I was doing a bit of research on fuel for the newest addition to the family, and I thought I'd share what I found in the way of which cars can use Unleaded Petrol. The findings were good!

Subaru

Regular Unleaded
1800 Sedan & S/Wagon 1980-1984 EA81
1800 L Series (carb) 1985 EA82
1800 Brumby 1985 EA81
Sherpa 700 1982-1985 EK42

Premium Unleaded
1800 Vortex Turbo FI 1985 EA82T

most japanese made engines are already designed to use unleaded fuel, from as early as the early 70's, as thats what they were using over there long before we did here in australia.

my mate's '72 celica runs on unleaded, no sweat. standard, original motor, has been doing so for the last 18 months with no ill detriment to the motor.
