Wonder what Shell SB2628 Grease is? Not on Shell's website. They suggested that I look for 222628. I did. They don't have that on their site either (curious). Googled for it, no luck. Of course, I'm still using grease from a 1 lb. can that I bought from Sears back in the late sixties. Maybe SB2628 is vintage as well? Bob Johnson BJ8
