WD-40 works great as starting fluid!

We all have at least one can of WD-40 lurking somewhere within our households. Great stuff for fixing almost anything in need of a shot of lubricant. What most people don't know is that WD-40 also works terrific as starting fluid when dealing with that hard to start lawn mower, car, or motorcycle. Just spray some in the carburetor intake and your engine will fire right up - even if it has been sitting for a long time and there's stale gasoline in the carburetor making it reluctant to start.
WD-40's combustible makeup not only helps hard to start engines run, but its light viscosity lubrication also helps to lubricate valve guides and piston rings that are lubrication starved from long periods of non-use.
As with any flammable material, common sense precautions are essential: don't smoke or use WD-40 near an open flame, and do not crank an engine over while spraying WD-40 into the carburetor inlet.

noisy automatic door opener, what can be used to lubricate it

Absolutely! When I had a repairman replace a broken spring, he used WD40 on hinges, rollers and the chain. Worked great. That's what I do now

Engaging reverse gear

If WD-40 helped the problem then the bushes and linkage should be inspected for wear/adjustment and rust as the WD-40 is a temporary lubricant. Check it asap as the problem needs repair.

Pivoting glass shower screen over bath "screams" when moved

You can use WD-40 on the pivoting part, spray a little on the hinge part when the shower door is mostly closed and also mostly open, open and close the shower a few times so the stuff can penetrate it, and Make sure to tighten any loose screws, and brush out any grime using a toothbrush and liquid soap. Wipe the drops of wd-40.

You should be set, cheers!
