Any opinions?
(OP)
I am interested in whether anyone can "accurately" help me answer the following - hypotheses with calculations welcome!
How much of the following would an "average" car engine take-in/consume over a 10 year period:
1. sand/dirt;
2. acid;
3. any other corrosive/abrasive impurities likely to contribute to engine wear?

RE: Any opinions?
As for corrosives, just ask the experts at Toyota, when their typical world class engineers goofed on their engines crankcase ventilation system which ruined many engines due to condensation, Chrysler and their V-6 engines with too small drainback holes in heads, early 80's Ford 5.0 engines with poor crankcase ventilation and copious amounts of sludge.
Sorry if I offended any OEM manufacturers, I got this information from the NTSB Recall and Warranty website while doing a study recently.

4. How much crud is in the gasoline consumed -grit,tar, wax, asphalt?
5. How much crud in new lub oil - I have been told that new oil is cleaner AFTER it goes through
the engine oil filter.
6. Do oil "additives" increase wear - I have heard that half of multigrade oil is additives?
7. What is the creamy liquid in the bottom of the oil pan that does not drain out during oil changes?
8. Has HEPA filter technology been applied to engine air filters?
PS.
Given the gist of the original post - look at the other side of the coin -
Routinely, bus diesel engines with 500,000 miles on them that are opened up show no wear at all.

Make sense?

7 =water+oil emulsion.
This could be because your engine never gets really hot, or it could be that you have a cracked head or a head gasket problem.

RE: Any opinions?
Ya well - the idea was that if the NEW oil was actually CLEAN the filter would have no effect - the word used was "cleaner"
7 revisited
Isn't the idea of detergent in oil - to keep the water in suspension so that it can be drained properly during an oil change.
RE: Any opinions?
It also helps to emulsify oil, but this emulsion is the creamy substance you speak of.

The oil was probably 10W30. Other "facts" not recallable.
