Thanks Iva. Can you elaborate on the fuel thing?

Seems like many don't like the NB seats. Are there reasonable aftermarket
solutions, rather than adapting old NA seats?

My '90 was perfectly happy with the lowest octane gas. Ran like a
trooper no matter what the conditions or acceleration. The '04
prefers the mid-range octane rating. Under hard acceleration,
particularly uphill, I'll get some pinging with the lower octane
gas. If I'm doing any type of track event, or extended
"spirited" driving, I'll fill her up with the higher octane gas.
And that translates into more MSUs (Miata Spending Units) for gas
and fewer for fun.

Of course the ethanol content doesn't help any either.

Ok... I wonder if that's an NA/NB thing or a 1.6/1.8 thing?

My understanding has always been that alcohol burns more slowly than gas,
which gives a higher-octane effect - pinging shouldn't be alcohol-caused
(unless you're drinking it!

Maybe a little of both?

I guess I wasn't clear - I meant that the ethanol content has
lowered mpg noticeably. I'm not blaming it for the pinging.

Oh, got it... yeah, definitely. I imagine it lowers mpg about, oh... about
exactly how much it stretches the gas out. Good thing we have politicians to
plan this stuff for us.

That was true for me: I lost 3 mpg when they shifted to E10. Power is
down by a similar amount. Ethanol is corporate welfare for ADM, plain
and simple. It results in a net INCREASE in greenhouse gas emissions, if
we include the diesel tractors, ag chemicals, and transport in diesel
trucks. The higher the ethanol content of a fuel, the greater the
negative consequences.

At best, it's filler for gasoline...sold at full gasoline prices.
