I drive a lexus es350 07. I filled in diesel by mistake and before I could stop i filled in about 5gal. Now the car has 5gal diesel + 4 gal petrol. I drove 1mi after that to get it to my home and planning to tow the car to my local garage and have them flush the fuel system. But that can happen only tomorrow and I am worried about letting the car sit overnight with the diesel in it. Is there a way for me too siphon off the fuel from the tank ? Has anybody done this before on a Lexus ?
