Selected research results are presented, including spectral analysis of noise emitted by an engine lubricated with rapeseed oil and mineral oil, in the context of the type of fuel used to power the engine. Wear measurements were carried out using a T-type tribological tester. Oil samples for measurements were taken at a specific mileage interval (1000 km). Before taking a sample, the vibration and noise spectrum generated by the engine operating under established load and rotational speed conditions were measured. The results of the rapeseed oil tests were compared with the results obtained in tests of the oil recommended by the vehicle manufacturer for the same operating conditions.The depletion of global crude oil resources and the desire to reduce environmental degradation caused by the emission of petroleum products and chemical compounds from their combustion process lead to an increase in interest in ecological fuels and environmentally friendly lubricants. Vegetable oils enjoy the greatest interest from scientific centers involved in the creation and testing of environmentally friendly lubricants as a raw material base. (…)
