The '97' octane fuel they sold back then is pretty much the same octane as what they sell now as 93 octane premium. (Minus the lead of course). Back then they tested the gas at the refinery and advertised that number. But the octane declines as the gas ages, and by the time you put it in your car it is lower. Eventually they changed the standard on the displayed advertising to be the average of the refinery test and the pump test.

Timing won;'t have much of an effect on fuel consumption, basically (given a sound engine) advance it in small increments until you detect the faintest pinging, then retard it a touch from there.

Inspect the plugs to see if they look sooty. When the D-Jet FI gets out of whack it often runs rich. This allows the car to run pretty normally, but shoots the fuel consumption quite high.
