TD5 fuel consumption

<< < (2/2)

I drive like I have the pope in the back and get around 35mpg  Which I am well impressed with, its 100% standard and got the EGR  fitted.

I've noticed in the past TD5 engines seem to fall into two distinct distributions, those with reasonable fuel economy and those with disastrous fuel economy.  (Mine falls somewhere between the two but I think it's the tyres and all the extra air resistance.)  My pet theory is that there is some little-known problem that plays havoc with the fuel economy, but I've not yet worked out what it is.  Sorry this isn't very helpful, but I'd be interested to know the solution, as it shouldn't be that bad!

For an unmodified auto I'd have thought 26-28 at worst.

On a long run - Manchester to Kent at a speed of 60-70mph I will get around 35mpg. The same run driven enthusiastically then the mpg falls to 25-30. lots of short runs gives an mpg in the mid to low 20's.

If one or more of the tyres is low then the mpg falls below 20mpg.

The reason I mentioned binding brakes was that the mpg on mine was crap and I thought the brakes were binding on the drivers side.(heavy braking and pulling to the side symptoms-down to tyre pressure or so I thought)  They weren't and I didn't investigate further. Turned out (at MOT time) that it was the passenger side that was binding and no I don't  know why it was pulling to the right either. My D2 is an auto so you don't get the other symptoms associated with binding brakes like a burnt out clutch

Cheers
