Some lubricants are incompatible because of differences in additive chemistry that lead to undesirable chemical reactions. If these oils are mixed, insoluble material may form and then deposit onto sensitive machine surfaces. For a hydraulic fluid, this could lead to lubricant starvation, valve failure or increased wear.
A second form of lubricant incompatibility is more insidious because no visible changes occur when the products are mixed. The problem appears only after the mixture is used in a piece of equipment that consequently fails or loses performance. For example, hydraulic/tractor fluid that is contaminated by motor oil can lead to brake chatter and failure in farm equipment. Optimum performance requires carefully balanced frictional and antiwear properties in the finished product that are upset when the lubricants are mixed.
Some incompatible lubricant mixtures may also affect synthetic rubber seals. Lubricants are formulated to be neutral to seals or cause them to swell slightly. Too much seal swell, seal shrinkage or chemical deterioration may occur with some combinations of lubricants. Engine oils formulated with certain types of dispersants attack fluorocarbon seals. Lubricants contaminated by products containing ester base stocks may swell seals unacceptably. EP gear oils are known to deteriorate silicone seals.
Lubricant incompatibility is a chemistry problem. It has nothing to do with the manufacturers of the oil; two oils made by the same manufacturer may be incompatible. The most common cause of lubricant incompatibility that results in the formation of harmful solids is the reaction of an acidic component in one oil with a basic component in another. The reaction is accelerated by water and heat.
Oils containing acidic rust inhibitors are incompatible with oils containing basic rust inhibitors. When the two oils are mixed, especially when some water is present, a solid forms in the oil that reacts further with the oil to form a grease-like insoluble substance. This can clog filters, form deposits that interfere with lubrication and interfere with demulsibility (water-oil separation).
One way to look at potential lubricant incompatibility is to classify lubricants as acidic or basic. Table 2 is not meant to be totally inclusive and some exceptions may occur. Different lubricant manufacturers may use different additive chemistries to accomplish the same function, so caution is warranted. Check with your manufacturer to be sure.
Lubricants that require good demulsibility (water separation) should never be mixed with lubricants that contain dispersants or high concentrations of detergents. Small amounts of oil with good emulsion characteristics will destroy the water shedding properties of a highly demulsible lubricant. Rarely can the demulsibility be restored with additive supplements.
Lubricants formulated with non-zinc antiwear and antioxidant additives such as railroad engine oils and ashless or low-ash gas engine oils will cause engine damage if they are contaminated with lubricants containing zinc additives.
