Looking for some advice on what oil to put in the above machine. I have the service manual which says "only use a high quality detergent 10W/40 motor oil with an API classification of SF or SG".

I happen to have a 10L Castrol Magnatec semi-syn 10W-40 oil in the garage. Question is do I need motorcycle oil or will automotive oil do the job?

Ah - does look like a GY6. Plenty of cheap parts available from them too

Just about everything wears a Made in China sticker now. Smaller Stihl chainsaws are Chinese. Almost all the Apple computers/tablets/phones. Almost hard to find things made at home...

Could this be a Chinese 300cc machine? Sold under different brands including Buyang and Feishen. See manual at http://www.buyangvehicle.com/pdf/MANUAL- FA-D300 4WD.PDF

Parts are available (assuming this machine is a Chinese 300cc) through AliExpress etc from China - see https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20180824150511&SearchText=buyang+atv

Having exactly the same problem. Need the factory manual to work out what's going on, but need 10 posts...
