Abstract: Mass sensitive devices such as QCMs and SAWs coated with molecularly imprinted layers are suitable for chemical recognition and characterizing chemical changes in complex mixtures. This strategy makes it possible to e. g. monitor degradation processes in automotive engine oils. Polyurethanes were imprinted with either fresh or used oil to measure changes in the oil's chemical entirety as a result of chemical reactions taking place in the engine. After preliminary FT-IR measurements promising layers were applied on mass-sensitive devices. The mass effects observed depend on whether the layer was imprinted by fresh or deteriorated lubricant. By using a setup consisting of several different sensors (preferably two or three), external interferences such as changes in temperature, viscosity, etc. can be compensated. The sensor-signal depends on layer height thus proving a bulk effect in favor to surface adsorption. Mass effects can be related to degradation as they are depending of time in service. Additional parameters to determine are the water and fuel content of the lubricant, which is performed with affinitiy layers for water and imprints for fuel. Additionally the potential of inorganic polymers synthesized via the sol-gel process for engine oil sensing has been tested
