A friend sent me this test report on various diesel fuel additives and the respective additives ability to reduce "wear." Very interesting....have any of you seen this test and/or the results. I'm always skepetical of these "test" wondering the validity/accuracy of them.

Very good info your friend sent you. We have been discussing this issue in another thread the last few days. Some taking the position that these fuel additives are necessary and some (like me) who say they are a waste of money. The thread was started by Awall and is called, "Best Fuel Additive for cleaning??"

 

this has been on sooooooo many times, test was done in 2007...... only thing I don't get is why they didn't test the 2 stroke oil at higher usages...... one quart per tank like most folks use........ if 16 oz did that good, I wonder how 32 oz would fare?

 

rob- Yea, I noticed the thread and didn't want to hijack it so I posted the info here.

mik- I agree and did a search for the name listed in the link and didn't found nothing but it may have been posted using another title. Anyhow, I agree on your comments but I'm guessing the testing had to limit the "quantity" at some level or volume.

my comments: I was kind of amazed at the beneficial level of products I have never heard of and their high rating in comparison to products I have heard of and their lesser rating/benefit. The only other thing I wondered was who the "independent testing labratory" was? Thanks for the comments.

 

The test was done by an independent lab in Texas by a guy from the Duramax forums. He also is not involved with any companies. And I agree they a should have used a full 32oz of 2 stroke oil which is what most folks use. It shows how good bio is though.

 

Thanks for the comments. At least now someone searching for fuel treatment results will have answers.

 

So I guess running B-11 and 2-cycle is a pretty darn good thing...

 

Actually, I believe the test was run at 2% biodiesel concentration, I'm sure B11 would be even better. The current market price of biodiesel for me, equals $1.14 per tankful at the 2% concentration used on their test.

 

So why do you lump all fuel additives into one category and say they are a waste of money?

 

It doesn't matter what brand we are talking about. It doesn't matter what testing has taken place. Even though some actually have lubing benefits, I lump all additives together because they are all unnecessary in my opinion.

Now if someone just has to add something to give them piece of mind that's ok. But it doesn't change the fact that additives are unnecessary.

 

Ditto! No telling if the results would have been twice, three times, four times, etc as good??

Two points left out of the test that, IMO, might make a big difference.....
1-"... this sample was acquired PRIOR to any attempt to additize the fuel for the purpose of replacing lost lubricity. In other words, it
was a “worst case scenario, very dry diesel fuel” that would likely cause damage to any fuel delivery system."
Not just worst case scenario....possible unrealistic scenario! Chemist that formulate diesel fuel additives work with the chemical structure of the additives already in place...to augment them.
IMO, would have been a better test if they used fuel from the pump.
2-They tested fuel at 140*F. My fuel runs through my engine at 160*F and higher. It's possible the additived tested perform differently at a different temp? The EP package in gearlubes consists of Sulfur, Phosphorous and Chlorine: each of which 'kicks in' at a different fluid temp.

That being said, the test may be valid as a relative comparison of which additives work better than others ..... with the exception of the 2-cycle oil.

As to are lubricity additives needed and of value? As always, that's for each member to decide for themselves.
IMHO, it's hard to argue with smoother, quietier idle and better mileage!
