Yesterday I posted smog test for our '91 Carat...I just dug up
        the numbers for the last smog test for my '93 Mercury Villager
        and noticed that the MAX allowable numbers HC were lower. I've
        included the Villager's results as the second set of numbers
        among the Carat's numbers below.

         2500 rpm
                    MAX allowable      Average     Measured    Result
         HC ppm       0180/170       0020/0013    0024/0010   PASS/PASS
         CO %          1.00            00.10      0.00/0.00   PASS/PASS
         CO2                                      14.6/15.0
         O2                                        0.2/0.0
         RPM                                      2527/2471

        IDLE RPM
                    MAX allowable      Average     Measured    Result
         HC ppm       0120/0100       0030/0017   0023/0022   PASS/PASS
         CO %           1.00         00.10/00.00  0.03/0.01   PASS/PASS
         CO2                                      14.3/15.0
         O2                                        0.6/0.0
         RPM                                      0890/0758

        The Villager had 112K with plugs that hadn't been changed since 64K
        when the smog test was performed. BOTH vehicles use Mobil1 and
        are fed a diet of Chevron regular(87octane) with Techron(tm).

        Offhand, I'd say that the engine management/emission controls
        on the Villager do a somewhat better job than the Carat's.
