[Spits] Some 1500 questions

[Joe Curry]

If you used mid-grade or Regular unleaded and did not get any pinging, then
you are throwing your money away using the Premium grade.  The difference in
the fuels is the octane rating and the only thing that octane does is
increase the temperature at which the fuel ignites.  If your engine does not
show signs of pre-ignition using regular fuel, then you are not gaining
anything by using higher octane fuels.

I've got a 76, I assume it's 9:1.  I use premium fuel.

The cost difference around here is about 12%.  That means, at 25 MPG, 
it costs an extra $12 to go a thousand miles.  If I couldn't afford 
that, I couldn't afford a Spitfire.  I have used regular and 
mid-grade, but not in the hottest part of the year.  I didn't notice 
any problems, though.

Of course, in sunny San Diego, it'll be a little more expensive.  But 
it's been my experience that higher octane fuel is available most 
everywhere.  You could store a bottle of octane boost in the boot for 
emergencies.
