Can RVS products be used in ethanol engines?

Yes, they can! The active substance in RVS Technology products does not react with ethanol in any way.
Furthermore, using RVS in ethanol engines is even more recommended than in gasoline engines as the lubricating properties of ethanol are worse than those of gasoline, which, in turn, makes wearing processes more intensive. When entering lubricants, ethanol reduces their properties more than gasoline does, and, with triboceramic surface, the extra wear can be prevented.
