Difference between EZ-Lube types?

[Wren59]

I'm trying to decide which of the three EZ-Lube types to buy (I can't really afford multiple at once) should I go for the light EZ-Lube or the heavy EZ-Lube? all of my engines have very simple valve gear, and don't have a lot of exterior moving parts.

all feedback is appreciated!

There are different types of lubricants because there are many types of applications and one size does not fit all.9

Gears and axles want a grease type lubricant that won't run all over the place.  Steam locomotive running gear wants a molecule sized droplet on each of the points.  So molecular that a leprechaun could not see it with a microscope.  It is very easy to over-lubricate and eventually see it run all over everything.  I've done it and the cleanup is not only difficult, it's never really 100%.

thats understandable for sure, but which should I use for lubricating the wormdrive?

The "worm" is part of a gear train.    Use a light grease.  Liquid oil will spin off the spinning worm and will run all over the place.  And make a mess impossible to completely clean.  Believe me. I have made this mistake.
