One of several things must be wrong with my engine. I'm hoping you can tell me some of the possibilities. Here is what is happeneing: I add oil to my engine, and the dipstick reads the same amount as before I added it. I added three quarts to the engine, and still, it says add..exactly where it was when I checked it first. Where is it going? Its not leaking, because I would see it in the driveway.WTF?
