Keep in mind that gasoline has a shelf life of only about six months while diesel has a shelf life of a few years. I have no idea what the shelf life of a mixture would be, so I would not keep it much longer than six months.

The problem is that the lubricity spec. of ultra low sulphur diesel in the US is only just high enough to lubricate the new generation of very high pressure fuel pumps, and ANY gasoline present reduces the lubricity below the acceptable level.
No Worries in my case. I have a 2000 Jetta Diesel with 216,000 miles. runs like new.

Re: Unleaded Petrol put in Diesel Tank

Gary-
"New diesel fuel suc@s big time. If it ain't broke don't fix it."
That is the precise problem, the entire diesel "system" was broken and needs to be fixed. Traditional diesel engines and diesel fuel dump a lot of particulates in the exhaust, enough so that the US basically banned diesel cars for 20? years because the particulates do cause enough health problems (beginning with asthma) so that we can say the "ain't broke" system was and is killing people. Slowly and painfully killing people.
The EU was ignoring this. Supposedly the newer fuels will burn cleaner, and the new diesel technologies (using a urea tank for after-burning the exhaust) are clean enough to make both the EU and US happier.
And those of us who can always smell the diesel stink from a running diesel, will gladly tell you that traditional diesel engines run dirty, no matter how you slice it. Anything that stinks and makes people nauseous during normal operation, ain't "ain't broke".

Pretty much every invention from the industrial revolution forward kills people. Never the less, the planet has 7 billion racing to 8, so the pollution does not seem to derail us.

"Pretty much every invention from the industrial revolution forward kills people."
So perhaps we should all become Bhuddists? "Life is suffering, then you die."

And ignore all the problems because suffering is normal, death is normal, and...no, wait, I'm confused, why then do Bhuddists bother feeding the poor and priests if that only prolongs their suffering?

If the gas concentration is high it will eat up all the seals in the fuel system. It happened to me.

Re: Unleaded Petrol put in Diesel Tank

I would use one of the vacuum engine oil removal pumps to remove the petrol. The other option is siphon.
No electricity and therefore less chance of a spark and associated boom.

Perhaps you shouldn't quote what you know nothing about?

As if you were hiding in the bushes and heard my conversation with the Bhudda himself? Or perhaps, philosophy is no longer open to interpretation and variation?

Re: Unleaded Petrol put in Diesel Tank

Hmmm.. from gasoline in a diesel tank to philosophical debate on eastern religion?
How do you spell "Thread Drift?"
As already posted, remove all the gasoline from the tank, using either a gasoline rated electric pump, or a hand pump, add a gallon or so of fresh diesel, then remove the diesel, which will have mixed with the residual gasoline still in your tank, and THEN fill with fresh diesel. If you use an electric pump, (Fillrite, Gasboy) you can pump the single gallon of diesel into the tank with enough force to "stir up" some sediment and/or water, and clean your tank some, while getting rid of the gas. Good luck.

Re: Unleaded Petrol put in Diesel Tank

Good on ya, Pearcey... I believe if you had a small residual of gas (petrol) in the tank and it was properly mixed with your diesel, you wouldn't do much damage. I say this from experience driving Kenworths in the NWT one winter where we never shut down our rig. If we did, a sure fire (excuse the pun) way to get her going if we didn't have any ether was to mix in a shot of gasoline into the diesel tank, mix it up with a stick through the filler hole and hit the starter. There were probably a few accidents but we either didn't here about them across the bar or they didn't happen. With the newer diesels, it might be problematic with seal deterioration and such but with the old bangers there wasn't much to worry about. Sure don't miss the -30 below days! Phil
