If it is a problem with the paint protection you could use a paint cleaner, which should clean it off, and then polish the car. But I suspect it could be a delaminating clear coat that's your problem and not the protection coat at all. I would suggest you take it to a body shop and have them cast their expert eye over it.
If your calculations are correct, your car isn't returning the fuel consumption it should. The Australian Design Rules (ADR) test fuel consumption on your car is 11.5 litres/100km city driving and 7.2 litres/100km highway driving. From those figures I'd reckon on getting 11-13 litres/100km in normal round-town driving conditions. I suggest you take it to a Holden dealer to have it checked again.
