By mistake 5 gals of E85 fuel was added to the tank of my 1997 Ford Explorer. The tank was half full at the time and 5 miles after the E85 addition the tank was topped off (Full) with regular gas. 25 miles later the check engine light came on. The scaner code read 1 problem P0136. The computer was reset and the check engine light has stayed off. Are there any other things I should be doing to avoid furture problems? Ie drain the tank, add some sort of aditive to counter the E85
The engine runs fine but I am hesitant to run it.
