Welcome. Sounds like you got good info and advice from the PO. As for 
oil, I'd expect you'd not have any problems reverting to synth. The 
only potential difficulties are said to be at times when high-mileage 
engines are "converted" to synth after a lifetime on regular oil. The 
quantity (4.5 q) is about right, but I go by dipstick rather than a 
set volume; however it certainly is more than 4 quarts--with filter 
change--but less than 5. Take care to _not_ overfill. Avoid cheap, 
crappy filters like Fram, etc. The recommended Mann or Maele (German) 
filters cost little and  are worth the effort to find (e.g., The 
Parts Connection sells Mann filters for $2-$3/ea. 

Since you were lucky enough to get a full history you should know (or 
find out) when the last timing belt replacement was done--don't 
forget that the recommended and *prudent* interval is every 60K 
miles. The 3B is an "interference" engine, and the momentary meeting 
of valves and pistons after a timing belt failure will set you back 
far, far more $$$$$$ in repairs than the cost of a timing belt 

What's the mileage??? What color??? Where are you located??? I 
certainly hope it wasn't listening when you called it "infamous"! :-)
