Re: 159 1.9 JTDM Fuel Consumption
Looks as if I've joined the 159 1.9JTDM shockingly bad fuel consumption club. I filled my car up yesterday and was shocked to discover that the last fill had been disappearing at the rate of only slightly better than 30mpg. Winter admittedly, and a few more short journeys than usual, but pretty dire all the same, my car has averaged not much better than 34mpg over its life according to the computer, and I've only seen just over 40 once during a leisurely French touring holiday, and that was on Total superduper premium extra special diesel fuel, the exact name of which I can't remember. As I passed Meridien Bournemouth later that day, I called in for a chat with Service Manager Rob and Salesman Oliver. I told them it was going OK, and not smoking or anything like that. Rob came out with the "Alfa claim 47mpg average" line, and couldn't come up with any explanation for the way my car is drinking diesel. Oliver has offered to lend me their 159 1.9 demo next Friday to see how that performs in my hands, and they'll take a look at my car at the same time, though I'm not expecting them to find anything wrong with it. My last car was a Saab with more or less the same engine, and I usually got something between 40 & 50 out of that, and before the Saab I had a 2 litre petrol Audi A4, which averaged something in the upper 30s. All were driven in a similar manner, so why is my (otherwise lovely) 159 so awful in the mpg department? How do these cars manage to slurp down the amount of fuel that they do? I've seen claims here of 40+ averages, and I defy anyone to get anything like that from my car. If there's anything to report after next Friday, I'll post it here of course. As I said, my Alfa has pretty much the same engine as my Saab did, and Alfa's advertised consumption figures are significantly better than Saab's version of the 150bhp 1.9. Both cars have led very similar lives, so I just don't understand why my Alfa 1.9 drinks fuel at a much greater rate than the Saab did while travelling at much the same speeds in the same conditions on the same roads. It's done well over 10,000 miles now, and there has been no real change from new.
