    Bought the recommended oil but instructions state add 5/8 quart (600ml) so tried to add the whole bottle but this overfilled so not sure whats going on just be aware.

    Ok. But this is a 600ml bottle for the same price as 1ltr from local motor factors.

    It’s oil, pretty basic stuff but needed in this quantity to carry out the chipper’s oil change. Probably could have got it cheaper elsewhere, but as I wanted some other spares I combined the order. Very quick processing of the order.

Q & A

Which is the correct oil for the FM6DD-MUL? The website and info says 10w 40, however the tags all over the motor state 10w 30. Nic Watson asked on March 4, 2023

Both 10W-40 and 10W-30 are perfectly suitable for this machine with no upside or downside to either.
