On a related note, where do ya'll buy 5 gallon buckets or small drums of grease to fill your old tubes? I'd like to start doing that if I could save a few bucks.
I like to switch color of general purpose grease. Red, gray, blue, ect, and its easy to tell the old grease (last color) is all pushed out.
Now, if your a good boy, and always grease every time, less of an issue. If you might grease less often then you should, its nice to know you pushed the old out and have it filled with fresh clean grease.
Yes, im guilty of greasing less often then I should, but its not like I Dont grease.
