Hello Everyone, Some weeks back my MPG had noticeably dropped i am used to 25MPG on short local runs and 34MPG on long runs, M/Way etc. I have a e-300 td Elegance estate, owned it from new in 1997. Anyway i decided to have the injectors replaced or reconned which ever my Inde decided, it was the latter, recon he chose.
Post the operation i spent a week on short runs and cold weather, lots of stop starts etc, paradoxically instead of an improvement in my MPG i got 20MPG? I measure my MPG, tank to tank so the results are accurate, i am not "crying wolf " yet, and i am seeing what the next couple of weeks brings? The car runs beautifully, smooth and lively etc, all be it i am not one for putting my foot down, i drive sedately sedately on local runs.
My Inde is a top class guy and there is nothing to check at his end, the recon processors are where any faults could be, and it was carried out by a major diesel engineering company, "Merlin Diesels".
I am not familiar with the details of the actual process, if the flow patterns were within their limits, then i suppose they could do nothing to one or more of the injectors, i know the injectors have springs and seals but what the potential is for them "messing up" i do not know? My previouse experience with "Merlin Diesels" was 9 years back and some 100,000 miles on the same OEM injectors, the recon was ok but they did not tighten the boost pipe retaining bolt and over several weeks i gradually lost boost all together, cost me money, time and frustration.
So where do i go from here if the poor MPG continues? I cannot see "Merlin Diesels" letting me or my Inde stand and watch them test my injectors? just may be they might trust our situation and provide us with some new injectors FOC? Do any other members have any advice, which will be appreciated? Herbie.
