DON'T TRY TO START IT. have the tank drained and reinstall gas. If just a couple of gallons were put in, don't worry about it. It will run with a little diesel fuel in the gas but may smoke a bit. First, drain the fuel tank. Remove all diesel fuel from the tank before attempting to start the engine again. Next, determine if the vehicle has a recirculating fuel system. Many of the injected engines have a pressurized fuel system that recirculates back to the tank. If that is the case with your vehicle, fill the tank with the preferred fuel, turn the ignition switch on for five seconds, turn it off again, and repeat the process a few times to circulate diesel fuel out of the line. A small amount of diesel fuel that mixes with your conventional fuel will not harm the engine. If the engine will not start you may need to use a small amount of ether based starting fluid to get the remaining diesel fuel out of the injectors. Once the vehicle starts again it should run properly after you have worked the residual concentrated diesel fuel out of the line. If you determine that your vehicle does not have a recirculating fuel system, open the fuel line near the injectors, place a flexible tube of some kind over the fuel line and drain enough fuel to allow all of the diesel fuel to be removed. Get as much of the concentrated diesel fuel out of the line as you possibly can before attempting to start the engine. Short bursts of starting fluid should keep the engine running while you burn out any remaining diesel fuel.

Can you still drive if you accidentally put a large amount of diesel in your petrol car?

If the engine will run you could drive it, but I would advise against it. The diesel may damage the O2 sensors and catalytic converter. Drain the tank and then fill it up with fresh gasoline. No real damage will be done with the small amount of diesel left.

What if you accidentally put diesel fuel in your car instead of petrol?

Depending on the mix (how much petrol vs how much diesel), the car will either not go at all, or may go but feel jerky. It is obviously not recommended to put ANY diesel in a petrol engine, simply because of the way a petrol engine works vs how a diesel engine works. In a petrol engine, the fuel is made to combust only with a spark, and therefore requires a much higher pressure for combustion to take place. The higher the octane of the fuel, the more pressure is needed for the fuel to combust. A diesel engine works in the opposite way, where it needs less pressure and no spark to combust. If you have accidentally put diesel in a petrol engine, don't drive the car. Drain the fuel. You may have to replace to fuel filter and the spark pugs Comment: To clarify the above logic. CAUTION!! Diesel engines have compression ratios of 15:1 or more so that PRESSURE (not spark) ignites the fuel. Petrol engines use SPARK to ignite the fuel. The high octane rating of petrol is so that it does not PRE-IGNITE (pink) under pressure. Raise the compression ratio and you need a higher octane rating, which is why some petrolheads use Avgas (130 octane) on their high performance engines. Diesel engines need HIGH pressure to operate, petrol engines can use LOWER pressure to work, but need higher octane rated fuel if the pressure rises.

Can you put diesel in to petrol engine?

Not if you want it to run.

What do you do if you accidentally put petro in a diesel car?

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.

What happens if you put diesel oil in a petrol car?

Putting diesel into a car made to take regular gas is a very bad idea. Diesel can really mess up a car's fuel system, resulting in the need for expensive repairs.
