Where do you put oil in vespa 1/4 hp air compressor and what kind of oil to put?

SOURCE: I have a 2 hp

30 weight Non Detergent Air Compressor Oil is what you should use, although any 30W Non-Detergent Oil would work. Quantity wouldn't be much since it's only 2 HP. As far as the breather plug/oil cap, you caould try FD & Sons Hardware @ 866-612-5454. They showed as being a Mincraft Distributor.

Hi. You need compressor oil. But if you can't find any try using motor oil. 5w 20 will do fine.
Good luck.

Hi, I have 1/2hp Vespa Air compressor. It is running okay but it does not have air pressure. The gauge pressure is not moving anymore. What seems to be the problem? Help is greatly appreciated. - el
