[Fot] gasoline comparison

[Tim Murphy]

As I recall from another article, the ethanol is mixed at the distributors, more or less at the end of the pipeline.  I think it had something to do with the ethanol not being good in the pipeline.  Plus, I think most of the ethanol plants are near the corn (upper midwest and great plains states) and it wouldn't seem to make sense to ship it to the refiners and then back north and east.  It has been a pretty large expense for the distributors to store and mix the ethanol as I understand.

  And there's an ethanol shortage, that won't go away for a long time.

    As of September 1, 2008 all gasoline must have 10% ethanol by Federal 
    mandate.  So I was told by a Mobil distributor.  As always, a really well 
    thought out Federal mandate.  At the same time they raise the CAFE standards 
    they lower the MPG by mandating ethanol.  There was also a bill in Congress 
    to increase the mandated percentage of ethanol.  Guess which lobbying group 
    was pushing that bill?

      When MBTE was first proposed as an additive the local Triumph club 

      president

      did a bit of investigation.. according to what he'd come up with the MBTE

      mix was designed for catalyst equipped cars... for non-catalyst equipped

      cars (the bulk of the Triumphs) the incompletely burned emissions were

      actually worse for the environment.



      Just another example of poorly researched "science" being foisted on the

      American public.  Don't get me started on the R-12 vs R-134 bs.

        Helps the emissions (as the MTBE was supposed to do also!).



      Don't kid yourself.  For anything made in the last 20 years or so, it does

      absolutely nothing for emissions, as the computer just tweaks the mixture

      richer to compensate for the "oxygenated" fuel.



      For most cars made before 1970 or so, it does make them run leaner, which

      does reduce tailpipe emissions.



      But that leaves an awful lot of cars in between with fixed mixtures that

      were already tuned lean running on pure gasoline.  And it only takes one 

      of

      them pushed into lean misfire under cruise conditions, to emit more

      pollution than the oxygenate could reduce in hundreds of pre-computer 

      cars.

      Of course eventually they'll burn up the valves and so on, but you'd be

      surprised at the number of them still running around here.  And remember,

      these are the only cars where oxygenated fuel is supposed to reduce

      emissions at all.



      And of course for Triumphs, we just adjust the mixture to suit the fuel, 

      so

      it does no good at all.
