As a professional organ technician, I've dealt with plenty -- of all shapes and sizes. I *do* admit there could be exceptions, and I welcome further hints, advice, or corrections! Older (generally LARGER) blowers like Spencers and Kinetics run at slower speeds and have large bearings that are perfectly happy with run-of-the-mill 30 weight motor oil. They just want to *have* it!! (and they might tend to use it a bit, if they are getting up in years) Check them regularly and keep 'em full, and they'll keep on going forever. Over-oil them, and they make a mess -- but it doesn't hurt the machine in the least. Some of these beasts, of course, also have fittings requiring grease, but again the operative issue is having some of it in the bearing. = Smaller high-speed blowers (often imported) require more precise lubrication. Their bearings are small and close-tolerance, so improper oiling can more easily "gum up their works". These machines require a medium-to-lightweight high grade machine oil, usually applied in small doses at relatively long intervals. Over-oiling these wastes expensive = oil and also makes a mess...and the dirt that the oily mess attracts is potentially more harmful to the close-tolerance bearings of these = machines. Hope this all helps someone...! Tim Bovard Little Rock AR

The engine additives actually help the bearings because of the coating and anti-oxidation qualities. I tend to avoid multiviscosity oils as they have lighter molecular weight oils in them = that may tend to slowly evaporate off leaving a sticky residue. DO NOT USE 3-in-1 Oil on anything like a motor bearing. It has a paraffin = base that eventually oxidizes and can turn into something akin to = superglue. 3-in-1 on small motors is a bad idea as I have seen motion picture projectors, spring motor Victorolas, and other mechanisms that were all locked up solidly. Sewing machine oil is very light and may be advisable on new blowers. It does not have the heavy paraffin base that hardens. I would contact the manufacturer for better information on each blower. Should the maker not still be in business then a drop of fine machine oil at the indicated = oiling points should not do any harm. I have two contracts with blowers where there are NO points to lubricate. = These are motors with modern "cintered bronze oil impregnated lifetime bearings." My experience with other motors having so-called lifetime bearings is that a drop of fine machine oil where the shaft enters the housing cannot hurt and will prolong the life of the "lifetime" bearing. Motors with grease cups may use automotive wheel bearing grease without = any worries. I normally give my clients blowers so equipped a quarter turn on = the grease cup once a year. Lastly, I like to do what I call the "spin-down test." When I first take over a contract I stand next to the blower and have it shut off from full = RPM no wind being used. I then take a stopwatch to record how long it takes = the blower to spin down and stop. On the Marina Theatre in San Francisco, the = original 1927 Spencer Orgoblo will run down in 1 minute and 24 seconds = (with a belt-driven generator attached!). When the time drops more than a few seconds I give the cups a quarter turn. Why don't I just do this without checking? Well, over lubrication can be damaging also. I figure the = motor has had grease pumped into it since 1927 with no place to go. It must be extremely full by now and I do not want to add any more than is needed. These old machines are really quite forgiving as a fellow who cared for = the organ ahead of me would use Vaseline Petroleum Jelly (which also hardens) = and give the cup a turn every time the organ was infrequently used. Best of wishes to all, Al Sefl Whose opinions above are quaranteed to be 50% correct...........
