AFAIK most 99 and all 900 can run on unleaded fuel as they have alloy heads and hardened valve seats. This has little or nothing to do with octane ratings. I thought only H engines had APC, but if you have a solenoid valve on the top edge of the radiator, with vacuum hoses going to the waste gate, the pressure side of the turbo and the air intake before the turbo, then you have APC - and of course when there's a guage in the instrument cluster, saying APC...... -------- MH '72 97 '77 96 '78 95 '79 96 '87 900T8
