for a old engine like your crx i wouldn,t use an oil too light as the engine would be old and worn say a 10w-40 or even 20w-50 and i wouldn, be using full synthetic oil in it either
Depends on the car. If it was a worked B or K series, then yes, use expensive fluids. For an engine with stock compression, cam timing and such, even a cheap synthetic like Castrol Edge is more than enough for track.
Thanks very much for all the insight guys. I ended up with Pennzoil semi sync 10w-50. Seems nice and smooth and quiet and i put in a good purolator oil filter too. Ill be getting it all changed in a couple of weeks when i get it serviced anyway! Thanks everyone for your help
