Actually Cummins just approved the use of B20 in our trucks a few months back. I actually got an e-mail from them. All the other diesel manufactures say 'No' to bio or the highest bio they'll let you run is B5.:dm:

ya it says on the Cummins site I believe that they like up to B20

Where ya been Michael

Yes Cummins has approved the use of 20% Bio with extra filtering for water. Dodge only allows 5% Bio when it comes to those who have a warranty. Below is from Cummins on Bio fuel.

----------------------------------------------------------------------------------

A maximum blend of 5% biodiesel (B5) is acceptable as long as the biodiesel mixture
meets ASTM specification D-975, D-975 - grade S-15, and ASTM D6751. A biodiesel fuel blend that is higher than 5% is not acceptable without additional fuel processing because these higher percentage biodiesel blends contain excess amounts of moisture which exceed the water stripping capability of the on-engine final fuel filter. Should a higher percentage biodiesel fuels be used an auxiliary water stripping filter will be required.

A maximum blend of 20% biodiesel (B20) can be used by government, military, and
commercial fleets who equip their vehicle(s) with an optional water separator, and adhere
to the guidelines in the Department of Defense specification A-A-59693 (in addition to:
ASTM specification D-975, D-975 - grade S-15 and ASTM D6751)

Yeah but a member on another forum told me that Cummins might allow up to a B20 fuels but Dodge will only allow up to B2 for warranty coverage... Cummins has nothing to do with warranty repairs its solely Dodges problem... So you MUST go with Dodge's guidelines for warranty coverage...

The only reason I know this one I got a few phone calls from guys make there own BIO. B100 of all things and done some fuel system damage and ended up losing his warranty and pay for the repairs... He was told the maximum was B2 allowable by Dodge's Standards...:w2:

Is an Airdog water sperator considered a good enough filtration unit to remove the moisture of B20? Reason I ask is cause I did just install an Aidog system on my truck and I know several local fuel stations are only offering Biodiesel now. I just want to make sure IF I end up purchasing Biodiesel that I wont ruin anything.

I would contact PureFlow Tech. and ask them if it can handle it...

Performance Manufactures

The only things you should really have to worry about is the filter clogging up faster and having to drain water more often. I'll shoot Charlie a PM and get him to post info here.

There really shouldn't be any more water in Biodiesel than there is in petroldiesel. If there is water in the fuel, you need to have a talk with the producer, because he should be drying the fuel better.

We'll wait for Charlie to give us the authoritative answer, but I don't think that the water separator removes water that is "atomized" or whatever they call it into the fuel. It only removes free moisture.

Get a glass of biodiesel if you see the water droplets, that is what will be removed by the water separator, the water you don't see is what is dissolved or atomized into the fuel.

I have never tried this, but I was told that if you take one of your wife's favorite frying pans and pour some bio-diesel in the the pan. Put it on the stove and raise the temparture to over 212degrees... if there is water in biodiesel it will sizzle at the boiling point of water.

The AirDog has no trouble with biodiesel. The wire screen prefilter/water separator catchs the large parrticlates and the Stratapore filter handles the rest. The veggie oil conversion people, Fossil Free Fuels, Grease Car, etc., use our Raptor fuel pumps with their conversions. No problems, just a real good pump!

Im bringing this one out of the attic, its an excellent source of information for new users, and I am wanting to see some updates on any Duramaxes and Powerstrokes that have been running 2 stroke oil in their trucks..


:pca1:

Well I can tell you I work over at TDG.com as a moderator and so far the Ford crowd is having no issues. Chevy on the other hand is quiet... I need to check in on the boys...

Buy I'm been using 2 cycle oil in the fire truck here for the last 2 years without any ill effect to the trucks performance. As a matter of fact it helped the 6.5L Chevy fast attack I drive considerable. Used to be rather loud in the injectors now it really quiet...

http://i143.photobucket.com/albums/r...t/DSCF1074.jpg

If I'm using in a emergency vehicle(s) you know I got good faith that its not going to harm anything... And it hasn't... :U:

I've been using 2 stroke oil in my 04.5, with the kitty, for almost 3 years now with no ill effects at all. In fact, I just got back from a trip over Thanksgiving to ND and essentially averaged 20mpg for the 2 tanks of fuel that were used essentially for highway driving!!! Most of the highway driving was running 70-75mph also!! In my 3rd gen, I use 1/2oz per 1gallong of diesel. Mikes the brains, I'm just a cheerleader!!:U:

When i picked my new truck up (same as yours) i was running down some back roads at about 50-55 (following school bus) and the computer was reading 21-22mpg (no oil added) we were headed to the gas station before we jumped on the highway.. Filled up added a qt of oil to a full tank, running down the highway 70-75 computer was showing 15-15.5 but if i kicked it up to about 80, it would drop to about 14.5 after awhile, and then i tried kicking it down to 60-65, and it went up to about 16-17. When i got home, i filled it up computer was reading like 15.7 and i did the math and it got 15.6!! so the comp is somewhat accurate, i just dont understand how you guys are getting that kind of mileage running 75..
I am getting a AFE CAI for xmas and as soon as i get it inspected the kitty is going buh bye. maybe that will help?? And as far as running it hard, i shift about between 1500-1700 rpms and arent trying to set time records shifting so.. Any help? I think i might run the rest of the fuel out of it that has oil added and then run a tank without it and see what happens.... Also as soon as i got home, i changed the oil and fuel filter...:argh::argh::argh:

Take notice everyone of them has a truck that has a body lift and oversized tire on it... That right there raises a RED flag in my head. More than likely most of then have odometer and speedometer that are out of calibration and get incorrect mile numbers...

Like myself I found out with my stock speedomoeter, my ScanGauge II, and Garmin GPS I found out I'm off by exactly 0.5 MPH so by a tank of fuel I could be off as much as 20 Miles. Which in turn is about 0.2 MPG offset between the SG II and hand calculation of the speedo.

But I can pull 23.7 rather easy in the summer time... (But at 55-60 MPH)
http://i143.photobucket.com/albums/r...T/DSCF2968.jpg

You can see from my signature what I have on my truck. Stock sized tires, no lift, and I "work" my truck. It isn't too often that my truck doesn't have a trailer on it!! On my ND trip, the wind was not behind me coming and going either. It was at my side essentially the whole way....out of the SW!! The tank of fuel that I didn't mention in my post above was the tank that was essentially just running from hunting spot to hunting spot. So it had lots of cold starts and extended high idling.....especially first thing in the AM!! That tank was under 17mpg if I remember right!!

With the onset of winterizied diesel here in Idaho and the lower of BTU's of the fuel from 55 Cetane fuels I've dropped from 21-23 MPG to just around 15-17 MPG. I've just completed running 2 tanks for test purpose without 2 Cycle oil and no change to the MPG at all. Still floating around 16 MPG.

But to give yo guys a clue...
http://i143.photobucket.com/albums/r...etane-btu3.jpg

Yes the light green is winterized fuel and dark green is summer fuel. But for point of reference gasoline is a 125K BTU's so I know that high cetane fuel don't mean better performance actual the reverse... But now notice lower cetane fuels is much highier in BTU content.

So when summer returns we all rejoice in the increase in MPG's... Maybe because the cetane is reduced again to around 40 cetane...

I have an '06 with a bad injector rattle. Would the 2-stroke oil help it or quiet it down any?? Any help would be great.

Yes it would help be what I found out about 3rd Gen fuel systems is that... Yes it would stop the rattling noise for a short time... But from what I'm learning on 3rd Gen injectors is that they soon fail anyways. This is because the damage is already done. But it might extend the time till it fails...

Here is a interesting PDF I got today... It a huge learning curve...

Key there is fuel lubricity! :w2:

http://i143.photobucket.com/albums/r...20oil/hfrr.jpg

So the first time that you add the 2 stroke oil for example my truck has a 35 gallon tank would I add 35 onces of oil to it when its full and then when I filled up again for example 14 gallons I would add 14 onces of oil correct:humm:. Sorry if this is a confusing question Im new to the 2 stroke oil thing. Thanks for any advice

I add 16oz when I feel up my tank.

How is this John Deere premium diesel fuel conditioner? I use it in my 98 6.5 surburban...but it's expensive as hell.. and I don't know if it does any good, thinking on 2 cycle oil now...great info on here guys.

I've been adding 32oz to about 32 gallons every time

i just recently started adding the 2 stroke to my 01 cummins. it definatley quietes it down and seems to run smoother. i have ran powerservice for a while before that and am more pleased with the 2 stroke. :U:

I used the Wally mart brand 2cycle oil on my 02 F350 Powerstroke. I did it for about 3 months and I developed leaks in all of my High Pressure oil pump O rings.:argh: The 7.3's are notorious for delveloping leaks there. I dont know if my truck was due for the leak ( at time of leak I had 127,000 miles) or if it was due from the 2cycle oil I was adding to my tank.
I now have '07 cummins 6.7 and looking to improve my mpg's but I think I will stay away from adding the 2cycle oil. I have talked to numerous diesel mechanics and they insist that the 2cycle oil is not necessary for lub'n up. A standard purchase of additive every 3-5 thousand miles will work with any newer model diesel be it Cummins/PS/Duramax will add needed lubricity.

Here's a little light reading for ya. :D

I'll add one from the KING's of fuel injection... (Bosch)
http://mopar.mopar1973man.com/pdf/022003bosch.pdf

Even Bosch points out the American Diesel fuel back in 2002 didn't meet or exceed the requirements for lubricity for there fuel systems... :w2:

Like I said earlier in this thread, I've been running 2 stroke oil in my 04.5 Cummins (with the kitty) now for about 75,000 miles with no ill effects. Currently I'm running at a 1/2oz per 1 gallon diesel ratio. Mopar1973Man can vouch for that. At those ratios in my truck that works out to about a 256:1 ratio of diesel fuel:2 stroke oil...............If any of y'all have 2 stroke yard tools/chain saws etc., you'll realize that this is a pretty thin mixture of fuel. My outboard Evinrude on my boat calls for a 50:1 ratio of gas:2 stroke oil................my chain saw and weedwacker call for a 40:1 ratio. So I hope y'all can see the ratios we're running are real thin. Even the 2nd gens which Mopar1973Man has done all research on running at 128:1 is still real thin IMHO.

Yea... My VP44 is still singin' down the highway pulling 20-22 MPG and no P0216 code. I've got 99K miles on it with over 3 years of 2 cycle oil diet and no problems to report. :U:

I sit here and shake my head to all the VP44 threads where P0216 pops up and the VP44 is wasted due to poor lift pump or just poor fuel quality.

i started add 2 cycle oil to mine within last 2 months and i have to say im a believer mileage went up and runs smoother and quieter. :U:

:U:

been using about 18 to 20 OZs of 2 stroke and sae 30 weight non detergent oil in my truck and it works fine. the TDI gets power service

idk guys... i'm a recent grad and our fuels teacher addimently expressed that sulfur was actually an abrassive and he's an old timer; had his hands in so many pumps ya cant count em anymore... i'm not going to jump up and down and argue with anyone; i just hate to think i paid for an education and what i was paying for was just smoke being blown so i can sit around and fart smoke rings

If I understand it correctly, the sulfur doesnt provide the lubricity - but the process of stripping the sulfur also removes some or most of the lubricating properties.

Just a question here. Not callin you a liar, just making sure I understand this post. Are you suggesting that other 33hp came from runnin 2 stroke oil alone?

4.7 Sulphur

Interesting information there. Apparently Sulphur isn't a lubricator for the cylinders, but the final paragraph states this:

I'm curios too, couldn't that have come from your after-market exhaust? Wouldn't have been the first exhaust system to improve horsepower, I believe.:yeah:

Anyone pouring their old Rotella-T into their tanks? If so, are you filtering it really well, and how? I see it was one of the options in the study, and I believe it would be a great way to get rid of our used oil. From the crankcase, to the gastank, to the atmosphere!:rocking:

Cummins use to recommend this for the ole 12v and 24v engines. It will not work on the common rail trucks.

:humm:
:humm: I'd be leary of this option. Wouldn't it be kinda dangerous with the contaminants of the old oil?

Cummins said to filter it before adding it to the fuel tank. If I recall, it was 1 gallon of oil for every fill-up?

What would be the difference for the CR's?

And yes, I would figure that filtering would be the name of the game for used oil. Like some really strict filtering and refiltering. Probably more than just pulling the left-over fries left floating around in the WVO.

I'm still VERY leary of putting ANYTHING into my tank. However, I have used Lucas, but after reading some of these posts, I think I'm going to stop using it in anything other than my quads!:ph:
