I'm not sure what the best for your garage door opener is. I don't have a garage door so I never researched it. I just know you don't want to use white lithium spray lubricant.

Most of my experience is with the spray stuff, from many manufacturers. I'm not sure if I've used non-spray stuff.

The only information I have is over 30 years of personal experience with the stuff at home and at work.

Edit:. Actually if you Google "Does white lithium grease dry out" and ignore the articles from the manufacturers of white lithium grease there's plenty of stuff talking about how it dries out.

I've had experience with white lithium since I was 10 years old. I'm over 40 now. I've used it at home and at work. After 5 or so years the stuff is dry and crumbly and sticky. I still have to clean this crap out and relubricate parts at work once in a while because they used it for a few years, as they didn't believe me when I told them not to use it.

No it's not.

White lithium grease solidifies into an anti-lubricant after a few years. Don't use that crap on anything!

Edit: downvote me all you want, then go use white lithium grease. In 5 years when it's a crumbly mess remember me and my laugh lol.

Well since the universe is like 7 billion years old anything in the last 100,000 years is pretty recent.

If you used a 1 inch long wrench and put 7lbs on it's end would that be equivalent?

There's millions or billions or more diamonds buried deep in the earth that will never be found. Probably the majority of them. And the process often makes them imperfect enough to make them almost worthless, except to be ground into abrasive powder.
