Evaluation of Potential Engine Oils for Use in Administrative Vehicles Operating on M85 Methanol Fuel

摘要

Six lubricants, comprised of various lubricant formulations, were evaluated to determine which potential engine oil would provide more wear and/or corrosion protection for administrative-type vehicle engines operating on M85 methanol fuel. The six lubricants were first evaluated using a modified ASTM V-D cyclic test procedure. The three best oils were then evaluated in a second test series using steady-state/cold test conditions. These three oils provided the same order of protection from wear and corrosion in the steady-state/cold test conditions as they provided using the cyclic test conditions. All three lubricants coded AL-15427-L, AL-16155-L, and AL-15610-L are recommended for use in administrative-type vehicle engines when operating on M85 methanol fuel.
