Why can't the 3rd generation Mazda rx7 safely coast downhill in neutral?

처리 내용

You know, I can understand why they would say this but I'm not sure I could fully describe it in words haha. I think it has to do with how oil is circulated through the rotary motor. If you're going downhill the oil pick up may not be doing enough to circulate the oil through the engine when you're not in gear. I suppose that if you kept it in gear, the oil pick up would be operating at high rev's since you're cruising downhill anyway. I'm not really sure how this would affect exhaust temps...perhaps oil starvation is the reason why it does increase the temps?
