Oil gauge is fluctuating...on Low when at a standstill...moves up when i hit the accelerator...i just added 3 qts of oil...and i also have a coolent leak????

That is a good sign, it is working, my oil pressure fluctuates like a tachometer, at idle it is low, like 20 lbs, then when I 'm cruising, 35lbs, but it goes up and down when you pump the gas. The pressure gauge is reading the oil pressure at the top of the engine, it will show 45 lbs with only 1 qt of oil in there, it is not an oil level gauge. You might have an oil light buried on the dash somewhere that will light up if the oil gets too low. ,, Now about that coolant leak, it should have nothing to do with the oil pressure. Is it a hose? Radiator? Joint at the top of the engine? Where is it leaking, and what is it doing? Does it over heat? Or did it overheat? Is there oil floating at the top of the radiator? Does it blow steam out the exhaust? Does it have coolant or just water? Check it out. hope this helps.
