Can of worms "Additives"

[tightgroup]

I have searching for a good additive for my Burb.. After searching the net to get some sort of viable information, I ran into this;

Which seems to make sense! Now given that we accept their conclusion based on the tests, we should come to an understanding that adding a mix Bio in the nature of 2% does wonders for lubricity...

Now the question..

Do the oil companies add Bio to their diesel fuel ?? If they have a B98 or a B95 would that not be the cat's meow ???

Oh BTW I was looking at the materials list for Opti-lube, and it seems that the primary ingredient is naphta

I experimented with BIO 5% additive one summer... The next time I changed my fuel filter there were LARGE hardened white deposits inside, almost size of marbles... I've never experimented again.

I go SAE 30 ND, 32oz per 18gallons of fuel average. Heavy mix, runs nice and smooth.

I think Illinois and a few other states mandate it, but most of the other states do not at this point. It would make sense for the distributors to add a mix to aid in the fuel lubricity though.

I want to add this was me adding B100 into #2, not a state-wide pre-mix.

I think the State-wide pre-mix is a FANTASTIC idea. Not only does it help lubricity, but it also gives american farmers work. I wish all states did 5% pre-mix, at least in the warm seasons.

state mix is up to 10 % here in il. i put 20% in my 6.5 once. didnt really notice anything except a drop in fuel milage.

Minnesota has a 5% mix minimum by law:thumbsup:

Careful what you wish for.

The stuff you see in the fuel filters is the Bio cleaning the fuel system. First tank or two of bio can plug your fuel filters 2x over as it cleans out the fuel system.

Your lift pump's valves will dissolve in biodiesel. Older hoses and seals also can dissolve. LSD also affects these hoses and seals anyway, usually stuff made before 1995.

Methanol is used in the process out here and the source of lift pump issues for me. (I used something like 1400 Gal of B99 in 2009.)

The DPF systems on 2008 with post injection DPF cleaning put the biodiesel component into the engine oil. It will not vaporize off or out of the engine oil no matter how hot you get the oil, trust me I have had the oil way hot.

10% penalty in fuel economy. It may improve in a mixture other than B99.
Less power.
It smokes less.

The fuel smells bad.

B99 will get the dirtiest running military surplus engine through the snap test for emissions.

Cold weather requires a #2 mix as the cloud point is high for B100.

And the tax credit for B99 just got put back into place. Better investment than the gee wiz Sci-Fi hydrogen or other exotic waste of taxpayer money fuels that lack an infrastructure to deliver. I can use B99 now and get it delivered in 275 Gal tanks that can sit in my yard. It is safer than #2 diesel and not an environmental hazard if spilled.

The LP's valves will dissolve in B100? I hadn't heard that before. Both my rigs run B99 during the summer months. I replaced the LPs on both, but when I looked at the old ones - they didn't seem to have valve dissolving problems per se. Yes when I ramped up my biodiesel usage, I needed to do it slowly (over several tankfuls) and then replace filters as they clogged up, but I am very happy with how the 6.5s are running.

Been running B5-B20 for years. It's more readily available now in Illinois than straight #2. There is a penalty in mileage of around 5% or so. Winter is typically B5 with #1 mixed for winterizing. Can't beat BIO for lubricity but IMHO it's not enough so I run Power Service year round in almost every tank. White bottle in winter and silver bottle in summer.
