Old Oil & Old Fuel Filter effect on MPG

I know that having a dirty air filter will drop MPG, what about a old fuel filter & old engine oil?

I don't know about the oil, but an restrictive air filter can hurt your MPG's.

I don't think old oil or oil filter will impede fuel mileage, nor would an old fuel filter unless its sufficiently clogged to cause the engine to run poorly. The thread title also mentioned fuel filter.

YMMV, but I've never noticed a fuel mileage improvement after an oil change or fuel filter change.
