So? How does that help me unless the product is cheaper?

Bio in higher concentration IS known to cause those hoses a problem. Isn't that why ITP Diesel stopped selling their fuel kits so they could get different hoses to make it bio compatible? If it clogs the filters initially, it MIGHT be because it is dissolving the crud in the tank. However, if it keeps it up, there might be problems with the fuel itself since the amount of crud in the tank should be finite.

Dad's tank was spotless and so were 2 others I know of. My MB has 180K on the clock and when I took out the tank to ream the mouth restrictor out, it too was clean. All ran D2. Mine was spotless at 70K. All running D2. What you are saying is similar to the old Chinese legend. A lunar eclipse was because the dragon was eating the moon. How do they know that? Well, when the eclipse occurs, they bang on every metal thing they can get to make a lot of noise. That scares the dragon off because you get the full moon back.

 

The local diesel shops also started doing that. However, last time I checked it was because the seals had shrunk. My IP on the MB also had that problem. Changed the rubber o-rings and life is good. The IP itself was fine. I took a look at their kits. They had kits for 2 out of the 3 (GM, Ford and Chrysler). The kits comprised of seals and o-rings. Now, in the early days of ULSD before they got things going the way it should, if problems arise, that is to be expected with any implementation of a new product. However, if it does that still and in the future, we have an issue. If ULSD was that bad, wouldn't we be grounding half of our fleet of trucks?

 

I've run b100 with no problem.

 

I'm not really sure what you're asking, but I run BIO because I hate the arabs. I do not run it to make my engine quieter. Nice chinese legend, but I don't know what it really means to this thread. I think the quality of the fuel, combined with running the tank low every time has everything to do with what you find in the tank.

 

I'm on my fourth tank of BioD and I've had no problems as of yet. I plan to have a look at the filter this weekend when I install the prepump and intank mod. First tank was approx. B50 and has gone up from there. I filled yesterday with very little left in the tank. I am guessing I now have something in the neighborhood of B90 due to the last of the dino D in the tank. The truck is much quieter at idle and puts out much less thick black smoke when mashing the throttle.

 

What I noticed is that there is a point of diminishing returns on how much bio does. yes it has lower BTU but as I have stated in other threads about this, BTU is NOT the entire equation, BIO has higher cetane and is in fact a cetane boost, it also has different burn characteristics, also bio is an oxygenated fuel thus it provides more oxygen into the combustion process allowing for a more complete burn, which in turn negates or offsets the lower btu rating to a certian extent. Now what I believe from my expereince is that it doesn't completely negate that lower btu but even a small amount of bio makes the engine burn the D2 better and thus you get even more of the energy out of it. What I noticed on my person vehicle when I did some testing was that up to B25 or there abouts I saw a raise in economy (up to almost 2mpg better hand calculated on a couple of tanks) at 30% up to somewhere around B75 it seems to stay pretty flat and even at B80 and up my mileage dropped off slightly.

As to the power, I did a little checking on that too, and although not exactly scientific nor probably completely accurate I will tell you what I found. I tried racing my truck at various levels, where this will lose accuracy is that it was over the coarse of the summer. I was running B100 at the hottest time of the year so that might be part of the loss, and as fall arrived and it started getting cooler Istarted backing off the amount of bio in the truck clear back to straight #2. my first time up there I was running B75, truck ran a best of 9.76 (these are all 1/8th mile times.) july comes along truck ran a best of 9.70 (just couldn't break that into the 9.6s) fall comes along drop back to B50 started running 9.67-9.69, last race in october, much much cooler truck running on >B20 (was switching over to straight diesel but had a little bio in it just not perfectly sure the amount but that is close) truck ran a best of 9.63. so as you can see as I backed off the amount of bio I did gain a full tenth of a second, but i wonder how much that means cause I also went from running in 90 degree weather torunning in mid 60 degree weather.
Tried to be as honest as I could in what was wrong with my little "scientific" test so you can take it for what it's worth but that was my experience this last couple of years.

 

Oh man, you're gonna be mad at me! I meant to give you a good comment on the post and I hit the darn rate button without switching the rating number.

No offense man, good write up!

Can a moderator fix my screwup!

I'm gonna wind up on TV with Britney Spears and the Bionic Woman begging people to buy matresses on infomercials

 

firstl, only 20% of our oil actually comes from that area. Second, what you don't buy, others will buy so all it is you have scored is a phyrric victory. Now if you can get the world to stop buying from them, you may be on to something.

Well, like the ledgend goes, you bang the gongs and the dragon spits out the moon. You know this because you see the moon going from an eclipse back to full. Therefore the gong banging actually works. Same with your case. You mentioned your tank was spotless at 125K. You were using bio. Therefore, your conclusion is that bio cleaned the tank. That would be true IF your tank were dirty. But since you didn't know if it was dirty, the clean tank doesn't mean much

 

Big oil and the regulated return did that for me too. Quietened the engine way more than B50 ever did.

 

Mine remained constant till I went to B40 and aobve and then it dropped a couple mpg

 

I guess I could have been more accurate in my statement, Alan. I should have stated that when I checked my tank at 125k or so, I had never used BIO. I'm a bit of a contrarian when it comes to running my tank low, in fact I usually run it to within a couple of gallons of empty and I think that has a bit to do with the cleanliness of the tank. Plus, the fuel in CA is very good and clean and rarely has any water in it.

I do like the gong and the dragon story though!

 

Actually, it's Andrew. I too run my tank down to pretty empty. How do you think I know that while I have a 44 gal tank I can squeeze in 47 gals?

Glad to make you happy. We do what we can.

 

That's funny, my name is Andrew too!

 

I'll bet dollars to donuts I can buy many gallons of Bio D for what you paid for those mods. Plus you still have to pay for D2.

Why are you constantly arguing against the use of BioD. Do you own ExxonMobil stock or something?

 

If that was all I bought those mods for, you are right. However, I bought them for performance. That it made the truck quieter isn't really much of a bonus. Even if it didn't, I'd still buy them. I can make the truck even quieter by going back to stock programing but I doubt I will switch off my 80 Econo. Only time I am in stock mode is when it is slick outside.

Why are you arguing for the use of BioD? Do you own stock in Biodiesel plants or something? Same stupid question, turned around, isn't it? No, I don't own stock in either products that I am aware of. Even if I did, you can bet I'll be more discreet than that. Bio is another product like the additives to me. I'm not convinced of any of them either. And no, I don't own stock in any of those products or their competitors. I suppose that since I recommend BTS and DP-Tuner and ITP I must own stock in them too?
