So, what's the final consensus on oil-changes?
For years, I've followed the "3 months or 3000 miles" rule.
Now, my GM owners manual says; "Wait 'til the "Change Oil" light comes on".
At 5000 miles, I got nervous, and changed the oil, but it still looked clean and clear.
????
( I wonder if GM is the only maker with a Change Oil light )
