I usually hand tighten then tighten a little more with a tool. Well I just got one of those new mobil 1 filters that is made in South Korea. my tool didn't fit and I only hand tightened it. does anyone else only hand tighten? do you think ill have a leak or will it be okay. I took it for a drive and it didn't leak but hoping it will stay that way. thank you for your answers in advance
