Treating Motor Oils with By-pass Filters in Automotive Engines

The expediency of incorporating additional by-pass superfine-treatment filters (STF) in the lubrication systems of automotive engines remains the subject of research and discussion. Specialists express differences, which frequently contradict opinions concerning the effectiveness of these filters under modern conditions. Increasingly rigid standards for the emission of toxic substances by vehicles are gradually being introduced through ecological legislation. A reduction in harmful emissions is being achieved by joint efforts of automotive manufacturers and oil refiners.
