Serious question. What do you think about full synthetic transmission fluid as lube? Or an oil with a high zinc concentration?

Thanks for the info. Still new to this hobby but I'm learning! Which Synthetic oil and is this the moly gun grease you're talking about?

Ptfe is good stuff too. The Moly is was talking about is something like Liqui Moly or Tufoil. Tufoil also has a gun based PTFE lube.
The moly stuff is good on contact surfaces like sears and triggers, and the slide of a sem auto. If used correctly and maintained correctly, it won't build up dust like your typical moly grease.
All lubricants will trap dust and debris, just some worse than others. As long as you clean them periodically, it should turn into rubbing compound lol.

I use:
-silicone oil or grease whenever there is an o'ring
-moly paste for metal to metal
I rarely clean my barrels.
Some people really overdo it.

A full synthetic transmission fluid is a thin film lubricant designed to act in a flooded condition creating a gap between parts due to pump pressure and flow.
It is also a low viscosity oil allowing free travel in and through journals and ports.
It's use in an airgun would be very limited as we just don't see those characteristics demonstrated in our needs.
High zinc oils are specific to use as well. The zinc is a powdered solid added due to its inate ability to gall and smear under load, heat and pressure, filling cylinder wall gouges and wear allowing head pressure to return.
In an airgun, this solids package would be wasted and due to interference fitting once the solids are introduced, accelerated wear on soft metals such as aluminum could result.
Generic grease for high pressure pinch points such as a hammer shoulder and seer contact point.
Synthetic non-detergent oil for metal to metal contact.
Molly grease SPARINGLY applied on long slide, low contact hidden parts.

Very good info thank you sir. You can tell my lubrication experience is in automotive lol. Mechanic for many years.

If you want to upgrade your Zelos check out these upgrades from https://www.bravo3d.com/collections/umarex
We have baffles and a hand guard for your bipod attachment.

Not if they dont touch the barrel. My barrel band does not touch the barrel, it has a space of about 1/16 of an inch.

Firewalker has made a few, but they have the bottle conversion.
I have the m60b which is the snowpeak bottle version of the zelos that I cut down. It's 30 cal too.

So I took the Zelos to an indoor range. I sighted in at 25 yards. I shot at 50 yards and it's pretty dead on still. I honestly didn't try too hard at 50 yards due to the other shooters and just didn't expect this good of a group. But I'm ok with it. I'm happy with the 50 yard group. I guess I should have shot at 30 & 40 yards to see if it's still shooting dead on or if I'd have to hold at those ranges. Bottom group is 25 yards. Middle big red dot is 50 yards. Shooting .25 JTS 25.39gr at 915fps.

This is how you can adjust your first stage trigger pull. Remove the hand grip, trigger guard, and another block with two screws. Then you give access to a spring compressed on a rod. Change the compression to change the 1st stage trigger pull. Mine was said way higher than any other gun I've ever used.
Now I wish I knew a way to adjust over travel.
