CP Genoil Engine Performance 15W-40 is Chicago Pneumatics mineral-based engine oil for diesel and gasoline engines, supplied in the 5.3 gallon size. Meeting or exceeding API CI-4 Plus/SL, it suits modern diesels including EGR-equipped engines and covers heavy trucks, construction equipment, agricultural machinery and marine engines with dependable cold-start flow and high-temperature stability across a broad operating range.
Detergents and dispersants keep components clean while anti-wear additives protect under load, so one oil serves a mixed fleet. Run it in the drive engines, then pick up Genoil M compressor oil for the compressor itself; both sit in our oil and lubricants section alongside supplies for Chicago Pneumatic air compressors and other engine-driven equipment.

Can I run Genoil 15W-40 in both diesel and gasoline engines?
Yes it meets or exceeds API CI-4 Plus/SL, covering heavy-duty diesels, EGR-equipped engines, and light-duty diesel and gasoline engines that call for a 15W-40.
Is this the right oil for the compressor airend?
No Genoil Engine Performance lubricates the drive engine. The compressor element takes Genoil M compressor oil, sold separately in the same 5.3 gallon size.
Can I use it in my breaker or rock drill?
No percussion air tools need an oil built to travel with the air stream; use pneumatic tool and rock drill oil through the line oiler instead.
