An engine control system comprises a fuel composition module, a comparison module, and a memory module. The fuel composition module determines a fuel composition and an amount of undesired fuel in the fuel composition. The comparison module compares the amount of undesired fuel to a misfueling threshold. The memory module records a misfueling event based on the comparison.

1. An engine control system comprising: a fuel composition module that determines a fuel composition and an amount of undesired fuel in said fuel composition;a comparison module that compares said amount of undesired fuel to a misfueling threshold; anda memory module that records a misfueling event in response to said amount of undesired fuel being greater than or equal to said misfueling threshold. 2. The engine control system of claim 1 wherein said memory module records said misfueling event by storing at least one of said amount of undesired fuel, a date, a time of day, and a location. 3. The engine control system of claim 1 further comprising a driver information center that provides at least one of a visual and audio alert based on said comparison. 4. The engine control system of claim 3 wherein said driver information center provides said at least one of a visual and audio alert when said amount of undesired fuel is greater than said misfueling threshold. 5. The engine control system of claim 4 wherein said at least one of a visual and audio alert indicates that said amount of undesired fuel is greater than said misfueling threshold. 6. The engine control system of claim 1 further comprising a diagnostic module that communicates with said memory module and receives said recording. 7. The engine control system of claim 6 wherein said diagnostic module displays said recording. 8. The engine control system of claim 1 wherein said memory module records said misfueling event by storing said amount of undesired fuel and at least one of a date, a time of day, and a location of said misfueling event. 9. A misfueling notification method comprising: determining a fuel composition;determining an amount of undesired fuel in said fuel composition;comparing said amount of undesired fuel to a misfueling threshold; andrecording a misfueling event in non-volatile memory in response to said amount of undesired fuel being greater than or equal to said misfueling threshold. 10. The misfueling notification method of claim 9 further comprising recording said misfueling event by storing at least one of said amount of undesired fuel, a date, a time of day, and a location. 11. The misfueling notification method of claim 9 further comprising providing at least one of a visual and audio alert based on said comparison. 12. The misfueling notification method of claim 11 further comprising providing said at least one of a visual and audio alert when said amount of undesired fuel is greater than said misfueling threshold. 13. The misfueling notification method of claim 12 wherein said at least one of a visual and audio alert indicates that said amount of undesired fuel is greater than said misfueling threshold. 14. The misfueling notification method of claim 9 further comprising communicating with a diagnostic module that receives said recording. 15. The misfueling notification method of claim 14 further comprising displaying said recording with said diagnostic module. 16. The misfueling notification method of claim 9 further comprising recording said misfueling event by storing said amount of undesired fuel and at least one of a date, a time of day, and a location of said misfueling event.
