I've heard a lot now about how bad it is for emissions equipment anyone know about running a 6.4 with removed DPF and EGR and running b5 or B20? just curious

 

I am deleted and run B-20- B-50 in the warmer months with no issues. I run optilube in the winter.

 

Thanks how many mile stare you up to? Any repairs related or not...

 

Are not stare*

 

I have a 2010, 33,350 miles, deleted since 15,000 I think. No issues, no one touches my truck but me, oil every 5k,fuel filters every 10k, syn oil and fuel additive every fill up, stanadyne in the summer/warm months and optilube in the winter.

 

Does anyone know if all Murphy stations are using biodiesel now or does it depend on the state you're in? I have a 2010 6.4 and one of the first things I did was delete the dpf, so I'm not concerned about bio being harmful as far as the dpf is concerned. I do buy a lot of diesel at Murphy USA though, but I've never noticed the B5 or any other sticker on the pump. Just wondering if I've been putting biodiesel in my truck without realizing it, and if I have, should I worry about it since I've deleted the dpf.

 

Not sure where you r but the corn states all have laws mandating bio, mostly B20 or as close as they can get. I spoke with some folks from Loves and they told me in the states where the bio is not mandated they take whatever makes them the most money which depends on the available government subsidies. They also say the stickers aren't required until B5 (I think it was B5) then there is a different requirement for B11 or above which I think is a B11 sticker.

I don't think the B5 rating for the 6.4L has anything to do with the DPF. According to the service manager I talked with in Michigan it is a concern about seals and gaskets. I don't know for sure and neither Ford nor the
national Bio board will talk to me about it.

The EPA has a study of the effects of bio on DPF technology. You can find it posted under my signature back a couple years. Bottom line is it increases fuel dilution but they didn't think that was a problem. I do, but many on here use it all the time and love it. I avoid it when I can, I have 160 gallon fuel capacity and I can get through most of the corn states, even towing. Hope this didn't add to the confusion.

 

Parkland whats the best fuel to buy in BC then?
I buy most of my fuel at Husky but if I read right they have more bio content?

 

I have used lots of Bio from B-5 to B-20 in my 08 F450 with what I feel is no adverse effects whether it be regens or mileage. I currently have 84K on the truck. I towed my 38' Mobile Suites from SoCal to Indiana the Southern Route and back the Northern Route using mostly Bio and I was over on my oil change interval (changed at 6K) my oil analysis showed 3% dilution which was only 1% more than my earlier 4K change, only mods are Bank's Six Gun and Banks Ram Air, run the tuner at level 3 & 4 when towing and I get better Fuel Mileage just don't push it and watch your temps. I cruise at 60-65 with 4:88s. When I have a choice between Bio and straight I choose Bio because it's cleaner, plus I always add Schaeffer's Diesel Treat.

 

When I had my 6.4 I ran a few tanks of bio that I could not avoid. While I had no ill effects my mpg's suffered greatly.

IL is where I picked it up at. It was only in the tank a few hours though.

 

I really cannot detect difference in mileage maybe its the Schaeffer's Fuel additive which increases cetane, currently using B-20 exclusively while at home from Propel Fuels

 

I noticed Murphy DID have B5 stickers on their pumps then they were taking them off when I was filling one day. I haven't used anything other than Shell in quite sometime.

 

I've dredged up this old post with some new information.

I live in Virginia near I-95 and within 20 minutes of a Pilot, a Flying J, a Love's, and a TA. I now have 112,000 on my 6.4 and have deleted the DPF, CAT, and EGR, and added an H&S tuner (all done at Rudy's Diesel).

All the truck stops near me are now running either B5 or B10 and will be going to B20 by the end of the year. I checked with my Ford dealer and they said absolutely, positively, under no circumstances, use B-20 in my truck. They also said that there was no way to adapt the engine to accept B-20, such as re-programming. I did not mention that I had deleted the DPF, etc. In online checking of truck stop fuel prices and blends, it appears that B20 is the (unfortunate) wave of the future.

Does anyone have any new information as to possible damage to the engine?

 

Most of the concern is sitting on your garage floor. The DPF won't take so kindly to the extra soot that is produced due to the lower energy content of bio.

I would run an additive to ensure good lubrication when B20 hits.

 

Thanks Senix. I always use Ford's cetane booster.
