I recently bought a 1978 Honda CB250T that is in good shape. I think I should change the oil and have looked for "conventional" or non-synthetic oil and have not found what I think I need. Something with JASO-MA(2), but not sure if mineral oil or "half-synthetic" would be OK for my bike. I live in Lugano but would order it if there is no place to buy it in-store. Maybe Tom can help, he is the expert in these areas.

P.S. I use it in the gearbox of our '81 RS125 2-smoke.
Thanks for the info, Tom. Unfortunately, the shop in Mendrisio is closed up, a victim of Covid maybe. Ordering it will be easy, though.
