Years ago, I read about someone who was in an area while a volcano was erupting. He said that there was a lot of ash in the air and the only vehicles running after a while were those that had oil bath air cleaners. The others all ground their engines up so bad they wouldn't run.
If I have recalled this account correctly, it indicates that damaging particles can make it through a paper filter system.
Shouldn't we reach for a goal of having every engine with the same compression readings as new and running as good as new at 250,000 miles? If only a few more dollars for better filters would move us toward that goal, why not?
