  • Another Oil Thread, but for Air Compressor Oil

    I have a small 3/4 H.P. 4 cylinder Craftsman air compressor that I bought at an auction a few years ago. I'll be changing oil for the first time since I bought it. It's too hard to get running when the temp gets below 55 degrees, so I need a lighter oil. I've always read that air compressors should use non detergent oil, as the detergent oil leaves the valves with a residue. I did a Google search for the best air compressor oil to use, and there was a wide variety of opinions, along with some sound information. It seems Mobil 1 synthetic oil is also OK to use, so I'll try a light weight of that, as my compressor sets out in the cold.

    This compressor has 4 very small pistons, so it gives a nice even flow and is very quiet running. I believe it was sold mainly for spray painting, and should not be run any higher than about 75 PSI. I think it was made in the 50's or 60's.

    I know people that run a lighter weight detergent oil in their compressors and they hold up fine.

      I agree with Mitch, I think the most important thing is to be sure it has oil, and there is nothing wrong with a lighter oil year round.
      You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

        Choosing a motor oil can make your head spin. Here's a link to just Mobil 1 synthetic, let alone all the other oils Mobil sells. I think they even have a special oil if your car has just push button tuning, instead of signal seeking. This is nuts trying to figure out what oil a person should use. I thought Mobil 1, then pick the weight you want, if you choose synthetic, but there are 10 different Mobil1 oils in this link, plus Mobil now sells other full synthetic oils that aren't called Mobil1.

          Always use the flavored spec the car calls for.

        A good friend of mine is/was one of the head plant engineers for Beuller Corp and has built dozens of large (we're talking in excess of 100k sq ft) diecast and foundry operations before he started his consulting business. He swears by using Mobil1 10w30 motor oil in his compressors. I switched to this a good 20 years ago and have never yet been disappointed. My compressors run a bit quieter as well which is a bonus..

          Favorite oil for hand held oil can?
          by rrich1
          What oil do you use for a hand held oil can to lube the various parts on the model A? Also do you use an antique oiler or a new one? The ladder is more curiosity than anything....

          Switching to synthetic oil
          by Michael M
          So as not to hijack the other oil thread on here, I thought I would ask a new question in a new thread.

          It seems conventional wisdom says you can mix conventional oil and synthetic. Its also been reported that conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.

          It's also a given that a quart or more oil stays in the tray...

          Type of Oil - Zinc additives - brands?
          by EJR8402
          I need to do an oil change on my '59 T-Bird with the 352 V8. I've done some research about the type of oil needed and it seems that these old flat tappet cammed engines should probably have oil with zinc additives.

          The prior owner of the car just recommended plain old motor oil, 10W-30. I'm sure that's fine if it's barely driven, but I do want to get it out a bit.

          So what...

          Would anyone know of a clear oil?

          No color to it.

          Oil change again and probably again
          by Blown Gasket
          I changed my oil today but did not pour any oil down the distributor hole as many claim they do. I have read, looked at pictures and diagrams but fail to understand the logic behind it. To me the oil would go around and down the shaft, over the pump and into the sump. Oil poured into the crankcase tube goes to the same place. If changing oil removes oil from the upper valve chamber so would letting...

          Oil change interval observations and comments
          by tbirdtbird
          This applies to both Model As and moderns.
          I think most everyone on this forum would not let their oil go past 3000 miles on their A before changing, at least I hope so. Sooner if the car only gets short runs.
          There are numerous additives, anti-wear and such, that do get depleted.

          As far as moderns, there is a trend to extend the interval out to 7500 and beyond.
          It is...
