BTW did you know the liquid in these gauges is glycerin (a byproduct from BioD). There are many, many products made from Bio waste, like soap, womens make up, dog food, glycerin, the list go's on and on. So ontop of fuel sales they also sell the waste product witch is good.

And, to confirm Im not against any company making as much profit as possible. I just hate when they pull the wool over our eyes and say "this is better for you! trust me".
Some products have a "good, better, best" rating and charge accordingly. So fuels for diesels should be IMO

Winter blend = good
BioD/Bio blend = better
#2 dsl = best

The difference of the bio fuel raw material, processing, and additives make the difference in messing up lines, pumps, Ip, and injectors.

Not all the fuel companies like running bio in their product. The 2 largest fuel suppliers in Nv loose profit to it, but it is law, so they do it (at least when I worked for them a few years back). One outfit made some wicked junk bio from peanut oil, followed up by high end stuff from soy. same process, way different results.

Methanol / ethanol use in any fuel is to burn cleaner in the name of less pollutants, see oxygenated fuel research. The hilarious part is that pure alcoholic rides like my ol '69 Camaro at one point put out amazingly low smog testable emissions- but try to breathe that exhaust and you'll be dead in a year.

Methane (C1), ethane (C2), propane (C3) and butane (C4) are far better choices for emissions and health of people/ animals but the availability makes it harder to deal with. That is until the demand goes high enough that the refineries decide to crack the hydrocarbon chain with longer run times. That of coarse adds cost to the fuel but is a serious long term possibilities.

As far as the #2 being better than bio- well that is a simple decision of the mfr of the bio. Better product simply costs more to buy. Everyone says they want the best fuel, but then gets upset at high fuel prices. At the company I have been working for doing the plastic to fuel stuff, We created a diesel fuel that has absolutely amazing lubricating properties with almost no recordable sulfur so it burns way cleaner than normal fuels; basically all that and a bag of chips. The problem is by time it would get to market in it's pure form $8 a gallon would not sell. Although you get the bag of chips, you are paying for it. So... the refinery's want to buy it as a sweet crude non distilled and mix with their oil part way in the distillation process. It will make their product better, but cost a little more to the end customer.

It isn't just bio fuels btw. Refineries get their crude from different sources and that has massive impacts on the fuel they produce. Have any of you wondered why trucks in 1 part of the country can get better fuel economy that the same truck at same altitude and driving conditions. There is a range of btu's, flashpoint, reed level, lubricity, etc. that the fuel can fall into. Those ranges have a decent impact on the life of the parts and of coarse efficiency.

Bugs are always associated with bio fuel, but bugs are in conventional fuels (yes gasoline, kerosene,jp4&8,etc) as well. They just are larger in bio, and when it is not treated properly can propagate at 2-3 times the rate in high heat climates. Want to run any fuel without the fear? a dry centrifuge in the truck gets it all, no bugs below 1 micron. DO NOT USE A REGLUR CENTRIFUGE!- EL-BOOM-O! under right or wrong circumstances.

If you really want a rating on the fuel, you can get it from them. You just need a month in hydrocarbon chemistry lessons to have it help yo understand the differences. I've got some time in over the years dealing with it on off, and still have to go "what was that again?".

I'd agree with you on not knowing the quality of the bio being blended in.

After I posted the above I thought, Hey they give us a choice of gasoline fuel at the pump of Reg, Premium and super duper. So why not for diesel?

They do, when delivered from the truck. I order premium diesel with an 11% soy blend.

Around here there are some soy oil processing plants and the quality is very high

*imo* most diesel drivers put in the cheapest crap they can find (says the guy who pours his used engine oil in the fuel tank on his hummer as a lubricant). Big $ to retro fit a gas station and add 1 more tank even if diesel was just offered in #2 and #2 premium. A big demand would have to stand for the retailers to drop the dough on it. I also don't use mid grade or premium gasoline, so I hit the cheap crap guy in that arena, but I would for my diesels if I knew it was worth it.

Also a growing market in the high performance arena it really could be a bug to put back into the ear of fuel suppliers. The more diesels on the road, the better the chance.

The problem is the emmisions. Everyone knows DEF is a hack on a short time span, but cant find a better way to drop the numbers. Unky sam is fighting the addition of more diesels because to move aunt Edna to the grocery store and work it simply pollutes more than gas comparing both conventional fuels. We need someone here to engineer the half breed of the di good power with the lower NOx numbers of the idi.

Believe me when I tell you the fuel industry is trying its 'A' off at cleaner fuel at affordable rates. If anyone out there has a couple million they are trying to invest in alternative fuels, the company I have been working with is SSOOOO close right now it's sick, but we look like we hit a 3-4 month delay (read as sarcastic cheerleader-GO LOCAL GUBMINT!!!) in permitting and such. I know our fuel is way beyond others in lubricity, so good for components life. Also almost no recordable sulfur, so way emissions are a given, but I haven't seen any test data on that yet to know how much cleaner.

Man, If the locals could buy high end fuel straight out of our yard where its processed and would be willing to pay $5-$6 a gallon for the best stuff available...We could make sweeping changes across the Nation. Clear out most the plastic waste that ends up in landfills and take us off so much foreign oil. Not to mention the jobs created. Even in 1 location it would show the retailers it's worth it for the investment of an added premium diesel tank. What say you Leroy, got a couple mil laying around? :hihi:

Seriously a good idea Leroy, it makes sense to me. If it didn't work to give people the option of better fuels, we wouldn't have the choice of gasoline at the retailers.

Back more to the original post, I do think a major killer of fuel lines and seals in pumps is the mix in different fuels. But this isn't a new problem- anyone ever talk to a mechanic that was around before gasohol times? It was a common practice to out all the rubber lines, fuel pumps and rebuild carburetors fairly frequent. The only way you would know if it is wear or fuel issue is to tear apart the bad pump when you replace it. If rubber seal is swollen and mushy- fuel additives. If it is rock hard- air from sitting or methanol. Just plain worn out becomes an argument of natural wear vs not enough lubricity from ulsd.
