I have a 1959 Nash Metropolitan with an oil bath air filter. Would you recommend just leaving it alone or should I replace it with a modern air filter? (The replacement looks the same from the outside so I'm not worried about the appearance.)

Iwould say yes but only from the ecological point of view.Eliminating the solvents needed to clean the filter and the ease of replacement would be two strong points.

  • I'd say yes because you're likely to get better filtration with a modern filter. Even contemporary oiled air filters don't work as well as pleated paper filters (although they do flow more air).
