what ratio should i be running?

i have a 1982 rm125 and have been running it at 22:1 like the manual says but times are changing in the oil world since then and have heard that most 125's run at around 32:1 what do you guys think? im tired of running out of oil because of the oil ratio? any ideas at what ratio i should run my rm125 at?

btw- i am using the good oil, not cheap stuff!!
