Valvoline Maxlife 5w-30, and it was only a 2,500 mile OCI too. only reason i got it out so quickly was because i was quite eager to get the ARX in. anyhow, my magnetic drain plug had like a little pile of iron bits on the end of it (WAY more than usual, sometimes there isn't anything on it at all). anyone else had this problem with maxlife? car has 145,000 miles on it.
