    I would vote the ATF type F in primary I like the colour which makes leak chasing easier , “knock on wood” no drips now in a few years ....

    Freshly delivered from Walridge, Mike started bringing this over from the UK partly because of Jim's oil tests, impossible to find in NA otherwise

    Now I'd use that if I could grab it without having to leap through flaming hoops in a circus. Alas we poor Americans have to suffer through lesser oils....My faithful road whore really deserves that stuff too for being so good to me...Treating me like pimp daddy all the time.

    Ok so now I'm a lil lost. There's 3 spots to put lubrication? Lol

    Where are the drains and fills for these lubrications?

    My Norton has a oil tank so I assume that's where the engine oil goes....

    Thanks for info guys as I'm a noob to these bikes.

    This is the later (70-on) model workshop manual but it contains more detailed information than the early Commando manual.

    Oil for the engine goes in the oil tank. Oil for the transmission/gearbox goes in via the round inspection port on the right side above the kickstart lever. The gearbox oil level plug is just behind the kickstart lever. It should be removed and oil added until it starts to drip out of the level plug hole. The primary transmission is the large case on the left side that houses the drive chain that connects the engine output gear to the transmission. It gets filled through a large inspection hole near the top of the case and also has an oil level plug low on the case below the foot peg, not to be confused with the center fixing bolt which is pretty much in the center.

    And then there is oil in the front forks, so that is four. And then there is the swingarm pivot, which is number five, but I'm not going into that here!

    PS - if the bike is wet sumped (i.e. the oil has drained from the tank into the crank case) then it needs to be drained before adding more.
