CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.

Ah...here are the results. Great find Jeff and the results concur with the study that I posted in your earlier thread. When independent studies concur, I pay attention...Biodiesel, at 2% or greater, is easily the best lubricity improver!

 

Interesting information. Any similar results regarding mileage improvements?

 

Some one please tell me how to add rep points? There are several threads like this that I believe deserve Rep points given, and I have no clue as to how to do so.

 

so # 2 on the list is thist stuff here right?

http://www.opti-lube.com/XPD.htm

isent rep points added by clicking on the upper right hand corner of the users box next to post #? just my gues..

 

Look at the upper right-hand corner of the post (next to the post number)...you will see a little set of scales - click on the scales and enter your comments.

 

Do I need to be a supporter to do this, because when I click, it just gives me their status, by the way, nice job in gaining momentum, see, I clicked....

Thank you.

 

What they have is diesel that is UNADDITIZED. I would be interested in seeing what diesel is really like at the pump. Now, what will it translate to by bringing it down to what the manufacturers want? IOW, how much more life will it give my car? On a manufacturing scale, it is significant because of warranties but what about on a user scale?

 

has any one used that opti-lube XPD stuff and think its worth the $?

 

Until we can put a dollar figure on the difference between HFRR 520 and whatever it can put you to, how would we figure out what it's worth? IOW, if it costs me $500 but saves me $600, we can figure it is worth it.

 

Well... @ $4.35 per tank (assuming a 29-gallon tank here), to pay for itself you would need to save $4.35 worth of fuel. With diesel here in Birmingham running $2.74/gallon, that amounts to roughly 1.6 gallons of fuel LESS than what I would normally use for the full 29 gallon supply. Since I am overall averaging 16 mpg, my 29 gallon supply of fuel lets me travel 464 miles (29x16=464).

So, if I go the regular 464 miles and only have to fill up with (29-1.6) 27.4 gallons, then I have saved that 1.6 gallons of fuel to pay for the additive. My mileage at that point is 464/27.4 = 16.93 mpg. Now, the web site indicates that you get greater than a 5% increase in mileage. When you look at the 0.93 mpg increase and calculate the percent increase, it comes to an increase of (0.93/16)x100= 5.83%, which is, in fact, consistent with the advertised benefit.

So??? If you use only the fuel savings, there appears to be a realistically potential 100% payback in fuel alone. This doesn't take any credit for the "value" of reduced scarring and wear in the injectors and engine. If you accept the report at face value, and place real value on the wear reductions reportedly associated with the using the additive, the potential for real payback increases.

However, there is another issue in the pot here, and that is the fact that this report was done on diesel PRIOR to any additives being injected by the manufacturer or distributor of the fuel. What now? Does this mean that the potential for payback is reduced or increased?

That, my friends, we do not have information with which to even propose an answer... not yet, anyway. Maybe someone else has some information that compares the impact of these types of additives on "base" fuel and "additive-enhanced" fuel from the dsitributors before these consumer additives are put in at the pump by some of us.

Until we have that information, though, it's going to take someone biting the bullet and making the purchase, using the product for a length of time, compiling the data, and starting another thread with the results... and THEN..... living through the barrage of challenges here in FTE regarding "how accurate were the measurements", "was it a blind study", "did you put it in and take it out and repeat the trial for verification", .... etc.

 

If you are looking for increased lubricity, nothing...NOTHING...comes close to 2% or more biodiesel. I saved the cost of 10 ozs of Diesel Kleen (about $1.50 a tank) and from reading the study, biodiesel increased lubricity by a 415 micron improvement compared to DK's 61 micron improvement...that's nearly a seven-fold increase in lubricity for $0 increase in fuel cost. I'm just asking, but why use additives for lubricity when you can have the best by purchasing 2% or greater biodiesel?

 

415 Micron from what? I calculate 299 from ULSD at the pump and not unadditized fuel.

How does it not increase fuel cost if it has less power? How much reduction do you need that will make a difference? Is 520 acceptable? 420? 320? Does anybody really know what the acceptable number is? Manufacturing wants fuel to have more lubricity. To them, even a tenth of a percent translates to big bucks. However, to the end user, it may translate to going 10000 miles more at best. To the manufacturer, 1000 miles may push you out of warranty zone so they might be more keen to recommend it. Now, until someone can show me what the difference between 520 and 420 will bring, what does 200 matter?

 

Only an option if it is offered to the public in your area. Not here yet (publicly) only fleet fueling islands have it and I don't know their codes. Although Alabama is building the largest biodiesel refiery in the nation currently. It is near Tuscaloosa Alabama. soon we will have the bio.

 

Can someone educate me a little, please? What is HFRR? What does the micron improvement number mean, and how is it interpreted?
