What Is the Difference Between Air Compressor Oil & Motor Oil?

An air compressor is a versatile tool that can be used for inflating tires or running pneumatic tools Between Air Compressor Oil & Motor Oil. Most kinds of compressors require oil, but there are key differences between air-compressor oil and motor oil.

Air Compressor Oil

Air-compressor oil is usually a synthetic oil that does not contain detergents commonly found in motor oil. A synthetic oil also helps reduce carbon deposits within the compressor.

Motor Oil

Unlike air-compressor oil, motor oil often contains additives that help protect engines by preventing the oil from deteriorating under high operating temperatures.


While it’s possible to use a motor oil in some air compressors, it is not generally recommended that air-compressor oil be used in motor vehicles. Refer to owners manuals for the recommended oil types for each application.

What Oil Should Be Used in a John Deere Riding Mower?

John Deere riding mowers have gasoline-powered engines and are intended for residential mowing. The company refers to its larger mowers — which may be used for residential or commercial applications — as lawn tractors. These units have either gasoline or diesel engines. John Deere recommends consulting your riding mower owner’s manual for the exact type of recommended oil. A knowledge of oil viscosity can help guide you, however.

A 10W-30 weight engine oil is viscous even at temperatures as low as negative 4 degrees Fahrenheit. For climates where temperatures do not plunge below zero, John Deere says that 15W-40 oil “provides the best engine performance and protection” for temperatures that do not go below 5 degrees Fahrenheit. For those people living in colder climates, 5W-30 oil works well in weather between negative 22 degrees and 104 degrees Fahrenheit.

John Deere Oils

John Deere recommends the use of its own brands of engine oil. The company explains that its oils have additives and performance enhancers that reduce corrosion and keep internal engine parts running cleaner. Other brands of engine oil will also work well provided they prevent sludge, resist foaming and perform within the indicated temperature ranges in addition to reducing corrosion while cooling and lubricating internal engine parts Read more
