Lube King LU01302G offers 2 gal of SAE 30W non-detergent oil with no additives. It may suit equipment whose instructions call for that amount, viscosity and formulation.

The product is described as motor oil for applications that call for non-detergent oil. It is not specifically described as compressor oil, so verify that your compressor maker permits it before using it.

Lube King cautions that the oil is not suitable for most gasoline-powered engines built after 1930. Keep its use within the equipment's stated oil requirements.

How do you choose air compressor oil non detergent?

Choose non-detergent compressor oil by matching the manual's required oil type and viscosity, then check that the product is intended for your compressor style. SAE 30 alone may not meet every requirement.

Start with the compressor model and manual. For model-specific recommendations, see Rolair air compressor oil options.

Check whether the machine uses oil, the required viscosity grade, whether synthetic oil is allowed, and how often the oil should be changed.

A reciprocating compressor may have different needs from a rotary screw or vane compressor. TRIAX is labeled for several compressor types, while Milton is described for oil-lubricated reciprocating compressors.

Don't choose an oil based only on the words “non-detergent.” Confirm the grade and equipment fit, and avoid mixing oils unless the compressor maker allows it.

What do SAE 30 and ISO 100 tell you?

SAE 30 and ISO 100 are viscosity labels used by products in this roundup, but you should follow the grade your compressor manual specifies. Several picks state both grades, while others give only one.

Milton lists ISO 100 and SAE 30W, and TRIAX lists ISO 100 and SAE 30. MAG 1 is identified as SAE 30, while ComStar is SAE 20 and AGMA #2.

These labels don't prove that oils are interchangeable. If the manual gives a particular standard or viscosity, choose a product that states it clearly.

Can you use motor oil as compressor oil?

Use motor oil in a compressor only when its manufacturer says that oil is suitable. Lube King SAE 30W non-detergent motor oil may match some requirements, but its intended uses don't make it a universal compressor lubricant.

Compressor design, operating temperature and lubrication points all affect oil choice. A similar viscosity doesn't mean two oils have the same intended use.

If you are unsure whether your compressor needs oil, see Can You Use an Air Compressor without Oil?. For oil-filled models, follow the manufacturer's fill and service steps in How to Oil an Air Compressor?.

Which non detergent compressor oil should you pick?

Pick Milton 1002 if your oil-lubricated reciprocating compressor calls for non-detergent ISO 100 or SAE 30W oil. Choose TRIAX if you need a synthetic option and your manual allows it, or MAG 1 when SAE 30 non-detergent oil matches the stated requirement.

For bearing or pressure washer pump applications, use ComStar or AR Blue Clean only when the specific equipment instructions call for them. Match the oil's grade, formulation and intended use to your manual.

Frequently asked questions

What does non-detergent air compressor oil mean?

Non-detergent oil lacks detergent additives used in some engine oils. Some compressors require it, so check your manual for the exact formulation and viscosity before filling or changing the oil.

Do not assume that every non-detergent oil is suitable for every compressor.

Can I use SAE 30 non-detergent oil in my compressor?

Use SAE 30 non-detergent oil only if your compressor manual specifies or permits that grade. A matching viscosity alone does not confirm that the oil is right for the compressor type or operating conditions.

Check the maintenance section of the manual before you buy.

Is synthetic non-detergent compressor oil suitable?

It can be suitable when the compressor maker permits the oil's formulation and viscosity. TRIAX Kompressor is labeled full synthetic, non-detergent, ISO 100 and SAE 30, but that does not override your compressor's manual.

Check before changing from conventional to synthetic oil.

Can pressure washer pump oil go in an air compressor?

Do not assume pressure washer pump oil is suitable for an air compressor. AR Blue Clean PW64516 is formulated for plunger pumps, including specified pressure washer models.

Use it only in equipment whose manual confirms compatibility.
