RE: Air/fuel ratio monitors

Ron,

<< Do any/all of these work with leaded gas?>>

This from the K&N site
http://store.knfilters.com/airfuelmonitors.htm

The oxygen sensor in your K&N Air/Fuel Monitor assembly is not compatible
with leaded fuels or any fuel additive containing lead. Leaded fuel will
contaminate the oxygen sensor causing it to deliver a false reading. The
Monitor can, however, be used to momentarily test an engine burning leaded
fuel.
