I bought this compressor used 25 years ago and have never had a problem with it”, says Robb of Salem Alabama. It’s an old Jacuzzi Bros compressor and wonder what kind of oil does it take?

Figured it was time to check the oil but I don’t know what kind of oil to put in it.
Please help. Thx

Jacuzzi compressor oil
Looks to be a conventional piston pump, so the “compressor oil” at your local big-box store should be fine.

Type of oil for your compressor
Splash lubricated compressor pumps will usually use SAE 30W oil, but you CANNOT use motor oil. Look for a non-detergent, SAE-30 oil (either traditional, or synthetic).
The detergents in motor oil keep debris and contaminant particles suspended, where they can be filtered out by the oil filter. Compressor pumps do not have this, so the particles need to settle to the bottom of the crankcase….non-detergent oil allows that to happen.
If you live in a climate where it’s very cold in the winter (below 30 deg F for long periods of time), and the compressor is located in an area where it will also be that temp, you should change to a SAE 0W-30 during the cold months, then change back to straight SAE-30 during the warm months.
