I have 3gen GS300 AWD, same problem. High oil consumption. back about a year ago the light came on and off again I didn't thought of it too much. Got an oil change about 3,000km the light came on and it is actually nearly empty. Got it topped off and about 3 weeks again light came on and nearly empty. I've put the Lucas oil stablizer with the oil change and I check it every week and it goes down by about 1/4. I just checked it on cold engin it's at half.....*sigh* anyone know what might or what is causing this problem? and any ideas what/how to fix???
thanks
