So I have been looking around and haven’t run into anyone running tunes on B100 or really B100 in a none tuned truck for that matter. I was concerned since this engine has a HP common rail fuel system that there may be problems running this fuel. So I wanted to see for myself, worse cause i am ready to upgrade the fuel system anyways so if major problems arise my original plans will be accelerated. I recently purchased a biodiesel processor and am going to give it a try, so far I have ran 180 gallons of B100 I’ve made with no issues and still using the Spartan 210 tune. The only things that have changed are about a 2 tenth drop in fuel mileage and a slightly different exhaust smell and very little black smoke.

I am being very tedious with the fuel I am making to follow an ASTM grade B100 fuel quality.

Just curious if anyone else has tried this or has thought about it.

 

What about an additive to ensure your HPFP is getting some lubrication?

 

From what I have read and studied the B100 actually has a lot more lubrication values in it VS conventional USLD petroleum diesel.

 

Well that is good. I guess that would be my only concern.

 

B-2 has more lube than diesel......

 

I'd be concerned with an awful lot more than simple lubrication.

FUEL DILUTION

GASKET, SEAL PROBLEMS

Halfway down page:

Fuel gelling:

Anti-gel doesn't work:

Causes problems with brass and zinc fittings:

Your engine is spec'd to run maximum of B5; if you have a fuel system problem running anything in excess of 5% bio, your warranty will not help you. Ford has been known to send lab techs out to take fuel samples before approving major warranty work.

Replacing your fuel system can cost upwards of $9,000 depending on which dealer does the work. Should you damage an injector and cause engine failure the repair can cost upwards of $15,000. I STRONGLY recommend staying far, far away from B100 with a 6.4L engine.

Use it at your own risk.

 

I would not suggest this to anyone who is not informed with Biodiesel, I have done a good amount of research prior to deciding to try this, I am trying this simply because I haven’t seen it done and people seem to say it wont work without hard facts.

Well it’s not hard to test your own biodiesel to know its cloud and gel point, which I have. My Fuel is primarily soy based and shows no issues down to 26 degrees, in my region our coldest days are around 28 degrees. In southern Nevada. There are products available specifically for biodiesel that do stop the Biodiesel form gelling. People rarely talk about them because of there cost and the fact its much simpler to blend in diesel for winter use.

As far as the interaction with metals yes I agree raw biodiesel is corrosive. Properly washed and processed ASTM grade Biodiesel should have a neutral PH and should not cause such issues.

Warranty wise with no doubt you are correct, anything over B5 would void the warranty out, but as I mentioned I am not to worried about that as I can easily do all the repairs myself.

It will be intresting when i send out my first oil sample to see what the affects of any dilution has on the oil

 

[QUOTE=SANDDEMON08;9727313]I My Fuel is primarily soy based and shows no issues down to 26 degrees

I have ran for years , B100 is good down to 50* f any lower and you will have problems. B50 - 40*f B20 - 25*f (FILTERS, FILTERS) Bio works better the hotter temps. with the 7.3s

 

Sounds good sanddemon, looks like you've done your homework! Let us know how it works out for you!

 

Good or bad i'll keep yeah posted.

 

Well figured id throw an update in its been a couple more weeks now since I have been running this fuel. This last couple weeks has been pretty cold for us, 30-35 to night. Imp also running it in my 6.0 which doesn’t seem to like the colder weather, looks like my fuel is only good down to about 38 degrees at B100, I never had any issues with my 6.4 but I am running a little blend now 25/75 diesel and bio so the 6.0 will be happier. I think the fuel return system on the 6.4 helps heat the fuel up a lot faster in the morning than the on my 6.0. Haven't had any filter issues yet. I know it really hasten been that long yet and I haven’t used the truck as much as I normally do but so far so good. Including what’s in my tank now I have used about 240 gallons so far.

 

Nice! Keep the info coming! Though, I probably wouldn't try it because I don't have the mechanical know how to tackle one of these 6.4's, but it is still really neat to see someone trying it. Maybe one day when I have out driven my warranty I might try it then... Who knows!

 

I have never researched bio at all but apparently the B5 warning for our trucks is due to the DPF??? Thus the reason you potentially wont experience any trouble??

 

Time for an update, well its been another few months and around 300 more gallons with no issues. The only changes i have made is I added a 5 micron filter to the BIO station to improve the fuel quality i was using a 20 micron. 25/75 Diesel/BIO seems to be a good mix no cold weather problems down to 40 degrees. I should have my oil sample back soon to see how much fuel/Bio is getting in the oil over a 3,500.00 mile span, i would have had it earlier but i forgot to drop it off a few times. I have racked up about 8,500 miles so far using this fuel. I haven't changed my fuel filter maintenance still changing the fuel filters every other oil change or about 7000 miles which is what i did prior to switching to Bio diesel.

 

Drain water weekly, fuel filters every other oil change, you will have no problems!
