[T3] Question about D jet idle issues 73 T3

Tue Jan 26 19:04:47 PST 2016

89 is marginal at sea level, but if thats the best you can get, im
surprised. you'd blow up any vintage muscle car in quick order at sea level
with 89, our premium here in NY is 93.

Around town 89 is probably fine, Tram knows oregon gas better than me of
course and its not only the octane, but the additives they use and that
changes from state to state.  89 Nonthenal is probably better than 89 E10
too as it will run richer.

Tram has me running Premium only in my '69 FI/AT square, which is 89 octane
in Oregon.
