How To Use An Air Compressor
Set Up
Check the Oil
Most smaller air compressors these days won’t require oil to operate, but the bigger ones probably will. No matter the size, before you fire up your air compressor, check the manual to make sure your compressor uses oil, and where it goes.
Chances are good that if your compressor does need oil to function, you’ll find the dipstick near the bottom of one of the compressor’s ends. Pull it out, and just like with your car’s engine oil, check the oil level. Add more if it’s getting low.
In some cases, such as with our 80-Gallon NorthStar compressor, the manufacturer provides an easy to read window into your oil reservoir. Compressor oil can be found at most hardware, auto parts, and home improvement stores.

If the oil in your compressor’s oil window looks milky like this one, it’s time to change it out.
Fuel
When you’re using a gas-powered air compressor, try to use ethanol-free gasoline or something like TruFuel premix. It will help your compressor last longer. If you absolutely have to use regular gas, add an ethanol-specific fuel stabilizer like Stabil to it.
