I wouldnt trust that Ph#%r##n little Amber light!!!! :

It used to come on at around 190k ish and since I put the K&N in (No air box mod) I can get to 206 and the light still hasnt come on (commute). :

But when I fill her up the quantity has varied by up to 1 to 2 litres. Sooooo I dunno 'bout putting a mileage on the k's left when the light comes on. You'd want that "Thumb" suitably greased , serviced and in good working order. ;D [laugh]
