lucas 4 stroke oil

[notsolow400ex]

Anyone ever use it?? my 450 is due for an oil change and i can get lucas 4 stroke oil from a local shop.

[440ex. ehhh!!]

yep, all the time. i ran it in my 440ex no problems. and i just put it in my 450r on the engine side, good so far.
but before that, i had added some to the tranny side cause i was low, and then the next ride my clutch was slipping and it needed to be changed :s
i dont know if it was the oil that ruined the plates, or just that time.
it was fine in my ex tranny though. so im thinking it was just a coincidence.
i bought a case of this.

just make sure that it does NOT contain
molybdenum for the transmission (clutch side).... you can run moly base oils in the crank side tho

[440ex. ehhh!!]

it doesnt. i ahve checked.
it even says its great for all wet clutch operations.
