I have a 99 F-250 SD with the 7.3 PowerStroke. I ran B-100 until it got too cold to do so then switched to a 50/50 mix of BD and PD.

It's been about 5 months now. I'm not sure of the milage, I'll have to look it up.

So far no ill effects. The truck only had 60k miles on it so apparently there was no sludge to break up and collect in the filter. I checked the filter, it was clean. I changed it anyway and kept the old one to use as a back up.

I wash my fuel but am going to making some batches of unwashed BD to experiment with. This stuff will be setting for a period of months to evaporate all methanol off and also for soap to settle out.

My washing and drying processes are the most time consuming of them all and it unwashed fuel will work with not ill effects I'll defineatly be using it.

I would think that if you can afford to leave the fuel sit for a period of months, somewhere around 4 months or more, you are going to get about the same fuel quality that you would if it were washed and dried.

My only real concern would be byproduct getting into my tank. That cannot happen! What ever need to happen to prevent this I'm all over it.

I believe that settling for a sufficient amount of time would be the trick. I suspect that after some set period of time all byproduct (glycerol) will have settled out and that unless some how methanol and catylist were introduced into your fuel tank, there could be no additional byproduct available thus there being no more to settle out.

I understand that there is some amount of time that the reaction will continue. For most it's not an issue because they are washing and therefore stopping the reaction and removing all potential ingredients that could allow reaction to continue.

Question for the experts, Am I on the right track with my logic about after a period of time all reaction will be complete and eventually will settle out will occour and will be no way of having any more byproduct to settle?

Or am I all wet?

I am running 96 f-250 with the powerstroke on a b20 mix 50,000 miles no problems yet I have run b-99 in the summer but only after running b-20 for an extended time (to clean out my tanks my truck has 400,000 miles on it.

$800 bucks to switch out some o-rings - OUCH!

Anyone?

Sorry to drift from the main thread, but what sort of MPG does an F250 get?

Don't know about anyone else, but I'm getting 18-20 mpg. No difference running B50 except considerably quieter.

Is B50 the highest you would go?

What is the latest year of Ford pickup trucks you'd run B100 on?

I am. No problems so far.

I also run b100 in my 97 with no problems. It really runs much better than dino ever did.

Read some at superdutydiesel.com too. Not as much hostility as the other one recommended.

What are you trying to convert to? your posts are misleading.

WVO- Old body style trucks on WVO- there must be thousands of them on the road. The usual warnings apply. Later trucks too. nice thing is the filter housing is in the valley=>heat into the fuel.

BioD: remember bioD is a replacement fuel. the usual warnings apply. later 6.0 motors have enough problems, so switching to bio or wvo is not really recommended.

PSD bioD use is out there. many many miles with no problems.

worry more aobut your fuel filters unglueing than your orings and the like. that and the cleaning effect of biod will clean your fuel system up pretty good.

Ford specific: 84-through mayby 88 was 6.9L normally aspirated
88-94 was 7.3. NA/and later Turbos
94 on is powerstroke, PSD.
03 was change to 6.0 PSD.

PSD is a unit injector motor. uses high presure oil to actuate the plunger in the injector. the orings people refer to seal the injector body to the housing. replacing them is not THAT bad, just a PITA.

you should look into some of the other ford sites too.

the drama stop- www.thedieselstop.com

for higher levels of bio, filtration and fuel heating will be an issue.

I've started running some unwashed fuel in my '99 F-250. It runs no differently. The only thing I have noticed is that my water in fuel light comes on periodically. If I drain the water seperator on the engine, it will stay off for 20-30 miles. It never stays on constantly. The stuff that comes out of the seperator looks slightly brown. Anyone have any ideas if this is glycerin left from the unwashed fuel or the bio starting to clean out my system?

would like to know if you have had problems as of late

Have two 97 powerstrokes been running bio since nov. 05 havent had any problem til late both have had lose of power, wont go above 30 mph at times. Changed fuel filters, cleaned inside fuel filter housing. just changed cam sensor on one last week and running alittle bitter can go to 65. they were also had the rpms jump up to 2500 with no power. Looking for some answers. thanks I do have two MB and a Jetta all on b 100 that are working fine. thankyou

I've had a similar set of problems on a '93 F350. The BD ate the plastic that held the fuel pickup screens inside the tanks. This released some sort of string material that clogged the fuel tank selector (about $160 from Ford as the generic version has wrong size connectors). It was a ***** to figure out. Okay, I didn't, I just kept 'fixing' things from the fuel filter going backwards until the truck started working again.
