Yong Heng after piston replacement

:) 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.

I have tried couple oils in the past. This Mobil one is a twin turbo rated = high RPM high Temp.
I am using it second year.
The oil - any oil, shall lube the 1st stage piston cast iron rings, but shall never reach to second stage high pressure piston composite rings. If does, there will be carbon build up on that piston and eventually degrade the composite ring life.

Detergent motor oil is inappropriate for any air compressor system. That's why you keep having to replace pistons. You need to run an ISO 46 approved compressor oil, that's not me saying that, that's every air compressor manufacturer in the world saying that, including Yong Heng.

I'm pretty sure Yong Heng stopped using ISO 46 oil, years ago. It stinks and builds up carbon.
SECO 500 is a better option.

You appear to say that ISO 46 is a brand of oil? No, ISO 46 refers to the global engineering standard for oil quality recommended by ALL air compressor manufacturers, including Yong Heng.

Yong Heng used to call for using AW ISO 46 Hydraulic oil. They don't anymore.

If you are saying any ISO 46 oil is suitable, you are being too vague.

No, I'm not being too vague, I've said here repeatedly that ISO 46 is the correct oil type, because that's in fact the correct type. And nowhere does Yong Heng say that detergent motor oil is the correct oil, nor do they specify Seco 500. There's nothing vague in any of that.

This has always been been a contentious subject. Some claim great luck with any compressor oil, or Husky synthetic compressor oil. I ran Royal Purple in my YongHeng, as recommended at first, but it literally stunk, built carbon on the HP piston and was obviously not up to the task. I’ve since run proper high pressure breathing air compressor oil, in both my YongHeng and my big compressor. The YongHeng no longer stinks up the air, stays cleaner and doesn’t build carbon. The oil is pricey, but goes a long way and gives some additional peace of mind. We ask a lot of these machines, and pay a lot for some of them, good oil is necessary insurance.
