Federal-Mogul hybrid liner for cylinders reduces bore distortion and improves function in lighter, downsized engines; up to 40% reduction in oil consumption

Green Car Congress

As a result, engine oil consumption is reduced by up to 40%, according to Gian Maria Olivetti, Federal-Mogul’s vice president for Technology and Innovation, Powertrain. Conventional liners can allow water to seep down the joint between liner and casting, reaching the crankcase and contaminating the lubricating oil.
