I have a 1.8 SXi W Reg (x18 engine).
Its been happening for a while now, but would like to get to the bottom of it.
I top up to max and after 200-300 miles it will be down to half way, this cant be normal?
No blue smoke, no visible signs of leakage on the sump/driveway and no contamination in the water.
I'm sure it just cant dissipear, can it? I know my oil is over due a change, and plan on doing this on the weekend, but can old oil just vanish?
