Didn't someone do a test on this site that concludes that the engine HAS to use fuel in neutral to keep the engine from stalling because the drive line is no longer spinning the engine, so in neutral the engine uses fuel to keep it running? If I'm not mistaken, but I remember someone doing a scangauge test and coasting in neutral uses so much fuel per hour and coasting in gear doesn't. Correct me if I'm wrong though.
