I think 1 quart to 1.5 every change is a bit of an exagguration, if I may say so. Even with VTEC, it's not even close to that much of a problem. What you're talking about is. It's either burning it or it's leaking, can't be neither, because the oil isn't some kind of phantom fluid. What kind of oil are you using (I'm sure that's been covered already, but might as well ask) But yes, definitely pester the service dept, it's only 4 years old and that's pretty peculiar for a car. Hell, my old '87 Prelude burned less than 1/2 a quart between changes, and that was at 140k miles. Speaking of which, how many miles do you have on it? Just keep reminding the service people that it isn't normal, and it's a NEWER car, and if they can't help you, you'd like to either speak with the DSM (district service manager) yourself, or have the service manager call the DSM while you wait. If you are able to speak with the DSM, just be polite and let him or her know the story and that it's HIGHLY UNUSUAL (emphasis there, just keep using it) and I'm sure you'll get some help, and hopefully a leg up.
