I agree with Stan on this one.  The internals have looked better on the engines I have taken apart as well.

  I would like to add that if you are adding MMO to your oil just before  a change, I would not recommend reving the engine past idle.  GUNK  makes a product specifically for this purpose, pre change cleaning and  the directions state very clearly to add the product when the engine is  cold and allow to idle for 5 minutes maxium and than drain and proceed  with oil filter change and adding of new oil.

  It is my opinion that driving a van with too much oil and or thinning  the oil substantially and driving at highway speeds for hundreds of  miles will do more harm than good.

  my 2 pennies.

half quart in your crankcase and the  other 16 oz in your gas tank and drive
the car about 300 miles or less. This will clean your piston tops,
undersides, ring lands, valves, combustion chambers, fuel injectors,
crankcase etc.
Then change your engine oil and don't bother with the MMO until you get
ready for another oil change, then repeat the above process before you
change it.
I've found that engines treated in this way never develop that coffee
colored stain in the crankcase interior and the fine particles of iron,
aluminum, bronze wash out of your engine case and leave no residue.
You'll never know how much cleaning it does until you pull down an engine
that has had the MMO routine run on it for five or six oil change cycles.
