I have on hand what seems to me to be a pretty decent grease to lube a springer coil spring with but I've never worked on a coiled spring springer before. My only other springers are gas-springs. If this is acceptable I'd rather use it than spend $ on an airgun specific tar since they're not cheap, at least once you add on shipping, and considering I'll most likely be doing only this one gun. The grease is:
SuperTech Extreme Pressure Multi-Duty Complex Hi-Temp Grease and it is reddish in color. It also says under specs: Base Type-Lithium Complex, Color-Red, N.L.G.I.-Grade 2, Drop Point-500 degrees F Minimum and Timken OK Load 55 Minimum.
It's sold at Walmart https://www.walmart.com/ip/Super-Tech-Multi-Duty-Complex-Hi-Temp-Grease-14-oz/16795246 (https://www.walmart.com/ip/Super-Tech-Multi-Duty-Complex-Hi-Temp-Grease-14-oz/16795246) and Mike Ellingsworth (Mr. Stepingstone on YouTube) really likes it for triggers, but I can't recall if he liked it for coil springs.
I'm getting ready to do a lube tune and have never done one before on a coiled spring gun. My understanding is you don't need to get a lot of lube on the spring, but you want some Seems like this will suffice. Will it?
I plan to use moly grease on the ends of the coil spring after I sand them smooth, and moly would be the choice on the piston seal and piston (light touch). Thanks!

The purpose of tar is to dampen spring twang more than to lubricate anything. If the red grease is thick, sticky, and stable so it doesn't fling off or run out of the cocking slot, it sounds like it would work ok. I believe the "tune in a tube" product is some sort of tacky red grease.
Have fun!

Now that you mention it, I've heard that before. Thanks! Is the grease (or tar) supposed to be smeared on very lightly, or kind of thick? My recently acquired RWS 34P does seem to have a wee bit of lube in the spring area so I was thinking light lube is the way to go. The reason I ask about this is I've been thinking about taking it apart to polish the spring ends and put a soda bottle sleeve in the piston.

Springs really don't need lubrication ... but do like ( We like ) there vibration being minimal. Tars are used to DAMP this vibration the same way as fitted / snug spring guides do for the end result of a smooth and quiet shot cycle.
there is much more in play in a spring piston air gun than the lubricant or damping compound on the spring ... tho each has a cause & effect pending the set up/configuration.

I'll agree with Dan. I've used Sta-Lube disc brake and bearing grease. It's kind of thick and sticky and I just kind of string it from coil to coil. In use the spring does fling it off but it also dampens twang. If you ordered the 34P be prepared for some twang anyhow - the stock seems to resonate. That's the only gun I've got on which I've actually used Maccari's tar (which seems to be just a really thick grease). I had a container which came with one of his spring kits which I used on another gun, I didn't specifically order it for my 34P. Just remember to be safe and use a spring compressor when you dismantle the Diana. Avoid surprises.

I mailed a request over a year ago for the MSDS for Tune in a Tube (TIAT). Here’s what I found:
Tune In A Tube is Almagard® Vari-Purpose Lubricant. It is a lithium complex formulation, red in color. It’s distributed by LEI (Lubrication Engineers, Inc.). This is the same company who supplies Crosman Pellgunoil.
Cost then for a 14.5 ounce tube of Grade 2 from Speedway/eBay was $17.98 delivered (GA tax).

More grease will dampen more vibration, but will rob some velocity. You can start light and put more on if you need it. If you don't mind the velocity loss, you can go heavy from the start.
Once you get used to it, you can have the spring out and back into a 34 in less than 10 minutes.

The gun does have a small amount of lubrication in the spring area, it's not bone dry like some have reported. I suppose it is all that is needed because there is no honking when cocking. The barrel is slightly snug when returning to the closed position, not bad at all. I suppose there is no reason to lube tune except for the fact that I can't stand the vibration when I shoot.
My only other guns are two gas spring breakbarrels and 4 multi-stroke pneumatics so I am not used to spring twang and I don’t like it. It’s just a major turnoff.
Some say it’s because of the hollow stock and some say it will go away if you polish the spring ends and do the plastic sleeve inside piston. Maybe it requires both?
Is it unrealistic to think I can get it to be as smooth as a gas spring rifle?
I suppose the easiest thing to do first would be to stuff the stock with pellet packing material and soft bed the gun, then if that doesn’t do it I could go in to polish the spring ends and install a plastic sleeve?
If I don’t do anything do you think I can still return the gun even though I shot 12 to 14 pellets through it?
I know I’d pay for the shipping if the only reason for returning is buyers remorse but does that option go out the window once you’ve sent a few pellets down the barrel? Thanks.

It's very realistic to say that a reasonable tune on a spring gun can be as smooth a shot cycle as a NP type gun. I've done it several times. With reasonably fitted spring guides, top hat, and moly or Krytox on thee piston area, and a light coating of spring tar, it will be pretty nice. The last gun that I did was an XS-25, that went from a buzzer to a thunker. No sign of any spring buzz, just a faint metallic ring (faint bell) after the shot, which could also be there with an NP type gun.
I would say no to the high temp grease you linked to before. It looks more like something that would be used for wheel bearings. The High Temp rating doesn't mean anything for airgun applications. It may be cheap, but if it doesn't work, you've wasted your money.

I just did a Winchester 1100 with a hollow stock. The very first thing I did was stuff the stock,as tightly as possible (I used rags) to get rid of the hollow sound.
I took this apart(devil of a time getting it back together) and inspected the innards. Everything was fine.
I have some kind of wheel bearing grease said to have some moly in it. hmmm not good.
This thing honked when cocked, twanged,and vibrated.
I gambled, and tried the Tune in a Tube. Eureka! this is quiet now when cocking, and all I get is a thump when I shoot.
This was a $59 gun from Wally world. and I'm probably trying to make a "Silk Purse" from a sow's rear, but it's a hard shooter.
That little tube worked fine,and I have enough for other "projects" You only use sparingly.
Thanks Mark for the MSDS. I was wondering about that.
