Putting DEF (Diesel Exhaust Fluid) in a gasoline tank can cause significant damage to the engine and fuel system. DEF is designed for diesel engines to reduce emissions and is composed of urea and deionized water, which can lead to corrosion and clogging in gasoline engines. If DEF is mistakenly added, it is crucial to avoid starting the vehicle and have the tank drained and cleaned to prevent costly repairs.
Adding unleaded gasoline to the DEF (Diesel Exhaust Fluid) tank can cause significant damage to the vehicle's emissions system. DEF is a solution of urea and deionized water, and gasoline can contaminate it, leading to potential clogs and failures in the selective catalytic reduction (SCR) system. If this mistake occurs, it’s crucial to avoid starting the engine and to have the tank drained and cleaned by a professional mechanic to prevent costly repairs.
Get the system darined ASAP
In the gas tank...put one bottle to a full tank of gasoline.
Depends, usually drop the tank, clean with gasoline and reinstal. but might have to get a new one. It depends on what was put in the tank.
Diesel in a gasoline engine will not harm the engine other than that, depending on how much diesel you put in the tank, it will simply not run. It may clog the fuel filter or injectors but will do no other damage. Drain the tank and fill it up with gasoline if you put in over a couple of gallons.
A pint or less mixing with a full tank of gasoline, nothing will happen.
Don't know how much gasoline was put in or how much diesel was in the tank before gasoline was added but if you didn't run the engine after the gasoline was put in and you drained it, you should be okay.
They sell hotdogs for $1.50. Put that in your tank.
Only if you put diesel in gas tank.
Probably around 2900 gallons.

Considering that the fluid is an aqueous urea solution made with 32.5% high-purity urea and 67.5% deionized water it would not be a good idea to put it in the fuel tank of a gasoline engine. Nothing good would happen and lots of bad things will happen. Adding to this one... at no point does DEF ever go through the engine in a diesel, either. Exhaust first goes through the outlet into the Diesel Particulate Filter. Then it exits the DPF, and goes through a crossover pipe into the DEF doser. It is at this point that the DEF is sprayed into the exhaust, and, from there, it goes through the SCR catalyst then into the atmosphere. When we service or repair a DEF system, if you get any DEF on any tools with moving parts (such as ratchets), it must be washed off thoroughly right away, before it crystalizes, or else it will cause your tools to seize up. Now think about how many moving parts are in an engine.
