Yong Heng after piston replacement

lol
:) I am a large volume shooter and topping up 3 of these 14L bottles at a time of a work party.
The vibration meter battery died at about 68 hrs and occasionally coming up with some numbers ups and down, and can't care replacing it.
What is a total time on the compressor I don't know anymore, it works, and whenever the fill start slowing down I just replace the pistons right away and that is about ones a year at least. But I have four BNIB kits in my drawers for spares.
The last oil change I did last summer.
But I am watching the Temps very closely.
The Temp is a piston rings killer.

I read 3 -14L tanks . I thought, what tank is 14L 😂
 
BigHUN, I see the bottle of Super Lube o-ring goo there, good stuff, I shoot it into the piston housing of my Vevor box every half-hour of run time, it's kept it from dying I think. I use a syringe with a large bore needle with the sharp ground off.

But you missed the point of my previous comment. Mobil 1 turbo (kompressor) oil is not air compressor oil, nor should automotive motor oil ever be used in a high pressure system. The standard here is ISO 46 type air compressor oils, preferably something with a high pressure lubricant additive. Nor should you run a detergent oil, which won't allow the water and sludge to separate in the oil and drain to the sump.

Read up on high pressure compressor oils and the ISO 46 standard that Yong Heng recommends, because Mobil 1 isn't one of them. I think you're getting excessive wear and perhaps even detonation in the piston, that's why they're going out. You'd be much better off running something like Amsoil compressor oil, which has no detergent, has high pressure lubricant added, and a much higher flashpoint than Mobil 1.
