Well I drained all the Mobil 1 0W-40 today from my first oil change. This oil had 4000 miles on it. I also dropped the sump to check for any metal and debris. This is a 98 with 84,800 miles on the clock. I did not find any metal in sump, only the 11 dark brown plastic chips. I believe this is from the chain tensioner ramps, correct? The oil pump pickup screen is also clean. I will be using Castrol Edge 10W-40 per the advice of the forum. Any thoughts or recommendations guys? Really appreciate all the great responses from this forum.
