Sorry if this question has been asked previously......I had a look but couldnt find anything
Looking for some advice from you mechanically minded heads out there
I have a 2003 Fiat Ducato (2.3jtd) coach built. It has 45,000 km on the clock and running well.
We were out on the van for the weekend and I have calculated that I was getting 20mpg (14L/100km in new money). The majority of the driving was motorway and we were not pushing any harder than about 100kph
First question is.......does this sound very heavy on juice or is it standard for the 2.3?
Just one thing that might be of note, If the van is running, and you are standing outside, you can hear a "hissing" noise from the engine bay. When we bought the van, we had it checked by our mechanic and he heard the noise......he initially though that it was a turbo issue but having connected the van to diagnostics, no errors showed up for the turbo. The mechanic then put the "hissing" noise down to a leaving vac/air line and indicated that there was no concern
Given the heavy fuel consumption, I am wondering if there might be a problem with the fuel air mix causing excessive fuel burn? (kinda like your central heating oil burner)
Perhaps 20mpg is a s good as it gets
The van has not been remapped and as I understand it, remapping doesn't really effect your fuel consumption rather it gives higher end torque?
