anyone out there have an Generac XL 4000 generator running there trailer at the dunes? just got one, couple q's
 

guys i just picked up a used Generac XL 4000 generator to run my TT, my question is how to change the oil... i know the newer models have a spinable oil filter.. but mine must be an older style.. it does not have one anywhere.. the generator itself looks the same as the newer ones.. anybody know?
thanks
JJ
