first "reliable" result of this year... temps are getting slightly better but not the milage... i'm running a grillblock for the topgrill wich doesn't seem to help much, and recently i noticed on of my wheeldams has been broken off... i think i'll revise these once more

estimate based on what i remember 7.7 l/100km and the data about the previous and next tank
recovered the data while moveing (forces you to go trough all your stuff) still my guess was acurate and the milage is bad
combination of partial fillup on 01/17/09 and full fillup on 21/17/09... virtual average of these two filups
somethings needs to be adressed... the car has been returning a crap milage these last months... might be the cold, but i'm not happy with my results

big wheeldams that curve around the wheelwells on the inside in place, side undertray removed
car feels very good on the highway, although maybe a bit light at the front...

freezing cold, day and night temps don't go above freezing, it's been about -1 to -9 celcius all the time, so FE and aero are on the backburner... i'm glad the car will start in the morning. it's disapointing this last fillup of 2008 is the worsed ever, but on the other hand fuel prices have gone down... that's no excuse for bad FE but it does make it less of a real problem. anyway.. lets hope FE will go up again in '09

not to happy with the result quite some experimenting and bad weather over this tank. i've taken off the rear strakes and revised the wheeldams although i'm not sure if they're ideal yet. after this fillup i've put the rear wiper back on, as the weather calls for it

colder weather experimented with sideways extended undertray and various wheeldam and grillblock versions not to happy with the results so far but cold weather and a lot of short trips might have a part in this.

some grillblock setup experiments; installed lower wheeldams along with the original's to form a big dam near the end of this tank, also ran a few lites of diesel contaminated fuel , but since i don't know how much, and it seemed to have canceled itself out it's not included here... i don't recomend it however

aluminum undertray in place for more than half this tank about 15L in stock config + 30L with full undertray minus wheeldams. i hope my next tank will bring me around 40mpg
planning to redo the wheeldams, but a little lower bit brake cooling ducts above them, like i've seen on some VW's next on the todo list is an active grillblock for the top grill

1st 1/2 tank... filled op with about 60L of 95ron the 1st time and now refilled with 28L of 98 so that should give me something like 96... see if that makes any difference... car needs 95 so maybe not... but we'll see.
