hey there
when i first got my rc8t i ran 15f 17c 7r. since starting racing the thing i tried 10 10 7 then 10 10 5 and found that to be a good mix. that is running a mmm v3 and a castle 1800 kv motor on 5000mah 4s. appartently thicker oils for bashing and thinner for racing but it comes down to personal preference at the end of the day. if you can get hold of a range of different grades then try out various combos
