Ok sO I changed from my regular Pennzoil high mileage oil to castrol synthetic blend but when I went to refill
I put 4 quarts like usual and didn't even touch the dip stick so I decided to fill the whole 5 quarts and guess what it filled below the top why is that ????

That's impossible. Either you're leaking it back out somewhere as it's pouring in, you're reading the stick wrong, or you're pulling the wrong stick. Did you wait for the oil to all settle back into the pan after running the engine? Did you check it with the engine running?

Did you remember to put the drain plug back in?

Nor the car is leaking and I turned the car on to let the oil run to the filter its just weird
