yeah, use 10w30 to lubricate it. go to kilby's site and download the york manual. it tells you how much to put in and how to measure the oil. does it make any noise? i had a bad york and it was screaming when i started it up... something inside wasnt right. so i got another.
for the price of a used york, it wouldnt hurt to get another.
