> I am curious about my engine oil consumpyion. REBOUND is is hull # 347 with

> It runs great, I had the MAX-prop repitched with a max rpm of 3600 and I
> cruise at 2800 rpms. My mechanic isn't concerned about the oil usage, which
> has been consistant since I got the boat 4 years ago, 400 hours ago. I am
> going through a little more than 1 ounce per cruising (motoring) hour. This
> seems a little excessive to me, more than anything its just a pain topping
> of every day or two when we are cruising. Most of the time it's not a big
> issue when I'm motoring out into the bay and back for a race.
> 
> I use Delo SAE 100 - 30.

> Does this consumption rate sound normal. I'm not too worried yet but when
> my oil consumption exceeds my beer consumption, I'll be forced into action.
