Breaking in compressor

[Lobi]

So my YH arrived today. I kind of expected it to come with oil but no.
From reading her at AN I'm leaning towards the Seco500.
Manual of course does not mention break in and says 50 hours for first oil change. Sounds like many change their oil the first time at an hour or less run time. What to use for break in oil?
I think I read @12oz for fill (?)

I've had my YH for a few years, I'm using SECO500 now. I didn't use anything different. On my backup that I haven't started yet, I'll put the SECO in it and allow it to just run under a light load for a while (To get the temp up) and then put it under full load.
That's my plan at least.

I used seco for break in too although I changed it at around the 2 hour mark.
It wasn’t discolored until that point.

Why would you introduce 2 different oils? Seco is breathing air specific. Not that the yong heng makes breathing air but plenty of people find carbon deposits on the piston during a rebuild. Shouldn’t happen with Seco lube.

Order it from the place in florida, they’ll ship it fast and well packed.

Forgot to mention, I'm assuming most are using a 5 gallon pails for cooling water. The supplied silicone tuning fits super tight on the male end of a standard 3/8 quick disconnect (picture below) so I plan on sticking a couple of these thru the side of the water pail. Is a filter necessary for the return water?

Some, including race car engine builders, use a different break in oil to seat rings etc. I don't know anything about the piston, cylinder wall, or piston rings in these compressors. Maybe it's not needed.

I'm running Secolube in my YH and changed oil after filling a 74cuft tank from zero. The oil was very dark. I let it run for a few minutes before closing the valves. Gave it a ~15min break every 100bar, never got above 50c. Fill should be to the top of the red dot.

Lobi,
Two years ago, when mine came, I followed advice of Biohazardman and used Husky Synthetic Blend Air Compressor oil for one hour break-in, then switched to Husky Full Synthetic Air Compressor Oil full time. Since then, Bio determined the higher flash point of SecoLube500 (520-degrees F) was more appropriate for HPA compressors than the 460-degree F flash point of Husky Full Synthetic. Recently purchased a quart of SecoLube500 for $37 from Filtertechs, @ 10 ounces per fill will handle three annual oil changes. Here's my set-up, everything is permanent except stool, 5-gallon bucket, hoses and water pump, they get broken down after each session. Toss water in washing machine on wash day, no children in household so no drowning danger. Twist tie hoses to bucket handle, return line tends to slip out. No filter for return line, make sure water pump adjustable rear screen is wide open. WM

I always fill oil to top of red dot in indicator. Did my first oil change when oil (Royal Purple) got too dark to read gauge, about an hour. I'm using Husky full synthetic, non detergent oil now & it works great but will go to Seco on the next oil change. Treat your YH gently & patiently. Read Biohazardman's YH "bible" & follow the suggestions & it should do you right.

What size batteries for temp display?
Anyone remember?
Oh, also, supplied whip has quick connect to fit two of my guns. I'll have to fabricate another fitting for the probe-filled gun I guess.

Batteries: 357 (preferred) or L44. You'll need this adapter for fill probe. (Amazon, Pyramyd Air, eBay) About $10.

Sure, I get this but the oils are the same makeup being you don’t have compatibility issues between oils.

Does Seco lube mix with husky oil? Are they made from the same base material? I Don’t know and honestly I don’t need to know. I made it simple and used seco from the start.

When switching oils, especially oils of different makeup, I would think a thorough flushing of the system would be useful. Don’t want them mixing together and turning to sludge like dex cool and standard green antifreeze do.

Most likely you’ll be just fine no matter what you use. Obviously it’s worked for others.
