I bought my first gun in the early 80's and basically put grease in it. I recall it being black at the time. That was a time when cars and trucks had grease fittings for the suspension and steering. Chassis and steering points were what you greased back then; that time is gone. Rolling the clock forward some 35 years, I've been using red Lithium complex grease for the lawn toys. The last fill on that gun was Lucas Red 'N Tacky. Maybe it was two tubes - I don't recall. What I do know is that the Lucas RNT leaks a lot of oil from the gun, so I bought new gun and filled it with another grease, rather than toss a full load of RNT from the original gun. Now I have a NGLI #2 GC-LB High Temperature grease in the in the new gun. Should I just toss the old gun once the Lucas RNT is gone, or is there a different grease that a homeowner in the Northeast might consider?
