[s-cars] Re: HCs and MPGs

[Serge Filanovsky]

Gentlemen,

A while ago I posted to the list about getting some high HC emissions and
less than 20 mpg on straight highway trips (cruising in the neighborhood of
our cars' vintage).

I want to thank all those who replied with meaningful info, and Paulie K. A
non-scientific summary goes something like this:

I am not alone, there are a number of you (3 or 4 replies MTM Stage I+ or
equivalent) who get less than 20mpg in highway cruise mode.  Several of you
are getting in the mid 20's. Hap being one, which boggles my mind.

With plenty of travel planned for the holidays, I would like to at least
once get 400 miles out of a tank of gas, will be changing various filters,
sensors, plugs, connectors, and will keep the list posted if any significant
findings occur.

Thanks again, all
