Default Another oil change completed......

Just did another oil change on the '94 w/65,000 miles. Used Mobil 1 10W-40 High Mileage even though I am not at the 75,000 threshold. Upon start-up oil pressure is right there within a few seconds. When first started cold pressure is close to 80 lbs., when warmed up, pressure is around 35-40 lbs.(I am assuming 2nd large middle mark on the gauge), @ idle.
Also have noticed, although not overly warm outside temps, the chain rattle seems to have been eliminated with the 10W-40 compared to the 5W-30. As has been mentioned before that the thicker oil may help this, it appears that is does work. Having restarted instantly after shut-down, or letting it sit for awhile, so far no chain rattle. Now, just last week on a trip with the old oil still in there, I was getting chain rattle, so this is a good thing. I may not have to be concerned with doing the chain rattle fix after all.
