Unbelieveable---all the problems with the 6.0 that were caused by poor fuel quality, now fuel quality problems are being repaired, still someone wants to "lawyer up".

 

Is the sulfur what causes the black smoke because it seems that since the ULSD took over you see less and less sooting going on. The High Sulfur off road we use at work smkes like a mother but i always figured it was because offroad equipment doesnt have to meet as strict of EPA standards.

 

With that much smoke I would assume that the equipment is over-fueled to try to get more HP. The only farm equipment that smokes a lot is my old 67 which has 7000 hrs on her and original IP and injectors.

 

When the sulphur burned in my opinion, egr coking, turbo vane fouling, injector troubles happened. The fuel quality has always been a major issue with the 6.0. Most of the warranty claims have been in areas with notoriously poor fuel.

 

If my local fuel pumps use to have the 500ppm lable on them... but now they do not... does that mean they have made the conversion to ULSD 15ppm?

I was thinking that all diesel pumps had to have a sticker on them either as 500ppm or 15ppm so a user would know... but what if no sticker? Does no sticker mean it has already converted to 15ppm ULSD... which means old and new trucks alike can use?

By the way... ULSD 15ppm will NOT harm our diesels and if anything, may help those of us with '03 - '07's with EGR's... by keeping them cleaner. Even in older vehicles... the reduction in sulfur is made up with additives when refined and blended to meet an industry ASTM standard... so no need to worry.

Some have claimed in magazine reviews that a possible 1% reduction in fuel economy may be seen due to the new refining process that reduces the sulfur content... but there is nothing any of us can do... so get over it!!!

If any concerns... just use a name brand fuel additive for lubricity and know that you are trying your best to maintain your motor... but if my motor does developa problem.... I believe that it will not be fuel related due to ULSD... but something else that I failed to take care of.

 

Don W,

The system SHOULD be ok, but if you want the security of knowing you have enough lubricity for your trucks systems get the Stanadyne Lubricity formula. Cheap per tankfull to make you feel confident and it's OEM approved and ULSD formulated too. If you have any questions on it just call us.

I am not saying that the new fuel is bad but i put ULSD in my truck after 40,000k on LSD and Blew the turbo 2 miles down the road after fill up. hmm good thing it's under warranty. I have ran the ULSD ever since then with no problems so pretty mixed results there.

 

ULSD would not have blown your turbo... this is just coinsidence (sp)...

The only thing that ULSD may do is cause some leaking in the fuel pump seals due to slight shrinking and the difference in the aromatics of ULSD and LSD fuel.

 

well i am just telling you what the ford tech from deerborn who inspected my truck told me when they did a warranty inspection i think i am going to take his word. I'm not saying there is any thing wrong with the fuel.

 

Hey no sweat and glad to hear that it is covered under warrenty either way. I just find it hard to believe that they think it was the ULSD fuel.... because everything I have read on the internet and several truck and diesel magazines is that the ULSD fuel will only affect (or may affect) our fuel pump seals and possibly lubricity issues of the pump and/or injectors.... however... it is to be made to a strict ASTM standard to provide the proper lubricity.

This is why so many people use a fuel additive... to make sure....

I would be interested when you pick up your truck how they explain how and why ULSD fuel could or did ruin your turbo... becuase it runs off exhaust and ULSD actually should help it due to less soot/carbon being formed when burned????

 

I think that what's happening with the change to the ULSD fuel is the same that happened when we had to change from Old-Old diesel fuel to the Low Sulfer fuel - they've done their best to formulate out all of the potential problems that THEY ARE AWARE OF as a result of testing. But TESTING DOES NOT DUPLICATE REAL LIFE. So we will just have to be the "guinea pigs" and find out what real life results are - one example being shrinking o-rings.
Whether they knew that would be a problem or not before they released the ULSD doen't matter at this point. I don't think that the refiners had any choice whether to move ahead with the change-over or not. It was mandated my EPA - both Fed and State.
I believe that fuel lubricity is the most potentially damaging issue that we can only hope that the refiners have properly addressed for the pre-ULSD engines.
That's why I continue to use my trusty Redline stuff. It got me through the change-over to LSD with no problems.
