TOM: Actually, what we worry about more is people putting stuff other than brake fluid in the brake fluid reservoir. If the viscosity of the fluid you use is too great, or too low it will cause the transmission to fail because the hydraulic properties and lubricity change. If load and surface speed remain constant, but elevated operating temperature causes viscosity to fall below that required to maintain a hydrodynamic film, boundary lubrication occurs; this creates creating the possibility of friction and adhesive wear. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear. DOT4 will perform a little better than DOT3 as … Bill, Quick answer, yes, you can mix. “You can choose an additive package from an additive supplier that has a zinc-type chemistry stabilized such that it can be mixed with a non-zinc fluid. Hydraulic fluid is 97% base oil and 3% anti-wear additives. Fluid Power means exactly what its name might lead you to believe; using fluid to create and transmit power.This makes Fluid Power a type of “power transmission”.
