Diesel Mpg In Hot Weather

[buford_t_justice]

For all you diesel drivers out there, have you noticed an improvement in MPG during the hot weather??

 

Mine has increased from 40MPG to 50MPG and I ain't doing anything different. If anything I'm pushing it more with the A/C on almost permanently!!

 

I accept that a warmer engine to start with makes things that bit easier for it to turn over but 10MPG!!

 

I normally fill up every 500miles when the gauge just passes the last white marker, but at the moment I've done 590miles and still have a quarter of a tank left. :ph34r: :wacko:

my mpg has gone down slightly (1 or 2 mpgs)

 

i assume excessive use of aircon is to blame, in hot weather i also leave the car idling for short periods with aircon on, where normally i would switch off. i know its bad, but 35 degreeeeees!!!!!
