$4/gallon for regular will probably mean $4.50 for hi-test and $5.50 for
avgas. Not a lot of difference, but still not $7

I use car gas in my plane. I filled it two weeks ago for $2.89 per
gallon. I flew to LaCrosse, WI that same day and paid $5 per gallon
for avgas.

I don't think $7/gallon avgas will be much of a stretch.

Well we're already paying $1.64(NZ) a litre for super (road) so we
must be well over the $7 per gallon avgas
