I hope I remember this correctly (flame me if I am wrong): When you change to an oil with better cleaning properties, you can experience a higher oil consumption for some time. After that the oil consumption will go back to normal or better. This is because your piston rings is stuck due to deposits (correct English?). When these deposits is removed partially, you will get leaks. When all deposits have gone, the piston rings can move freely, and the leaks will disappear. -- Allan Olesen, Denmark 83 100cd man. 243k miles (just runs and runs and...) 87 100cd aut. 144k miles (wish it did too) 84 Toyota Corolla (no comments, hiding face behind newspaper) 66 Jaguar S (rusting/awaiting restoration) 65 Jaguar S (rusting/awaiting restoration)
