Subject: [Saab_c900] When was APC introduced in the Saab 900's?

Hi everyone, Here in Sydney (Australia) the local service station has, as of this week, stopped selling lead-replacment petrol (aka LRP) and it's being phased out by most oil companies in Australia over the next 12 months. BP, who supplies the service station I prefer to use, is now selling it's newly-concocted 98 octane 'BP Ultimate' unleaded fuel out of the former LRP pump. Since it's 'unleaded' it looks like I will need to start using unleaded fuel additives in my two Saab 900's with B201 engines (1983 and 1985 builds). I know a few people who run older cars (not Saab's) on ULP and use additives for valve protection. I know that the 1980's where pretty much the transition period, at least here in Australia, when cars changed from running on leaded fuels to 'unleaded' fuels. When exactly did Saab start supplying 900's with APC, and how do I tell if my two 900's have it? My 1985 900 has the later version of the B201 block with the starter motor under the intake manifold instead of under the exhaust manifold (my 1983 900 has the older style). If my 1983 900 has APC, it should run on higher-octane unleaded fuel without a problem. LRP is 95 octane here in Australia, and standard unleaded is around 93. Most of the newer high-tech fuel mixtures are 97 or higher. What do others think? If the cars do have APC, are there any other things which can be affected apart from the valves by running B201 engines on unleaded fuels?
