For the Fuel Gurus'

Well folks, this one is a good one. How do you seperate Gasoline and Diesel that have been mixed together in a gas tank?

 

[JohnnyO]

I don't think you can.

It depends if you are running a gasoline engine or a diesel( at least an older diesel) If it happens to be an older non electronic diesel, dump a quart of motor oil in too and run the mix out. any other case, Drain the tank completely and flush out your fuel rail when you refill by using the fitting for a fuel pressure gage with the gage removed. Then hope for the best when you start it up.

drain the take and refill best option if you ask me

seperate gas from diesel? cant be done, least not by any one of us anyways.

You know anyone with a very early john deere... like a model D or an early B or A? If so, Drain the mix and burn it in that. If not Drain the whole damn thing and discard in a responsible manner.

What vehicle is it in? And which is there more of?

I thought I'll ask. And you guys are right, it can't be seperated.

Here's the story:
My Dad is going to Minniasota to pick up a Honda Night Hawk 650. Two days before last night, he filled up his 91' Dodge 2500 Cummins with 87 Gasonline. And only caught it by the recipt on the night he was going to leave. And it was a full tank (30 gallons), about 2/3 Gasonline, 1/3 Diesel. So I spent the next 3hours with him to pump the fuel out as much as possible. Managed to get get about 23 gallons out. And filled the tank back up with Diesel.

The good news is that he is now in Minniasota. The truck ran fine and had no problems. Now what am I going to do with 23 gallons of Gasoline/Diesel mix fuel. Surely not run in the Ranger or my Kawasaki, or any other vehicle.

Maybe a lawn tractor or lawn mower? Or one kick ass bomb fire in the middle of the night.

sounds like the best bet to me, i hear you can run used motor oil through a diesel with out any consequences. maybe thin it out, like 5 gals per tank or so, with the rest being good clean diesel fuel?

Bond fire is the best choice....
if you try to run it in the lawn mower it won't run...period. My dad did this earlier this summer in his 285 JD rider...it simply quit running...try to run, pop and fart around...but did not run at all. drained the tank put an new filter on and fresh gas and ran great.

simulary in a gas powered car and truck...diesel fuel also eats at gaskets & seals in the fuel system. exspecially with cam driven fuel pumps...it eats the diaphram,(older vehicals anyway) then you get a crankcase full of fuel laiden oil. don't ask me HOW I know.

you could save it in 5gal containers for the coldest winter days and drop (1-3gal) per tank fuel of winter blend and burn it thru the diesel truck. just change the fuel filters in the spring when you gotten it all run thru.

my 2cents...hope it helps

So gaint bomb fire it is. Just gotta do it at a place thats legal and call the F.D. just to be safe for the burn.

I'll also still try the lawn mower thing, just for the hell of it. I got a mower engine thats dieing to blow.

Run it out.

Why not put a gallon or two in each time you fill the truck with diesel? I knew a guy who deliberately added 1 gal of gas to his Jetta diesel in the winter to make it easier to start.

Put a 1 or 2 gallon container of the mix in the truck & when you fill it up, add the can first.

A cheap ass briggs will run on Kero if it is good and hot. It (or any other engine) will not start on diesel/kero if it is cold. That's why old tractors have a small gasoline starting tank and a larger fuel tank.

it's mostly gasoline anyways, so just start the mower on gas, get it hot, and refuel with the crap. You could also use an unit propane torch to start on then open the needle valve as the engine warms up. I have done this before.

Send it back to the refinery ????

My cousin once, unknowingly put diesel in his Suzuki 160 4 wheeler, rode it over to my house about 1.5 miles away then he hit the kill switch and it kept running so he pulled off the spark plug wire and it just kept running. We didn't know what the hell was going on but he finally figured it out when he went to smell the "gas" and it was diesel. It eventually blew a hole through the piston about the size of a 1/2 dollar.

Perfect. All the more reason to kill that danm old Briggs mower engine. Sorry folks, when the mower is just about as old as yourself. The thing needs to die.

And also, thanks. I won't put it in any of my nicer mowers now.
