Crazy gas milage... help!!!
Hey guys I went from 13.4L/100k to 18.4L/100k overnight. No codes in the engine and it seems to be running ok, maybe a little sluggish. Any ideas on where to start.

I have the following- new fuel filter, new air filter, recent oil change.

newer O2 sensors (all 4)
new Mass air

new cam sensors (both)

it's a 3.0l 2001 X5 180k on her.

Thanks for and direction.

Andrew
