Pretty much will run on anything you wanna put in from 5/30 to 20/50.
In my past 3 yotas I've ran castrol gtx high mileage 10/30. My current one I'm running Moblie one 20/50 trying it out but going to switch back... I'v been running napa's gold oil filters which help cut down on the start up rattle of the chain.
What do you all run for filters?
