My car seems to be doing the same thing. I can't figure it out.
I'm losing coolant, I know, I can see it dripping from a hose [see my other post]
The coolant loss seems to be less severe than it was before, I think my shop might have fixed it for me if it was an easy fix. But the oil seems to be just disappearing.
I know it'* not burning oil or coolant, I checked the exhaust. My guess is it'* leaking out of the bottom somehow. I can see oil all over the bottom, but I assumed that was from when the oil cap blew off and oil went everywhere [last year'* disaster]
Do you seem to have abnormally low oil pressure? I do, and I think it might be because i'm losing oil. But to me it'* not a big deal, I just keep an eye on the pressure, check it every so often, and make sure I keep a few quarts in the trunk. The way I see it, if it'* just leaking oil, it'* cheaper to add it every few weeks than fix the problem.
By the way, what color is the coolant supposed to be? After it'* been used for a while..
