Yet Another Question On Fuel Consumption

[seaside shuffle]

I lovingly have a 2006 IS250 SEL (54500 miles). My question.

Should I expect a reduction in MPG during the winter months. No snow driving involved. air con not used.(to demist screen only) I check my MPG by filling up the tank and 'take account of the 'Trip' total. During the summer months I was getting 30 to 32 mpg, from the past three fill ups this has reduced to 23-25. My daily journey to work is approx 6 miles with approx 100 domestic weekend miles driven. My driving habit has not changed, I allow the automatic gear box to make it's own mind up and drive in a way that I think is conservative (the right foot has a gentle action).

Any thoughts? - Thank you.

In a word...yes. It is quite normal for the mpg to drop a tad during the winter months. I use everything the same as I do during the rest of the year. Must admit I use the a/c, hrw,and heated seats more intensively. I do a 8 mile run to work and currently have 27.6 displayed. Go on a decent run and use cruise and it gets up to 37.

I am getting similar figures to yourself. I don't tend to go too far in the winter months, trips to B & Q, 2mile round trip. Trip into town, this is about 5 miles round trip. Run to Exeter, about 20 miles there and back, Went down the A38 last week, did about 60 miles all-in and averaged as good as 38mpg. I got far more from my 220d but much prefer the 250.

Yes, you will definitely see an increase in fuel consumption during the winter - mainly due to the extra warm up time.

During the summer I average about 37mpg, but during the winter it drops to around 32mpg.
