hey cowboy, you got some numbers wrong, its not 15%, its 15 parts per million (PPM)
one reason (out of the many) is because they refine so much of the sulfur out of it. Now, if you have an older truck with an injection pump, even a 7.3 or 6.0, that sulfur is used to lubricate the fuel system, which means you need to put sulfur(through additives, we use one by stanadyne) back in it.

 

A little gas won't hurt anything but a commonrail. Here in minnesota, when it gets sub-zero (which is often), I toss in two gallons of gas in a full tank of #2. This seems to work down to thirty below. First, it's cheaper than blend, #1, or additives. Secondly, it seems to work better than power service for gelling that occurs in the filter. I have done this for years in semi-tractors, ag tractors, and my 12v pickup. Nothing has failed in well over a decade

 

I don't know what to say except your never filling my truck up.

 

If you ever do this before you turn the key on to engage the electric fuel pump climb under the truck loosen the filler tube hose cut the nearest water hose in two an siphon everything out of tank and knock on the bottom of the tank till you hear it have a hollow sound and refill with diesel and unhook the line from tank to filter and turn key on to let pump run a few times off and on to let fuel drain into a diesel can to make sure no raw gas will go into your filter or spend thousands of dollars later. Hope this helped.

 

You guys are over reacting to a little bit of gas mixed in your diesel. Most of this is due to mis-information and not knowing about how a diesel engine operates. A few of us do this on purpose to keep from freezing. And if you use waste motor oil as fuel then most cut this with gas anyways. You guys would rather spend hundreds of dollars on towing, draining tanks, wasting perfectly good fuel, ect. I say run it and don't look back!

In the end you will do as you wish. You can waste a lot of hard earned money if you so desire!

 

You seem to be out numbered on this issue.

11 years as a mechanic, certified by my province, and the government, I know what is supposed to put in my tank, and how an engine works.

A proper winter anti-gel product will do the same thing, and not reduce the lubricating factors of the diesel fuel.

Hundreds? It doesn't cost hundreds of dollars to drain a tank and throw a jerry can in. If you don't put gas in diesel in the first place, you don't have to spend any money except for the fuel you put in. Improper lubrication in the precision fit injection system can cost thousands.



I will do a I wish, you do as you wish. I bet in the end I spend a lot less then those that run gas in their diesel.

 

A little gas is ok to prevent gelling but not a full tank or half tank IT WILL LOCK UP!! Guaranteed

 

Someone who don't know crap about a diesel or anything mechanical should probably call for a tow truck, take it to have a mechanic fix it. Most of you guys saying don't do it can't even spell wrench let alone have been around old tractors, semis, generators, ect. I have 22 yrs of real world mechanical knowledge, a degree in diesel mechanics, a degree in agricultural diesel, a degree in alternative fuels and ASE certified in 5 areas.

Ideal situation no don't put it in. If it gets put it in by mistake then make the best of things and add some motor oil and run it. It cost nothing! It requires almost no effort! I will spend nothing in the long run!

As I said before those of us who run a 2 tank system for burning waste motor oil, trans fluid, ect, we use about a 10%-30% blend of oil an RUG (regular unleaded gasoline). You can use diesel but it cost more and doesn't dilute as well.

 

There's always room for more then one opinion and for all of them to be right. The idea here is to give the best info you can and let the readers decide for themselves how they feel about it. Nobody has to be proven right or wrong.

 

I'd have to agree UB!
