To be honest, I have bought the 100% silicon treadmill oil from Amazon for use in lubricating o-rings. Very inexpensive!

@madeintheuk & @PumaCarl - it looks like the pressure has held for about an hour now. I stopped it just touch to the left of the 3000 psi triangle point and it's settled to what I would call "2975" and is holding. Overnight will be the final test. Thank you, gentlemen!

Glad to hear. These guns are built very well, and there’s very little that goes wrong with them.
When it does, they’re super easy to repair!

I have the tools to get into the gun, but to be honest it is shooting very well at the 2000psi reg setting with the JSB 25.36g pellets and I hate to "tinker" it into shooting worse! But as we all know, the tinkerer always wins over time! LOL

When I first got mine the foster fitting was loose. A simple tightening and things were normal.
And yes use the lubricant Tom suggests. I used a basic o-ring lube and it caused issues with my cylinder.

Confirming that the pressure is holding steady overnight! Problem solved. Thanks again to everyone!

I took the Evol out to the range today and it is back to normal. Got 30 rounds out of it before it settled down at the 2000 psi level (my reg is set at 2000 psi). I shot the JST 18gr pellets and this thing is a monster with them. I'm going to set it up for some night ratting. It may be a bit too high powered, but all the shooting is outside with a great backstop and a open acreage. I really enjoy this gun.

With my 15" I had it was at 880fps with the 25gr MRDs. I think around 1000fps with 18gr. Dropped reg to 1500psi then tuned for 870fps with 18gr and got 110 shots per fill. You lose alot of efficiency with the 18gr over the 25gr when tuned for them.
