E85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E85
fuel, the engine will have some or all of these symptoms:
•
operate in a lean mode
•
OBD II “Malfunction Indicator Light” on
•
poor engine performance
•
poor cold start and cold driveability
•
increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E85 perform the following:
•
drain the fuel tank (see your authorized dealer)
•
change the engine oil and oil filter
•
disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasoline blended with MMT offers no performance
advantage beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT have been
shown to reduce spark plug life and reduce emission
system performance in some vehicles. The manufacturer
recommends using gasoline without MMT. Since the
MMT content of gasoline may not be indicated on the
pump, you should ask your gasoline retailer whether or
not their gasoline contains MMT.
