As emission regulations tighten across various regions of the world there is a growing trend in the use of alternative fuels such as Ethanol being blended with gasoline. A notable case of Ethanol usage is found in South America with the widespread use of E100, which has no gasoline content and can often contain up to 10% water. Engine oil contamination by fuel is of major concern and under certain conditions can have negative effects on the durability of turbocharger components which come into contact with contaminated oil, particularly sliding bearings, but also compressor stage through crankcase ventilation system fed gas. The manner in which this effect takes hold can cause a decrease in the lubrication properties and increase in corrosiveness of the engine oil.
