I newer lie!! But sadly i might hawe wrong sometimes!! I think it was 25 years since the last time..haha! Today i spoke to nr 1 Swedish champ in teaching in ecodrive.. Jan Sörvåg... (Only in swedish....)
http://www.ecodriving.se/vad/arkiv.asp?lev..._02=06&artnr=31 He told me that hawing 2,8 bar instead of 2,2 gives aboute 0,5 L/100 less in fuel when ecodrive... Not when hawing fun,then u just get a faster more stabile car.This could be one reason why my mileage is better than the moast here.haha
But i still think that's alitle bit of skill inkluded too.... And hawing higher press in modern tyres is not going to give u centerweare... But to low press and high speed might give u centerweare as i wrote in another tread... He has 2,8 in his BMW that is recomender 2,2 like the outy... More noice,and stones and cracks in the pavement feles more but on the otherhand the car is more stabile and secure if u suddenly have to turn for anything on the road...
I looked inside my orange box this spring and then i realized that making any changes for the automatic lightsystem was way to complicated for me.. I wanted my foglights to come on at daytime and halfbeam when turning it on... Just to save my xenonbulbs during bright summers up north... But the easiest way was to use my standard halogenbulbs during summer...haha!! But now it's time to change back to xenon and get daylight at night... December-January is allmoast no daylight here. 22 December is the darkest day of the year.100%no sun. After that days slowly get longer... And 22 of Jun is the longest day with sunshine all night...
