but i guess the general consensus is that at 80 ish expect a drop of aroudn 5mpg atleast!
Personally I see no reason why you should be exceeding the speed limit in the first place, all you've doing is putting yourself and other road users at risk, and costing yourself more money, and for what a couple of minutes saved? for example if I drive at 70mph it will take me about 40minutes to get to work, if I drive on the motorway @ 80mph I'll save 2.5 minutes, I'd rather keep my licence and get a few £ in my pocket.
ordered a new maf anyway from vw see if it makes it any better
other than the affect the rims have had on your MPG why do you think you need a new MAF?
ridg: whats teh benefit of the green cotton filter as a pposed to normal vdub filter i take it this is air filter .... any ideas where from and price? or is it the same as the oem vw dub filter?
an after market panel filter, will allow a greater air flow, than the standard one, which means that it's easier to satisfy the demands of the MAF, whilst the VW is more than good enough, an after market one lasts longer (assuming you clean it properly when you're meant to) can give a better throttle response and improve the MPG whilst cruising.
