Thanks Fahad, I think I will stick with 0w30 oil.

I'm also disappointed with the 2.2 I-DTEC MPG in my '09 Accord EX Auto.
Am getting 33MPG. 
Mostly Town and occasional 20mile round trips, but was expecting better.


I've just changed my Air Filter, and have reset, and that may help.

Also, am due an oil change, so will ensure fully synthetic 0/30 is put in and see if that helps.


I find less use of the 'lead foot' helps.
I notice in the mpg display that when driving, if you get up to speed, then drop the pedal back a touch, you get improved MPG,
so am in the process of training myself to drive a bit more 'softly;n :)

changing the air filter to a proper honda one has my mpg up from 33mpg to 39mpg, even hit 41mpg ar one stage.
Amazed at how much it has inproved.

That would explain some of it. Milder weather is more likely the reason for improved economy on a diesel.

My 2010 idtec auto saloon has now done 101,000 miles (70k with me) and as far as I can tell between fills is doing 45mpg and around 50mpg on a run as it always has in the past five years. However, I don't trust what the computer tells me any more. After a long motorway run it says I have averaged something like 48kph (I'm in France). I wonder if there is some way of resetting it?
