Cleaning your paintball marker and keeping it lubed up are vital to keeping them going on the field. Some markers use oil, some use grease, some use a very specific type of grease, so what kind of lube do you use on your paintball gun? You will want to refer to the owners manual of your marker for a definitive answer to what you need to use, but commonly the following is what is generally correct.
Paintball guns such as Tippmann, Azodin, and Spyder typically will use oil on the bolt / hammer but may use grease (Dow 33) in the regulator and on the valve. Most spool valve markers, or closed bolt design markers will use grease (Dow 33) in all areas of the marker, bolt, regulator, ect. Open bolt paintball guns, like the Planet Eclipse LV1.6 will use oil on the moving parts such as the rammer and bolt, but will use grease (Dow 33) in the regulator and on the valve. Some specialty or older markers may utilize a thicker grease but it is very rare. For example, a lot of Bob Long guns use Dow 55 instead of the more common Dow 33 Which is the industry standard for grease.
There are multiple different options available for grease and oil, a part of choosing which to use will be personal preference, however most manufacturers recommend using the ones provided with the marker. All Dye, Luxe, Shocker, and Planet Eclipse markers utilize Dow 33. Some Greases are designed to be lighter weight, allowing your marker to cycle with less resistance.
