I have been using Rotella 5-40 T6 for the engine.....amsoil chain case lube for tranny....amsoil severe use 75-90W gear oil for front differental..and the Polaris demand plus for the hubs....take no chance on the hubs...never a problem....great cold starts an shifting....and front AWD kicks in no problem.....
Synthetic chaincase lube for the transmission in my ATV. Just like my sled.
2 stroke oils... Any TCW-3 NMMA rated oil should be fine. Some make more crud than others. It prolly came with the old Polaris "Blue" oil like my Indy. I'm running Pennzoil marine 100% synthetic outboard oil and it's reasonably clean burning. I bought six one gallon bottles from China Mart a while ago. Not sure what they carry now.
