ROYAL PURPLE SYNTHETIC COMP OIL 1 Quart

I have used Royal Purple motor oil, gear oil, and compressor oil for years I use it for my compressor that supplies air to my pcp airguns. The compressor oil separates the water from the oil fast and it’s lubricity is well known. This oil is hard to beat. I use it in my Yong Cheng High Pressure DIGITAL compressor to fill my pcp guns and supply tanks. DrDave. Utah, USA

one of the best compressor lubricant oils in the industry. fully synthetic oil will last longer than regular oil. keeps my hpa compressor running silky smooth.

Great stuff period

The oil in my 2-stage compressor (inherited) was probably nearly 40 years old. The machine had not been used much but was running hotter than I was comfortable with. Drained the oil which was insufficient in volume and somewhat contaminated. Given that 40 grade compressor oil is unobtainium in the US, I figured better get a good brand of 30 grade. Runs quieter and much cooler! Very happy with this.

The pump threads that would screw on the bottle are not even close so the pump does not tighten down; it flops all over the place and if you are clumsy like me you will get oil all over the place. Second thing aboiut the pump; the suction tube is 1.5IN too short to reach the bottom of the bottle so the last 1/4 quart cant be suctioned up into the pump. This totally defeats the purpose of the pump all together. Just buy the oil and forgo the pump option for the additional 5.99. Pump IS NOT worth it at all.
