premium diesel fuel
 

Was at a local gas station and saw a premium diesel pump in between the normal pumps for $0.10 more a gallon. Tried to look for info on pump didn't see any plus it was cold and windy. Any knowledge would be appreciated.

maybe the normal is bio and the premium D2?

Maybe it's formulated with less water! :)

I was born in 84 and don't even think i'll be around when that happens! :-missingt

Is it G-diesel? I heard you could get it down the mountain from you. When it first came out it was clear and the EPA didn't like that. I heard it was degraded a bit now but don't know for sure. People use to report better MPG.

Speaking as one who sold diesel additives (but no longer does)...

Premium Diesel has more additives to further improve lubricity and combustion characteristics, and the fuel's "cleaning package" is improved as well. It is not uncommon for a fuel additive supplier to work out a commercial deal with jobbers and fuel terminals to offer this "premium" product by installing the required additive injection system for those customers who will purchase the premium product.

Is it better fuel? Probably, but that depends on whose additive is used and how much additive is being added.

Is it worth it? I can tell you with a certainty that an upcharge of $0.10 is fairly competitive with using something yourself like Diesel Kleen, FPPF, Stanadyne, etc., and there is some theoretical payback at that price point. However, I also know that the Schaeffer products are less costly to use and have equal or better results, which means that you can do the same job yourself for less money (except you have to fiddle with purchasing the products, keeping them on hand, and carefully dosing the right amount when you fill your tank). That's why some people say that $0.10 is "worth it" at the pump when you can find the premium product.

Oh, by the way... the fuel jobber/terminal's cost on this deal is typically much less than $.02/gallon of fuel treated, but that's because they are buying in large volume bulk orders , and generally with a 1-2 year contract. All this means is that for roughly $0.10 per gallon, you get to choose where you want the profit to go... to the fuel additive manufacturer, or to the local jobber/terminal company.

Figure what treat cost is for power service diesel fuel suppliment. Bet its a lot less than .10.

Diesel Kleen has a few "Premium Diesel" stations selling diesel with their additive

They go beyond just adding their additive, including year around additives, including winterization, semi-annual tank manintenance, semi-annual training, and fuel sample testing against 10+ ASTM standards.

I buy my Power Service at Walmart. It is 7.88 for a 32 oz bottle which treats up to 100 gallons. It works out to roughly 3 dollars for a 40 gallon tankful or 7.5 cents per gallon. If I buy it in the gallon size it is 18.00 a gallon or about 4.5 cents a gallon. So yes, adding PS to the fuel is less expensive than an extra .10 per gallon but not by much.

Correct me if i'm wrong but isn't it a half a dozen to the other... 2 stroke oil, power steering, ATF, specialty additives.

Don't forget about the cetane.........

In addition to additives - Premium diesel products are about cetane numbers (also shown in the pdf file jps47 linked).

Diesel engines operate well with a cetane number from 40 to 55 (cetane index is different). Fuels with higher cetane number have shorter ignition delays, providing more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher cetane number fuels. The performance benefit starts to plateau off above 55, so more isn't necessarily better at this point.

As Pete alluded to - In the US, most states follow the ASTM D975 standard as their diesel fuel standard and the minimum cetane number is set at 40, with typical values in the 42-45 range. Premium diesels may or may not have higher cetane, depending on the supplier.

For example -, Flint Hills refinery in Minnesota offers a Performance Gold Blend premium diesel with a cetane of 42-46.

Performance Gold Diesel.

and a Performance Gold Blend Plus with a cetane number of 47-50.

Performance Gold Plus Diesel

In addition to cetane, premium diesel often use additives to improve lubricity, detergents to clean the fuel injectors, water dispersants, improve biodiesel blends and seasonal anti-gelling additives.


California and Europe set a higher standard......

Interesting to note -California diesel fuel has a minimum cetane of 53 (so they are already at the "premium level") and Europe has a minimum requirement of 51.

Lubricity seems to get the majority of the attention since the introduction of ULSD in 2007. Most likely because the engine manufacturers wanted a higher standard (lower wear scar) than what was accepted.

B-10 or B-20 takes care of any lubricity issues.

It sure does, I run over the border to Minnesota during the summer to fill up once in a while.

Does 2 stroke oil contribute to cetane rating or only lubricity?

Ive been told to add 1 ounce of 2-stroke oil per gallon of fuel and Diesel Kleen...I think bottle indicates 8 ounces per 21 gallons of fuel....cant recall at this moment.

It does not increase cetane. There is no "correct" amount of 2 stroke oil because its just something a guy somewhere came up with.

Cetane is very expensive, majority of additive packages have cetane enhancers not actual cetane in them

Here is a chart from Southwest Research's Diesel Fuel Lubricity Test back in 2007 when the new ULSD fuel was introduced. It gives a comparison to what was available in the market at the time the new fuel formula was introduced.

This was one popular chart 6 or 7 years ago!

Here is a link to the full study:

http://www.natbiogroup.com/docs/educ...%20results.pdf

Jay, Tray, Pop & Pete have seen this posted about 100 times over the years.......good info, would be nice to update the study with some new products and reformulation of old products that has occurred.

Id love to redo it. If I could...

2 stroke oil contributes to the asphaltine content of the fuel, which plugs the fuel filter up sooner in it's attempts the filter out the asphaltine.

I certainly hope someone does a new study, I wouldn't be surprised if most of the products on that list have changed formulas by now.

Asphaltene is more of an issue with crude and heavier refined oils versus something like two stroke oil though. Besides that, I don't think it makes a noticeable difference seeing as it is so heavily diluted in our tanks. I'll take a closer look when I change my filters here in a few weeks.

I will mention one observation with two stroke oil, it seems to have cured my noisy #3 injector. Something not even Diesel Kleen could do, and I'm a firm believer in that stuff after using it in my old 7.3 IDI.

State of Maine allows up to 3% wvo to be added to diesel fuel and not be required to disclose the amount. All of the large fuel distributors were doing it because they get some sort of government kickback for it. Usually it just covers the cost of transportation to get it to its destination, but back in the day when people were complaining about lubricity, Maine people weren't having issues when filling up at the truck stops and major brand fuel stations.
I've always been concerned with people putting 2stroke oil or ATF in their fuel. Where I'm from the dot doesn't take too kindly to red colored fuel on the roads. Make sure you use the blue 2stroke oil if you do. I'll stick with diesel klean products and opti-lube.

I used to use 1/2 ounce per gallon. Diesel Power mixed at that ratio in a additive test they did a few years ago.

The problem with the 2 stroke oil is you need to add so much of it that it makes a big ol' mess. I use a graduated funnel with a valve and lid but its still a mess.

Stanadyne Performance Formula.

When the 7.3L was in current production, Ford and International recommended Stanadyne Performance Formula in a couple of service bulletins. (This surprised me, since Ford private labels three diesel additives under the Motorcraft brand).

It saves money ordering the Stanadyne by the case (6) of 1/2 gallon jugs, and then transferring what is needed into smaller bottles that seal well. I have never found Stanadyne Performance Formula at any retail auto stores (that all sell Diesel Power Kleen). But for some reason, every professional diesel injection rebuild shop I've encountered seems to carry the Stanadyne, and not so much the other brands.

Get one of the 1-pint containers and just refill it from a gallon jug when you need to add to your tank. That is what I do anyway, no funnel and no mess.

Not only is it one of the most expensive products on the market, but it still under performs compared to more popular alternatives according to that 2007 test. Doesn't seem that impressive to me.

Which shops have you visited? I have yet to find that stuff available from ANY shop/retailer that does injector work or sells parts for these trucks... Not even my local dealerships carry it. :confused:

The list has two Stanadyne products on it; lubricity formula and performance formula. The lubricity formula is right below the 2 cycle oil.

If it has bio-diesel mixed in the diesel, that should be all the lubricity you should need. Even just a 3% mix.

Here ya go, can't believe I still had it. This was a major "pain in the buts bulletin" when I was a Schaeffer Sales rep......:-jammin:-jammin:-X06

I completely agree. B100 is nice too; I like when my exhaust smells like a state fair funnel cake :)

So in the context provided, "products such as Stanadyne Performance Formula" are the most acceptable. BUT, only for "1999/2000 E&F-Series Super Duty & Excursions equipped with 7.3L Diesel Engines operating in cold conditions".

I don't see where that mentions or has anything to do with ULSD or lubricity... :confused:

x2! :-jammin

It doesn't. I was just adding this SB to Y2KW57's post about Ford recommending Stanadyne in a couple of service bulletins since they had there own line of additives available through Motorcraft. I don't have a copy of the other SB so I only had this one to post.

As for me - I've used Schaeffer's for years and will continue to do so. With an occasional summer soybean bio mix....:-drink

Oh! My mistake, I thought that was the SB meant for the bit about ULSD etc.

No problem Dave, it happens all the time :-X03.....I have a way of confusing everyone with my posts - especially when I post & drink beer! LOL:-jammin

Story of my life! :-drink

I should have clarified, reputable shops like the ones that sponsor these forums. Shops like Rosewood Diesel, Swamps, Full Force, Casserly, etc. You won't find it on any of their sites, or even retailers like RiffRaff for example. Hundreds of people have good things to say about those shops, I could care less about certifications.

Speaking of, I recognize 2/5 certified shops you listed that are local to me. I went to them first when I was rebuilding my engine a couple years ago. I found out that neither one of them build injectors, they only sell brand new ones to the tune of ~$3000 a set. One of them couldn't even test my old set of injectors! Of course this isn't the case for every local shop, but in my case do you really expect me to trust in a business that has no experience with their product? I'll trust in what I know works, thanks.

It's really no surprise that a shop certified by Stanadyne would sell Stanadyne products, honestly.

Huh? It was not intended to be a "surprise". It was intended to find the most efficient and direct way to reliably answer this:
