Preliminary Compatibility Assessment of Metallic Dispenser Materials for Service in Ethanol Fuel Blends

The compatibility of selected metals representative of those commonly used in dispensing
systems was evaluated in an aggressive E20 formulation (CE20a) and in synthetic gasoline
(Reference Fuel C) in identical testing to facilitate comparison of results. The testing was
performed at modestly elevated temperature (nominally 60°C) and with constant fluid flow in an
effort to accelerate potential interactions in the screening test.
Based on weight change, the general corrosion of all individual coupons exposed in the vapor
phase above Reference Fuel C and CE20a as well as all coupons immersed in Reference Fuel C
was essentially nil (
