== == The tank has no drain, the diesel must be pumped out. Find the relay in the engine fuse box "circuit opening" and remove it, it has 4 prongs, use a wire to jump the recievers of the 2 large prongs in the box. go under the van by the front of the tank, remove the plastic splash guard, disconnect the 8mm fuel line and put it in a drain pan. turn the key on (do not start!)to activate the fuel pump. when it stops pumping put every thing back and add gas, it will be very hard to start until gas gets to the engine.

Diesel is not quite as dangerous for a gas engine as is gas in a Diesel. Still, it is still very unhealthy, so one must drain the fuel tank either through siphoning(not recommended) or by draining the Diesel fuel into an appropriate container throught the drainage outlet.

It depends how much petrol was put in. If it was a "full tank" draining the tank and the system would be advisable. If it was just a small amount, the mixture can be cut by adding more diesel with some motor oil mixed into it It is a common practice in times of diesel shortages to use motor oil with a small amount of gasoline added to it in place of diesel. You will have to use your own judgment as to how much diesel and/or oil to add.

It is possible that no damage will occur by accidentally filing a petrol motorcycle with diesel. The motorcycle make emit a lot of smoke as a result of doing this.

Toyota does not currently appear to be selling any light pickups with diesel engines in Mexico.
