Hi everybody, new to this forum, great info and resource! So would anyone see any problems with using Mobil 1 0w30 in a '00 BMW X5 if I change the oil every 5k or so? I know it's HTHS number isn't that high but I'm not trying to go 10-15k and my wife drives it...easy hwy miles. For some reason I can't easily find any LL-01 around here (Seattle) and I don't really need the long life since I change oil more frequently. Also I have quite a bit of valvetrain or other noise upon cold startup, is the "0W" going to help with that since according to BITOG: "all oil is too thick when cold"? I was running Elf Solaris 5w30 but it's also a hassle to get, I used some Quaker State Synthetic (cheap wal-mart) and it allows this noise. Thanks
