Just to buck the trend, I have an 06 rev-up model and it uses oil at at the rate of around 0.5 ltr per 1k miles. It has done this from new and has not got any better or worse over the 22k I have now done. The dealer states that it is within manufacturer's tolerances of up to 1 ltr per 1k miles. As has already been said though, it's this particular model that appears to be effected and it doesn't really present any problems so long as you check the oil on a weekly basis which any self-respecting owner of a high performance car should do anyway.
