Smelly Talking about the air freshners, I have noticed when I first open the door of my copen it smells like the yellow fields(rapeseed). Is this normal or just my unusual observation ? Can I also ask while I am here, what rpm do yous normally drive at and at what gear when doing 30mph(48kph)? I normally go up to 4000 rpm in 1st and 2nd gear and then stay around 3000 in 3rd gear. I drive in 4th gear when doing 30mph and the rpm rests between 2 and 3. Is it the most efficient way ? Mines a 659cc engine.
