Reply to Bob's Post: Here is my immediate problem - My wife is in the suburban about 15 miles from home. I went out in the garage and there is about 1/2 quart of oil on the floor. (She had the oil changed at a "quick-Lube" yesterday, so I figure it is leaking from the oil plug or the filter). Anyway, I need to tell her if it is safe to drive home or park it. What do you think?
You need to have her check the oil before she even starts the motor again, if it is low have her ad some. You can be down to a half quart and still have pressure but that isn't good enough. As long as it has oil in it close to the full mark she will be ok. But, even if you have to drive over and do it your self, it beats having to buy a motor.
