Low sulphur vs ultra-lo sulphur diesel?

[Minnie's Mate]

Thanks for the link Westfalia. It never ceases to amaze me the breadth of information can be found on Wikipedia, yet I never think to look there for info on any given topic.

Thanks also TBSafari28 for the additional information. Between the two post and the info at Wikipedia, I have a much better understanding of the DPF and what happens with sulfur in the exhaust.

My '05, and now my '08, constitute my first experience with diesels so I am kind of skittish about anything that might damage them. With the high cost of repairs I would rather spend a little more on the maintenance and go a little out of the way, and even pay a little more, for fuel than to risk damaging any component part of the system. I was told by my regular service provider that one of the reasons that my '08 uses more fuel than my '05 did was the ULSD. After reading the article I understand that it isn't necessarily the fuel, but the regenerative DPF system that may be part of the culprit in that issue.

I just sold my 2000 F250 PSD and have a 2008 F450 on order.

One of the managers at our local Ford dealership, who is a truck specialist, told me he recommends adding a good quality additive to every fill-up in these new diesel trucks.

I've seen the results of an independent study on these additives effect on diesel fuel lubricity conducted last summer that was funded by advertisers and others on The Diesel Place.

The study results showed that 2% REG SoyPower Biodiesel was the top additive as far as increasing lubricity (I donlt even know where to buy that), followed by Opti-Lube XPD, FPPF, Opti-Lube Summer Blend and Opti-Lube Winter Blend, (in that order) and then others.

Some of these additives improve cetane, contain anti-gel agents, are bio-diesel compatible, etc., plus have a rather wide range of costs. Some of the older additives on the market are not even ULSD compliant and may damage newer diesels.

I'm no expert by any means on this subject. However, I'd like to add an additive if there's going to be some positive impacts in doing so. Is there any single additive that is the BEST one?

Also, how important is it to put the correct amount of additive in your tank when you fill-up? I don't know if these proportions are anywhere near to being correct, but if they say to add 4 oz of additive to 10 gal of diesel for example, can you guess what is 4 oz and maybe get in 3 or 6 oz instead, or do you have to be more exact? (I often just eyeball the amount and pour some in to my tank).

hi 'fisher...

f-450, oh man i love it!

started looking into a srw version of that model myself.

imo the stanadyne (performance formula) link provided in post #13 is the best overall additive.

they do after all, make diesel fuel injectors.

it did/does improve mpg slightly. i did the measurements (with/without, towing/not towing) and as long as fuel is priced above 2.80 or so...

the additive cost is offset by the small mpg increase.

it also addresses ALL of the other diesel fuel issues.

i've read the 'report' too and until it's repeated, remember that op-teee-lube is the primary sponsor.

i've found 20% and 100% soybiod locally, (lots of web sites for finding this stuff) and add just enough for a 1% bio formula...

haven't done careful with/without comparisons on the bio-d, like i did with stanadyne...

the take home message on bio-d is, very small amounts and frequent fuel filter changes....

let us know MORE about that 450, over in the 2008 superduty thread!

cheers

I see that the Stanadyne Performance Formula does just about everything except make your monthly finance payments on the truck, and since its non-alcoholic I guess you can't even drink it in a pinch! But, it's pretty costly. Know a good place to get it by the gallon or so at a better than avg. price?

Looks like their Lubricity Formula additive is a fraction of the Performance Formula's price and does practically everything except have the cetane booster.

'fisher...

my understanding is that boosting the cetane rating a little improves go power and mpg some.

that may be part of the value in bio-d which generally has a higher cetane rating, but lower energy content...

use the 'dealer locator feature.

i purchase the 1/2 gallon jugs from a local independent diesel repair/service shop, i found with the locator function.

performance JUNIOR is the 'value' priced product...

the fellow who runs the yahoo powerstroke group does sell this snake oil on line, from his web page (which is EXCELLENT 4 powerstroke info)

scroll down to the turquoise box (store) midway down the page...

dieselmann's Page

but shipping would be cross country 4 u....

my local price is 22-24$ per 1/2 gallon

one point of user feedback...

this stuff has a REALLY strong odor. don't carry it in the cab and wear gloves when pouring.

and we want PIX of the new 450!

cheers
