as per ford the max allowable bio in a power stroke is b5?? would anyone know why?

• Frequent or extended idling</STRONG>
Over 10 minutes per hour of normal driving
Frequent low speed operation
Sustained heavy traffic less then 25 MPH
One hour of idle time, is equal to approximately 25 miles of driving
*Note: (If vehicle is operated in sustained ambient temperatures below -10°F or above 100°F)

• Operating in severe dust or off-road conditions

• Towing a trailer over 1,000 miles

• Sustained, high speed driving at Gross Vehicle Weight Rating (maximum loaded weight for vehicle operation)


• Use of Any Biodiesel
B5 is the maximum allowable blend to be used in any <----this
Power Stroke™ Diesel

 

I didnt see anywhere on the link that spoke of BIO? The link you posted was just about maintenance, maybe I missed something.

look just above Normal Service Intervals all it is, is the same link to what i posted. i just wanted t know if that was somthing to cover fords butt.
or to show other ford PSD owners that the way i read that is ford is stating that anything over b-5 may void the warranty of a PSD. if they wanted to be a pain about it. that is a ford site and it says the max for bio in a PSD is b-5. i wonder if any of the dealers tell the 6.4 owners that when they buy them or if they just say that all bio is good in the truck? just somthing to think about.

Thanks, I see it now! Thanks

Interesting...I wonder why? Or better yet, from what studies are they basing the B5 limitation on?

BTW, I think Dodge has adopted the same reccomendation for the Cummins...didn't they?

Biodiesel
Many engine manufacturers allow the use
of “biodiesel” in their engines, up to a
maximum blend limit.
Cummins recently announced the upgrade
of its allowable biodiesel specification from
B5 to B20 blends. B20 biodiesel blends may
now be used in many Cummins engines,
including all on-highway, commercial
vehicle engines manufactured in 2002 or
later.
For details on the use of biodiesel in
Cummins engines, please visit:

this is more for big rigs but a cummins is a cummins.

 

I believe that one reason that Ford tries to limit it to 5% is that BioDiesel will cause o-rings in the fuel system to swell and degrade at a much faster rate than straight #2. A small 5% blend will not cause as much of an effect as a higher concentration of bio would.

Most of the factory o-rings used in the 7.3 fuel system are not Viton. As far as I know, the only TSB that Ford issued on o-rings was in the late 80's(?) that upgraded some of the injector o-rings to Viton. Most of the time this swelling is not noticed until something is serviced and the o-ring is disturbed. Many have noticed when working on the fuel lines that connect the heads to the fuel bowl, how the VibraLock seals are disintegrated and wondered why they never leaked. Or why the fuel drain valve worked just fine until the last time they used it.

Due to the acidic qualities of BioDiesel even Viton A will swell and degrade over time. Viton F holds up much better to b-100 (Viton F is a Terpolymer composition where Viton A is only a Dipolymer composition) but the ultimate Viton would be Viton GFLT. The only problem with GFLT is they would cost about $9.00 per o-ring if you could even find someone that has them.

 

Ford won't warranty anything above B5 because bio-diesel is not federally standardized yet. Some states are now requiring bio-diesel to meet ATSM standards, same standards as regular petro diesel. However since this varies from state to state, Ford can't take a chance fixing a truck running sub-par bio. Once pump bio is required on a federal level to meet ATSM standards, then you can bet that Ford and other manufacturers will be required to warranty any blend of bio that is purchased at the pump.

Our trucks and even new PSD's (and other diesels) are all bio-diesel compatible.

 

i see what you are saying. but to me bio is a joke right now. i went to a shell station here in new orleans. i asked them where they got it(b-5) they said some person makes it on GA, but they test if before they sell it. ok how much 3.15 per . cool i take 23 gallons it turns out that i have to pay 3.61 per gallon due to tax. the maker charges 3.15 per but the feds tax the hell out of it. i have to pay .01258 for hazard ins for shell. and then the hwy use tax and them the fed mandate tax for what ever else. my truck likes the bio but i don't like the price and the mpg didn't climb that much. so to me bio is not worth the money until i get a tax brake for the use of it. just my 2ct. but you would think some oil/gas/fuel co. would take all they could from this and start buying fry oil and mix it up. but hey just pushes me to try and make my own. sorry for the rant

 

my father and I are looking into setting up our own bio-d plant. we both have powerstrokes with low MPG and this $3.29 is killing me. He drives an 08 f450 and is lucky to see 11 MPG. and my 350 is lucky to see 12. Something has got to give
