Ok here is the deal, last night my daughter put diesel fuel in her XB gold, the car was driven 4.7 miles after that.

There was a little under a 1/4 tank of unleaded in the car when stoppd to get gas. She noticed after a few minutes that she was putting in diesel fuel. At that point she stopped putting in diesle fuel and drove home to tell me LOL. the drive home is 4.7 miles.

This happen in Jax., FL.

Anyone know someone that can help me with this.

 

Aren't the nozzles different? Like the diesel one won't fit in a regular one?

 

nope I went back to the station to get the miles from there to home last night and looked at the nozzels, it fit right in no difference in size at all

 

You need to drain the gas tank, and flush the fuel system, and hope your fuel pump, lines, and injectors didn't get ruined. The longer the Diesel sits in the fuel system the more likely the plastics/rubber in your fuel system would get damaged. Obviously until then, do not even start the car the motor.

 

you might have to replace the cat converter also...

 

diesle nozzles are a different siz then regular and running diesel is bad

 

Common mistake for newbs. I have never heard of it damaging fuel lines or the fuel system in any way. Just the motor won't detonate the fuel and the vehicle will run REALLY bad or not at all, depending on how much was added.

My opinion, if she only put a few gallons of diesel in there and there was already almost 1/4 tank, fill it up the rest of the way with the right fuel and see what happens. If the box runs really bad or won't run at all, drop the tank yourself.

It'll take a few hours but taking it to a dealer will cost you a few hundred to take it out/flush it. They have to get almost all the diesel out in order to warranty the work. A little residual diesel is no big deal.


Let us know how much roughly she put in gallons wise.


Pressing the big diesel button and picking up the big green handle gives it away... thats as far as gas stations go with preventing you from adding the wrong stuff. Nozzles are usually fitt-able.

 

thats the thing diesel fuel will cause damage to the fuel lines you have to drop the tank clean it out to get the contaminates from the diesel fuel out of the system and back flush it from the fuel lines hopefully it did not cause damage to your injectors either because those are pricey

 

I researched quite a bit to see if diesel will harm gas motor fuel lines, and the answer is no.

BUT, on diesel motors, if you put regular gas in them the seals they use are meant to work with the oily diesel to lube them so running regular gas will dry them up an ruin them.

Never heard of diesel ruining injectors and have searching I didn't come up with anything providing reason why it would.

Basically diesel needs compression, LOTS of compression (or heat) to ignite. Gas motors don't have the ability to ignite diesel properly, so the car will either run crappy... knock really bad, or just not run at all. I've seen mechanics chime in on the issue and they said just to drain the tank if the person filled up on diesel.. maybe change the fuel filter, but a gallon or two isn't an issue.

 

but the unfortunATE thing is the fuel filter is built into the actual fuel pumps on the xb so you would have to find out how to replace just the filter on in

 

Yea the internal pumps suck, but according to what I read it's pretty unlikely you will need to replace a fuel filter in this sort of situation. Guess we'll find out when the OP posts again.

 

This same situation happen to me when i had the xb.. i put diesel by mistake. i actually put like three gallons.. so what i did was fill it up with 93 unleaded and thats all.. it ran like crap until the tank was empty.. after all that nothin happen it just ran like crap the first tank when the diesel was in it..
