It would seem to me that you'd need to clean out more than the pan. There'd be build up on and under the bearings (if they're inserts) as well as the rings. Removing this build up would make for larger clearances.

I was always taught that you should NEVER go from non-detergent oil to detergent oil because the detergent oil would clean out the engine causing the above mentioned problems. This would cause the engine to burn oil or knock.

I tried it once and it wasn't long before I had a bearing knock. Granted, it could be argued that the engine may have knocked about that time anyhow.

The oil I get from NAPA is Vavoline. That's a name brand. The specs are printed on the bottle. SAE 30. Meets or exceeds service SB.

Edited to add that I have never had any problem using a good grade non-detergent oil. As with any oil, I change it regularly.
