My garage door opener has been making a lot of noise lately. It was unable to lift the door more than a couple inches and I thought it was about to fail. There was grease on the lead screw, so I didn’t think it needed lubrication.I saw your oil sample on my toolbox so I thought I’d give it a try. I liked that the lube stuck to the screw without dripping on the garage floor. Then I pushed the garage door opener button and was blown away – the opener was nearly silent and opened all the way effortlessly. It sounds like the motor is working a fraction of how hard it was previously. You saved me $300 on a new garage door opener.
