After my run to Ipswich today, 360 miles round trip.
Steady 80mph where motorways allowed.
I can report my meega averaged 25mpg with the air con on.
Seeing it only did 24mpg before (on same run) without the air con on, i think this is vast improvement
SO if you add say 4mpg to the new average to account for aircon being on....more like 29mpg....an improvement thereabouts of 5mpg. [smiley=thumbsup.gif]
For you petrolheads this is prolly about 34/35mpg in petrol terms.
Also tested the cruise on the way back on the m4......it cruised up all the hills without changing into 3rd at all [smiley=thumbsup.gif] (not like before, it used to change into 3rd on most of the hills) so definately power up as well!!
Think I'll be changing the air filter a bit sooner than 65k miles next time
Cheers
Dave
PS Doing the plugs in the morning......this might even improve it a bit more!
