So what happens when 100LL is gone anyway?

Why is that?

hm, maybe a uneducated guess: most (not all) Americans are not really into
innovation, and most are not into anything being not "made in America".

We purchase a high percentage of imported cars. Even our domestic cars
have so many imported parts they now say, "assembled in America":-)).

Most Americans don't have the need to travel outside of their country, so
their point of view is most likely very America-centered (this also backed
up with little to no information on what is going on on the other 70% of
the world)

The above it true from a social standpoint.

. So everything coming from abroad is seen as bad.

30 years ago I'd have said yes, but now most of the imports are
considered moving up to quality compared to US automobiles..

However, the car's name be it Honda, Toyota, or what ever does not
indicate where it's made/assembled. It pretty much depends on the
model. One might be assembled in Middle America and the other
overseas.

As to Diesel engines and fuel here in the states, the fuel, quite
often has high sulphur content and the engines put out a lot of
particulates. Between the two, this in general this has given diesel
engines a bad name for being environmentally unfriendly even though
examples exist that run clean.

Many things keep the precision engines with good economy from being
imported. Some run high compression and those develop nitrides from
the high combustion temperatures. Quite likely some just don't figure
it's worth the effort to go through the testing to be sold in the US.

You will find that many of our engines run rich to keep the combustion
temperature low and then have to pump air into the catalytic converter
so the excess can be burned.

At least a good portion of the reason for poorer mileage over here is
due to some specific anti-pollution measure.

I am sitting here in front of my imported computer, sitting on my
imported chair, drinking my imported coffee, and not believing what I
am reading!

I don't know for sure, but I suspect that every stitch of clothing I
am wearing was imported too. When I drive to the end of the road to
fetch the newspaper (that is probably largely an American product) I
will be using an automobile that, while built in Maryland, bears a
foreign mark.

Hey! My Computer is 100% American... well as much as GM, Ford, or
Chrysler.

The motherboard came from china, the drives from Taiwan, Singapore,
and Japan. HOWEVER the Silicon in most of the chips came from
Michigan. The RAW Silicon was made here. The poly crystal was
shipped to Taiwan where it was made into single crystal and then cut
into wafers. The chips? Mostly Japan and Taiwan although more and
more are coming from China. My Router (D-Link) was made in China,
along my Link-Sys stuff. I didn't find any networking components,
regardless of brand that weren't made in China.

BUT it was 100% assembled here. Right here in my den with no
outsourcing. Albeit the software comes from all over the world and the
US companies are importing programmers from India. Still it (there
are 4 of them) was assembled, configured, and put into operation here
in the US.

I don't think there is a TV set made in the US any more.

I don't drink coffee!

Probably by child labor in sweat shops.

But in a plastic Chinese mail box?
I actually have a steel, US manufactured mail box from US steel.
Of course it's flanked by one for the paper and one for the shopping
guide that are of Chinese plastic.

Even if you purchased an American brand car you will find many parts
in it came from other countries.

I hope not :-)) That would be a sure way to burn out your catalyst.

Gasoline engines do run rich however at high load conditions, which are
not met during emission cycles. But the excess fuel turns into CO
instead of CO2 (thus burning more fuel with less O2) or even goes down
the exhaust pipe unburnt. Noone cares, at it will never be measured.
This is one of several reasons, why the ongoing tightening of emission
standards has become a joke by now.

The only conditions, when so called scondary air is pumped into the
(rich) exhaust is at fairly light loads during warmup. This is done to
get the catalyst to its operating temperature range more qickly.

At least a good portion of the reason for poorer mileage over here is
due to some specific anti-pollution measure.

There is a slight influence, but it's not a big deal.
