    I'm thinking about using Chemlube 751 or 501 , the 751 is sae 40wt. and the 501 is sae 30wt. I'm getting my new compressor this week and want to start off on the right foot with the right oil . Does anyone know what ISO the oil should be ? Thanks and sorry to open this can of worms again but there are a lot of different opinions . I think I would be OK using a good synthetic made for high pressure compressors but let me know what you use.

    I've always used 751 in my Yong Heng and it's worked well for a long time now.

    ISO 46 may no longer be recommended although I used it for a year without failure.   I am currently using the Husky Brand Synthetic or synthetic blend oil, found at Home Depot, for two years now without a problem.  Top it off to the red circle in the sight glass.  This oil is clear so you can see when it gets contaminated.

    After some werq on my YH I fergot to put any oil in it and ran it for several minutes without any.  It actually survived the ordeal likely because of the oil it had in it prior.

    Biohazardman, The specs on the Husky look fine and the price even better. And looks to be full synthetic too.

    They have the full synthetic and the synthetic blend stuff as well.  I have used both it has the synthetic blend in it now as that is what they had when I needed it. There are plenty of good non detergent oils out there that likely will werq fine.

           I switched to Chemlube 751 after using the royal purple for about an hour. I pulled the front cover when I switched, and it had a odd smell, almost like cordite which may have indicated detonation with the royal purple? I’ll pull the cover again at the next oil change and give it a smell. I have not experienced stink air as some report.

    lol another oil thread … i got the royal purple because thats what came up on the suggestions on amazon when i ordered it and i didnt feel like looking around … i would definitely worry about heat, moisture and what kind of duty cycle you inflict on it and pretty much not worry about the oil, its going to have very little to do with how long it lasts as long as its the proper type .. maybe change it occasionally if your skeerd .. trust me it wont save it from improper treatment ..

    Thanks guys for all the replies , interesting to see the different oils used and I'm sure all are good as noted by their users. Just got my compressor yesterday so I'm getting it set up.

    Well I ordered some Chemlube 751 so got that coming, but I do have a qt. of Husky full synthetic if I want to start it up before I get the 751. Then when I do the first oil change I would put in the 751. Now my next thing is to use distilled water or not ? Any thoughts ?

    Your best option is soft water but not distilled as the purity of distilled can cause erosion, soft water is free of the calcium and magnesium that causes scale to form, but not so pure as to cause erosion of the cooling jacket and fittings.

    Tracker, Thanks so much for that info I appreciate it very much, just so happens that I have soft water.

    The best oil I've seen is the husky synthetic or the royal purple. The ISO 46 and AW46 hydraulic oils are recommended and do a great job but when filling large bottles or running your compressor extended periods of time your compressor will stink the place up with hot hydraulic oil smells.

    Why not use "antifreeze" with additives to prevent corrosion? Most cars have aluminum blocks cuz they are lighter and aluminum transmits heat (out), better than cast iron.

    Just curious…..

    Antifreeze doesn't pull out heat as well as water alone does, and it does even better when a water wetter is used to help break surface tension.

    I use NuVair 751 and a little antifreeze in the coolant.

    I don't see any problem with using a very small amount of coolant, I just wouldn't add very much. Between a little coolant and Red Line water wetter, it will help prevent algae from forming in the cooling bucket as well as limit corrosion of the aluminum parts. ( for those who don't change the water each time)

    As a side note, I started out using the full synthetic Husky compressor oil in my YH when it was new, but after experiencing detonation and a broken 2nd stage piston, I moved to a better oil. Yall do as you like, no Royal Purple or Huskey for me, and I no longer get the crackling sound I used to get when I used the Huskey. YMMV.
