I knew my motor burned a little bit of oil, so I went and checked it today. It was two quarts low and I just did an oil change on it about 300 miles ago. It's not leaking out anywhere, so a quart every 150 miles seems pretty catastrophic. A rebuild is certainly not in the budget right now, so I'll be spending a few more dollars on a quart of oil every gas fill up.
Yep, that's a pretty aggressive "burn rate." It's funny how years ago (dating myself) it was common to see cars going down the highway billowing blue smoke. Pretty rare sight these days. Good luck and keep plenty of oil in that pretty blue baby.
