For older Roots Universal RAI blowers that utilize grease in the drive end, you may be able to use Shell Gadus S2 U1000. One tube contains 14.1 ounces of grease.

Shell Gadus S2 U1000 2 grease is an inexpensive clay-based lubricant. It is multipurpose but cannot be used in gas applications. Several years ago Shell Gadus grease replaced Shell Darina EP 2 grease which is now obsolete. Features include: non-melting; excellent resistance to water washout; good load carrying capability; good resistance to rust and corrosion.

Starting in 2016, Roots began using a synthetic grease in their blowers. Click here to learn more about which type of grease to use in your blower. Different types of grease cannot be mixed because they will separate and no longer provide proper lubrication for your blower.
