Hello all,

I had my MB 190E since it came out. I have been very religious in maintaining it. I do 3000 mile oil changes very religiously. In the last three or so months I have noticed the oil-level lamp comes on after about 1800 - 2000 miles after the oil change. At this point it takes up about quart to quart-and-half oil. I use Quaker State brand. Is this normal? I don't see any visible leaks but it might be internal. Any thoughts? Please pardon my ignorance about car engines.

Thanks
Asim
