it should help with the problem but i dont know if the oil level being higher will totally eliminate it...due to leaking i had to switch from mobil1 5-30 back to valvoline maxlife 5-30 with my last change...oil stays in the engine much better (i haven't seen any leaking the last few weeks or so) and i starting to think it helps with the startup rattle

we moved a month ago or so and now i have to park on the street..sometimes facing uphill and sometimes facing downhill...i haven't noticed the cold start rattle in some time
