my oil sensor has been broke now for a while and because of that it does not tell me on the dash how much oil i have,, my question is when i check my oil cold in the morning it is full on the dipstick,, when i drive when it is warmed up there is nothing on the dipstick and that is almost 2 quarts,, i check it every time i fill up and it is always the same, cold full warm empty. is everyones like that
