That sounds like a really worn out engine, I am surprised it even starts and runs with that kind of oil consumption. Time for an engine replacement or overhaul yours if it's not too far gone.

Burning 5 quarts of oil in one day?! Contact the manufacturer of the spark plugs with that info. They may purchase you a new engine just to get the plugs back to see how they lasted past one day.

If the rear seal is leaking 5 quarts of oil a day and you're burning oil too with the blue/gray smoke then that motor is shot and you either need a complete rebuild on that motor or a replacement motor from a junkyard. Don't drive that car anymore as you are polluting the air we breath and probably blowing oil all over the vehicles behind you on the road. Get a new motor or a new car. Kenny/MrblueOval
