You can use anything that’s made for racing or motorcycle chain.
I clean my rear gear and chain between track sessions then spray on some thin liquidy chain oil then use some thick Burris chain oil on the inside rollers of the chain then spin for the spider web effect.
I’ve also used sticky Maxima chain wax by itself between sessions. The trick to cleaning it off is to spray a little bit of carb or brake cleaner and it wipes right off. Don’t hose your chain with cleaner or you’ll wash the lube right out of the rollers.
