SITUATION

Fuel blends containing a high percentage of alcohol (10% and above), mainly ethanol, are becoming more commercially available. Usage of E85 or

any other high alcohol content blend (e.g., E30) in MINI vehicles will cause various drivability complaints (cold start problems, stalling, reduced

performance, poor fuel economy, etc.); may cause excessive emissions; and may cause irreversible damage to engine, emission control and fuel

delivery systems due to incompatibility of materials with alcohols. Refer to SI M13 01 06 Alcohol Fuel Blends in MINI Vehicles for complete

details.

In order to correctly diagnose various drivability complaints caused by fuel blends with a high level of ethanol content, MINI is providing you with

an electronic fuel composition tester.

PROCEDURE

Safety Precautions:

^ Gasoline is highly flammable; observe normal precautions for working with flammable liquids. Perform all tests away from any source of ignition.

A class B fire extinguisher must be available.

^ Wear protective eye protection with side shields and Nitrile rubber gloves for handling the tester.

^ Please adhere to any applicable OSHA regulations when handling gasoline.

^ Dispose of the mixture according to local, state and federal regulations.

Refer to the attached procedure for testing the fuel composition in gasoline.

WARRANTY INFORMATION

Component damage, malfunctions, or any drivability problems verified to be caused by the use of fuels containing more than 10% ethanol (or other

oxygenates with more than 2.8% oxygen by weight) will not be covered under MINI warranties as this is not considered a defect in materials or

workmanship. Always document the results found on the vehicle repair order whenever performing this test.
