Question for you guys, when you guys switch oils do you drain the entire system or do you just run the oil low and add your synthetic oil on top of that. Is synthetic oil compatible with non-synthetic? Just curious. Thanks.
I plan on switching my sled over to Amsoil this year. What is the easist and best way to change from cat oil to sythetic oil. Do I need to drain the entire system and oil pump or can I suck the cat oil out add the new synthetic?
