I accidentally put E-85 gas about 1/2 tank in my 2013 ES-350. The check engine light came on and Trac off light.What do I do? Can I siphon out the gas or is there an anti-theft in the tank? How do I do it? Can I top the tank off with regular gas? or will that harm the fuel pump, gas lines, etc. I'm so embarrased !!!!
