Please forgive me for returning to the topic closed by egnot on 2 November when he lost his way and diverted to the Mazda dealer. I posted this in 'New Members' area as a reply to my first entry, but more likely to get a good flow of respondents here. "We concur on a number of points, not least of which is why Lexus themselves do not address what seems to be a fairly common problem with their diesel engine. It does not compete if fuel consumption alone is the key criteria for purchase, but as you say, it has other great qualities, which is why I have a second one. The main issue I would like to take up with members is the best route to resolve the lack of improvement I am suffering. My plan at the moment is to book it in early for 10000 service (I have 8000 on clock) and ask dealer to check set up; but no certainty of success. Lexus claim the engine has fuel consumption over 10% better than old one. Have any other members with 2009 model achieved this improvement?" Can't understand why the 'new' engine should be worse. Please help me someone.

Thanks for responding on this topic. We concur on a number of points, not least of which is why Lexus themselves do not address what seems to be a fairly common problem with their diesel engine. It does not compete if fuel consumption alone is the key criteria for purchase, but as you say, it has other great qualities, which is why I have a second one.

Lexus claim the engine has fuel consumption over 10% better than old one. Have any other members with 2009 model achieved this improvement? Will also post this to the IS page as I note likely to get better response there.

Hi all. I'm a new member but a 3 year IS 220 driver. Lease car went back yesterday, now have my own 2009 model. I bought it in spite of not being totally impressed by the fuel consumption experience (generally 38ish but up to 50 on the occasional long A road run), but 2009 improvement claims were compelling. First impressions were good (47.5 mpg on computer for 120 mile motorway return home from collection) but real day to day driving is a killer - 34.5 (real) mpg from first full tank and second looks similar. Do I have to change my driving style and avoid stopping at traffic lights, junctions, etc, avoid going up hill or even drive like I need pipe and slippers? Love the car so feel determined to somehow address what seems to be the only consistent thing about the 220 model - its inconsistency when it comes to fuel consumption. Is the IS the only car with so much variation? Cheers

Joined this week almost 3 years to the day after taking possession of my first Lexus IS220d - it goes back to lease company tomorrow. Had to buy this time and decided that claimed improvements on 2009 model tipped the balance against competition. Found this site in search of advice on whether my poorer fuel consumption is common. Will continue this theme under appropriate thread.
