Hi Fellas and Lasses, Is it possible to use 140 weight gear oil in the swivel housings rather than one shot grease applications? I'ze only askin' coz I'ze got 25L. of Mobil EP140 gear oil from a previous job a coupla years ago, I've checked it and oil is still ok. Many thanks for the machine-gun fire and flames, if it's a no-no.
