Data from fuel quality inspections conducted by the California Energy Commission at M85 dispensing stations indicated that significant contamination of M85 fuel may be arising from the station fuel dispensing equipment. Repeated testing revealed that high conductivity and high color occurred in the first liter of fuel drawn from a dispenser after not being used for more than 6 hours. As the dispenser hose was the most likely culprit for causing the dark color noted in the first liter of fuel, a study was conducted to ascertain the impact of dispenser hoses on M85 fuel quality. Three types of M85 dispenser hose were tested: the standard M85 dispenser hose (Goodyear Maxxim M85), and two experimental Goodyear hoses with nylon inner liners (Nylon Veneer 66 and Nylon Veneer 11).
