I'm using this hypothetical to illustrate the point that: tradeoffs exist, and that you (we) may not have full insight into the full complexity of the trade space that the engineers were working with.
Putting some random number of hypothetical mpg improvement was clearly a mistake, but I assumed people here would be able to get the point I was trying to make, instead of getting riled up about the relationship (or lack thereof) of oil filters and fuel efficiency.
