Summer/Winter fuel economy
 

I know you don't buy a scoob for its cheapness to run, but once again the switch from summer to winter (autumn?) fuel economy has astounded me.

Driving a MY98 Turbo, totally standard:

Case 1) did 320 miles to a tank, late August (after the rain had stopped, and it was sunny, go on you remember that week)

Case 2) Just managed 240 miles on a tank in mid October...

Again, I know my driving 'style' may have been different in these weeks, but still interested to know if others share the pain?

04 STI
1300 miles old
mixed driving including lots of steady 50 mph gave 245 miles for 55 litres = 20.25MPG Optimax fuel (87.9p)- just swopped to sainsbury super at 82.9p so will see on next tank full.
Not impressed even for a fastish motor.

I've got a 1997 Type R and I average about 27 MPG. Haven't noticed any change between summer and winter.

Wish I could get 320 out of a tank. I've got a MY00 and average 230 regardless of the weather and that's not driving it too hard.

Surely the colder it is the denser the fuel is at the pump?

Also colder=more power which might explain why your economy goes down. Then again I know sod all about it but have also noticed no difference in economy. Car is definitley quicker in colder air though.

I track my mileage religiously on a spreadsheet. 33,500 so far on my year-old MY03 STi. No difference summer to winter in fuel consumption but, as others have noted, you can tell through your bum when it's a cold day :-)

Likewise, not noticed a difference in economy with temperature, but it is definitely quicker in cold air. And I recently did 370 miles on a tank :p (02WRX with mods, >280bhp at PE), and even then it was only ~56 litres to fill it up.

i've been getting around 300 to the tank since i've had my 01 (6 weeks) - filled up today after it ran to empty line at 230miles :-(

Stop fookin worrying about it just do it :hjtwofing

I only ever put £20 in at once cos otherwise I figure I'm only lugging around extra weight that will make it even more thirsty, but generally my Sport wagon (yes, I know its not comparable with all you other lucky folks) has been doing approx 30mpg at 78.9p/l. And that is when I drive it really hard.

The last two fill ups and it's suddenly now doing about 25mpg. Not a huge diff, but still if you do high mileage, its noticable. Plus, if you are poor, like me, it hurts your bank account. :cry: And the cost of fuel in Poole just went up to 80.9p/l so I'm even poorer.
