2023 beta evo engine oil

Hello ,what engine/gearbox oil are most people using

I have a 2023 beta evo , manual says 10w 30

You are going to get a lot of different answers but the best oil to use in a 2-stroke motorcycle transmission is the oil that you can change more often.   10w30 is multi-grade oil which is 4-stroke engine oil, your engine is 2-stroke and the oil never sees engine cylinder operating temperatures, it does have a wet clutch and gears and for that I use the same thing I use in a farm tractor construction excavator which is also full of gears and wet clutch plates, UDT hydraulic oil ISO46.  Others will have other recommendations but this is what works for me and it is cheap enough to replace frequently and that does more to save your transmission parts then expensive oil left in there for a long time.  Only two things can pollute your transmission oil; water and dirt from internal parts wear.

With the beta oil choice is partly about clutch feel and avoiding clutch drag. I prefer putoline nano trans, motul 300v 5/30 is also really good - I've just done an oil change with this today as I've ran out of n trans. Many prefer ATF but I find the clutch isn't progressive enough with it. I've tried a couple of brands of light gear oil (the usual gearbox oil for 2 strokes) and they caused a little clutch drag.

Oil change costs me about 7 bucks 🤓 (roughly the same cost as one litre of race fuel) and UDT works good even in sub-zero weather ⛄ like we are about to get here very soon.  If the clutch drags because of the hydraulics just raise the idle a little, that works.  

If your clutch makes noise and the oil drain looks cloudy that's water, water happens a lot when you do deep water crossings or the engine insides are exposed to condensation, such as riding in winter 😎 or power wash your bike.

I started riding Beta in 1990. And still to this day Atf works the best. You can get it anywhere and its cheap. So change it often. 

TOTTY79 is correct that motul and other brands are more progressive, but that is not what you need in a trials clutch.
