    I think you are looking for an M10x1.0 thread.

    You can get an adapter at any decent auto parts store to adapt the M10x1 to the 1/8 NPT thread common in the US.

    This is a common issue in the land vehicle world.

    The two threads are so close that cross threading is a common mistake.

    1/8 MPT = 0.405"x 27 TPI

    M!0x1 = 0.394 x 25.4 TPI

    It is only a   0.011"  and 1.6TPI

    The 1/8 will hand thread into the M10 for 3-5 turns before it starts to bind.

    Some people have successfully rethreaded the 1/8 into an M10 by just running an M10 Die over it.

    But you didn't hear that from me!

    My latest update regarding this issue.

    I found a 300ºF (150ºC) sensor with the M10x1.5 thread pattern at a VDO vendor in Holland called VDO Webshop. Over there the part number is:

    VDO 323-801-010-001D

    It might also be listed this way:

    Continental VDO A2C1755400001

    I ordered a couple of them at about $35 each (the deal is in Euros) and they should arrive in a few days.

    While I was searching for this, Bjorn at AVMap confirmed both the need for a 300ºF/150ºC sensor and the 13 digit "euro" part number shown above.

    I think now I will at least be getting true temperature indications after which I can finally tell for sure if I have low oil temps.
