Discussion in '6.7L 3rd Gen Cummins' started by Thor, Apr 17, 2009.
I'm not calling you a liar, but can you cite some proof of that?
Not true at all.
40 CFR Part 80 subpart I
A 15 parts per million (ppm) sulfur specification, known as Ultra Low Sulfur Diesel (ULSD), was phased in for highway diesel fuel from 2006-2010. Diesel engines equipped with advanced emission control devices (generally, 2007 and later model year engines and vehicles) must use highway ULSD
I'm tired of the government making up rules. I payed 40K its my truck and I'll run whatever fuel in it I want.
After looking into the CFR and other related sites, it also says you can run ULSD Kerosene and ULSD Biodiesel blends. I take that to mean that I can legally run WMO/WVO as long as the blend isn't made with anything other than ULSD.
For the most part, I take the CFR to pertain to folks who want to use regular diesel instead of ULSD, not for folks who are creating blends with ULSD.
kero blends and bio blend will not hurt the emissions sensors. Some where while I was researching this a few years ago I ran across the integrity of the emissions sensors as being a big issue. If what you blend will not hurt the emission sensors and can prove it, you might be ok.
This is absolutely UNTRUE! You should really do more research before you go spreading mis-information.
I hope to finally be buying one here very soon. Still looking for the perfect one without paying out the tail for it. So ya, we'll have to meet up.
I am not sure on the post 5.9 Cummins....
I do know on the 6.0+ PSD you really shouldn't use any alternate fuel, it can/will harm the injectors. Plus with the computer controls, very much non-diesel, like more that 15% can cause running issues, the combustion process is not putting off what the computer is expecting, and can throw it into a tizzy......
So, to answer your question, CAN you run Wxx in that era Cummins, probably. SHOULD you, no. I know in my case, with a 6.0 and the low percentage of waste that it could run safely, it would take a long time to pay for a set of injectors....... I have not had a chance to t-shoot mine, but I believe I may have caused an injector issue with a tank of questionable #2 from a pump...... would not take the chance with running waste anything in it.....
I'm running around 33.33/66.66 kero and wmo in my 2012 ram 6.7 deleted. Loves it and no smoke. The trick is to use a hydrometer and do your temp compensation and shoot for a .85 specific gravity. Centrifuge or filter to 1 micron. Add a nicknane 1 micron filter after the factory housing, it's made by pall and has beta ratio of 1000. Kero runs the best in the common rails due to there not being as much cylinder pressure but is not economical unless you can get it free like I can. It will run a 80/20 wmo/rug but fuel economy won't be as good. However egts are lower and actually quite safe using the rug due to the octane resistance to combustion under pressure and cooling in the process. Settle and filter to 1 micron before it gets in the vehicle and use 1 micron after the factory fuel filter. If you don't centrifuge make sure to filter for overnight. One pass is never enough
Also one part of the process that will make filters last longer if you do not have a centrifuge is (magic beads). The adsorption process they perform with the asphalts that develops in wmo makes the sludge stick to them. I have them in a 35g chemical spray tank and after 3 batches pull them and dip them in kerosene and put them back in. They are in 5gal. Paint strainers. Then disregard the kero that you clean them with because it's NASTY! Happy burning!
The problem the government seems to have with people running alternative fuels is the same thing the government is always complaining about, money. If your running alternative fuels your not paying road taxes.
The biggest issue I saw with running WMO is the potential of heavy metals making it past the filtering process. Something like zinc, or copper making it through your system (albeit in microscopic manner) could become deposited on your cylinder walls and have some pretty negative affects. My understanding is that a water/meth injection may help to mitigate this while helping to keep the injector coking down as well.
I've been running WVO in my Ford 7.3 for about 5 years now. Like others have said lots of filtering, down to 1 micron. I don't have a centrifuge.
The filtering down to 1 micron is very vague. As I described the beta ratio of [email protected] micron vs 100 which is standard 96% efficiency is very different ball games. And why I said multiple passes. As for coking and using water meth. That is only an issue with older non pilot injection as the combustion process is not nearly as efficient, and if you ran a 50/50 mix wmo/usld. Metal making it to rings? Hell every time you start your vehicle the cylinder that was intake or exhaust stroke has rusted cylinder walls and the rings just scrape that off and keep on chugging. I've pulled a cylinder head after 5 years of run time on wmo and still had the cross hatch on a 240000 mile motor. Not trying to burst anyone's bubbles just sharing my experience with the fellas.
I think the metal content would be more of an issue with where your getting your oil. Average mechanic shop is dealing with everybody out there, quality of the oil is going to be all over the place. Some people don't care as much about their vehicles as we do.
What centrifuge are you using? I've just been heat settling my WVO for a week or so and running through multiple filters down to 1 micron. I like the idea of the "magic beads"
I was told by my cpa that the rule is you have to pay road tax when you buy fuel not to drive on the roads. Right wrong or Indifferent I'm sticking to that.
