Engine Mechanical problem
1997 Geo Tracker 6 cyl Front Wheel Drive Automatic 100, 00 miles

my 97 tracker has a knocking in the engine, I have heard it before on another car I had, it threw a rod. My ligh came on for oil and I didnt have the money for it until almost a week later, just before I put oil in, it started knocking, I just put 4 quarts oil in and I of stp oil treatment, it is still knocking, is there any way to keep it working until the first of the year because I cant afford an engine until then. Is there something else I can put in to keep it quiet and last a little longer? Please help. Thanks
