	I don't know about hotter, but I know better.

	92 Octane-Yes. The kids in Wolfsburg spec. 91 Octane in the manual for
	my '91.

	I use Chevron Super. Ruby runs better and cleaner.

	Maybe, but even if it did cost more, as long as I'm not in hand-to-
	mouth mode, I prefer to burn the best fuel.

	I never had heat problems with my '71.

	Gawd! 10 & 13 MPG? What are you driving? An Econoline 3/4 ton? :-)

	Definitely. I remember cruising up I-205 east of PDX on the way home
	one night and realizing Ruby was lacking power. I freaked imagining
	a big-bux part replacement for some premature failure....and then 
	remembered to my relief that the last time I fueled, the depot was outa
	hot stuff and I opted for 87 grade.

	Not only is there a difference with my '91, I experienced a similar 
	differential with my past '71.
