good condition I value any other expert opinions thanks
