Hello Guy's,

First time user so not sure how this works,

Bought a Peugeot 407 136hp HDi recently,

Best MPG on a run so far 41 mpg, Manufactures claim 57 on a run.

Anyone else out there had similar probs?

Alan.

There is no need to post the same question twice.

The tests are being made in specific conditions and enviorment, like huw3750 said.

I believe you can't genuinely compare the MPG's that the manufacture claims to the real life driving conditions, there will always be a slight difference.

Ive got a 407SV with the 2.0LHDI engine and i get the same MPG, but i heard that the manufacturer does an estimate from testing on a rolling road, IE no head wind.
