Hi, sorry if it's been asked before but can someone tell me the best oil to use for a gearbox oil change on a DT 125RE. Thanks.

My choice is always Rock oil Guardian.

As drty says " gardian is good, Sikolene MX gear oil, too , As long as its not Car engine oil, as it has anti-friction agents added, and will cause clutch slip ,

Anything for motorcycles. It hardly overstressed in there.

Never put anything fancy in the dt and thats had some right greif over the years.
