Are Deves rings compatible with all types of cylinders, that is, the many different materials in cylinders?
Yes! Different automobile makers use different materials for their cylinders: aluminum, nikasil, alusil, etc. Our rings work well with all of them. We make rings for the European and domestic aftermarket, but we are best known in the European. In fact, we are the official aftermarket suppliers in the U.S. for Rolls Royce, and are very popular for Mercedes, BMW’s, and Porsches. It’s the Deves oil ring that looks very different from the OEM oil ring. Most manufacturers in the German market have a different type, usually a one, two, or three-piece oil ring. That’s why the question comes up. Mechanics are concerned that the expander in our oil ring will put too much pressure on the cylinder wall. If a mechanic is used to putting on a different type of oil ring, our rings do appear stiffer. That’s the way it should be. Once the ring is in the engine, the heat in the engine will loosen it up, and it adjusts to the cylinder. The secret is the Swedish steel.
