K3rolla

hey everyone. ive recently bought a KE30 running a 4K head, 5K block and a SC14 supercharger. ive only just noticed that my charger is lacking in oil :oops: . i was wondering if anybody would be able to tell me (apart from genuine toyota oil) which oil i can run in my supercharger and approx how much it will cost for it? this is my first charger and id like it to last as long as i can make it. havent exactly had it off to a good start so far. Last owner was running the carby at a crap idle, left mounting bolts out of the charger, lines left unplugged etc etc. Any help is appreciated. cheers
