Put diesel in my Taco

Don't do that. If only the tank is contaminated just drop the tank, clean the tank and the pump. Don't run the diesel through the lines as they will get contaminated. Assuming you still didn't turn the ignition on and try to start the truck.

 

What happens if you put E85 in a turd gen? Does the ECU have mapping for that?

 

a disaster of biblical proportions....Old Testament, real wrath-of-God stuff... fire and brimstone coming down from the skies. Rivers and seas boiling. Forty years of darkness. Earthquakes, volcanoes…The dead rising from the grave. Human sacrifice, dogs and cats living together – mass hysteria.

 

I don't want to try. Toyota says not to use anything more the E15.
