Bill, you want to careful with 3 in 1. It comes in several formulations and can colors.
The one you want to use is 3-in-1 ELECTRIC MOTOR OIL. It will say so on the label. It has the prooerties to remain and lubricate the bearings under high speed temperatures and will not glaze. Do NOT use the 3-in-1 common kitchen oil best suited to squeaky hinges. Sewing Machine oil, btw, is too thin for motors and is meant for sliding metal parts, which a sewing machine abounds with. Never use silicon-based WD-40 on anything other than as a rust corrosion releaser or quick fix for hinges. Never never in a bearing or axle. Dave This post was last edited 01/26/2013 at 10:14 |

WD-40 is the trademark name of a penetrating oil and water-displacing spray. It was developed in 1953 by Norm Larsen, founder of the Rocket Chemical Company, in San Diego, California. WD-40, abbreviated from the phrase "Water Displacement, 40th formula,"[1] was originally designed to repel water and prevent corrosion,[2] and later was found to have numerous household uses.
Larsen was attempting to create a formula to prevent corrosion in nuclear missiles, by displacing the standing water that causes it. He claims he arrived at a successful formula on his 40th attempt.[2] WD-40 is primarily composed of various hydrocarbons. WD-40 was first used by Convair to protect the outer skin, and more importantly, the paper thin "balloon tanks" of the Atlas missile from rust and corrosion.[2][3] These stainless steel fuel tanks were so thin that, when empty, they had to be kept inflated with nitrogen gas to prevent their collapse. WD-40 first became commercially available on store shelves in San Diego in 1958. ------------------------------------------ 5 actually useful Things To Do with WD-40: WD-40 has been around for more than 50 years. The product that was originally meant to be a rust-prevention solvent has grown to become a useful household product with hundreds of different applications. Here's 5 of the many ways to use this diverse item. From Extraordinary Uses for Ordinary Things, Reader's Digest Australia Did You Know? WD-40 made its way to the home market in 1958. The idea was inspired by employees who snuck cans out of the plant to use at home. Caution: Do not use WD-40 near an open flame, heat source or electrical currents. Don't place the can in direct sunlight or on hot surfaces. Be sure to use WD-40 in well-ventilated areas and never swallow or inhale it. 1. Winterproof Boots and Shoes Waterproof your winter boots and shoes by giving them a coat of WD-40. It’ll act as a barrier so water can’t penetrate the material. Also use WD-40 to remove ugly salt stains from boots and shoes during the winter months. Just spray WD-40 onto the stains and wipe with a clean rag. Your boots and shoes will look almost as good as new. 2. Clean Your Fridge When soap and water can’t get rid of old bits of food stuck in and around your refrigerator, it’s time to reach for the WD-40. After clearing all foodstuffs from the areas to be treated, spray a small amount of WD-40 on each resistant spot. Then wipe them away with a rag or sponge. Make sure you wash off all the WD-40 before returning food to the fridge. 3. Renew Faded Plastic Furniture Bring colour and shine back to faded plastic patio furniture. Simply spray WD-40 directly on the surface and wipe with a clean, dry cloth. You’ll be surprised at the results. 4. Exterminate Roaches and Repel Insects Don’t let cockroaches, insects, or spiders get the upper hand in your home. - Keep a can of WD-40 handy, and when you see a roach, spray a small amount directly on it for an instant kill. - To keep insects and spiders out of your home, spray WD-40 on windowsills and frames, screens, and door frames. Be careful not to inhale the fumes when you spray and do not do this at all if you have babies or small children at home. 5. Keep Animals from Flowerbeds Animals just love to play in your garden, digging up your favourite plants you worked so hard to grow. What animals don’t love is the smell of WD-40. To keep the animals out and your flowers looking beautiful all season, spray WD-40 evenly over the flowerbeds one or more times over the course of the season.

I have a close friend who owns a vac repair/sales shop, he said to use 3 in 1 electric motor oil (in the blue and white bottle)..I believe you know him as well, Dave. SAE 30 will only gum up the bearing, and eventually cause it to go fail. I'd take his advice on this topic as he has been servicing and overhauling vintage vacuums for the majority of his life. SAE 30 is great for a lawn mower, but not so much for an electric cleaner. I cannot imagine why one would put engine oil into an electric motor.

Well, Louvac, if that is what you choose to use in your motors, great! As aforementioned, I have a very close friend who owns and operates a vacuum shop. He learned from a man who was trained by the Hoover company. He also services Royal appliances... I wouldn't put much faith in anything "TTI" says about servicing, as service really isn't their foremost concern. I think I will stick to the advice of my friend in New York. Glad that SAE 30 is working for you! :)

I know this is an old thread but I just wanted to add useful information to it because I came across this thread in Google and others might too.
What hooverboy81 didn't understand in Louvac's comment is that there is two types of motor oils, one for gasoline motors, one for electric motors. You use SAE-30 detergent oil in gasoline motors, and then they make a separate SAE-30 oil that is non-detergent for lubrication of electric motors. The bottle will specifically state on it "not for gasoline engines" and sometimes it might have a photo of an electric motor on the label. I got mine at Walmart: www.walmart.com/ip/Super-... You can use it in any electric motor large or small, but 30-weight is good for high RPM motors like HVAC blower motors and large fans, or vacuum cleaners, since they run for extended periods. 30-weight N.D. oil works great because it will still hold itself together and lubricate without being sloughed-off the motor shaft under speed and risk losing lubrication. Non-detergent motor oil is typically recommended for lubricating electric motors that do not have sealed bearings and for lubricating bronze sleeve bearings. Non-detergent is usually specified in electric motor manuals - even for modern electric motors. This is why Royal and TTI use it because their vacuums are marketed mainly for industrial use and are used for hours upon hours a day, nearly non-stop. You need to use a slightly heavier oil so it doesn't burn up with friction. Here's a photo I took of the care label on a furnace motor from the 60s or 70s that I got for $4.50.
