ULSD vs LSD

Okay, went on a roadtrip to Burns, Oregon this weekend. 300 miles there with ULSD keeping it under 70 and 2k. 15.4 mpg. Filled up in Burns on LSD and kept the same driving style on the way home. Got 19.1 mpg! I have had my truck for a year, but have only had ULSD because Washington and EPA crap. That was the best mileage I have ever got. A co-worker of mine had the same experience with his Duracrap. Anyone else experienced this?

Did they say it was LSD in oregon or did the label just indicate that it was LSD? I found alot of stations in WA with out dated label saying LSD.. After talking to the attendants, they say it has been ULSD for several months now..I really have not noticed any fuel mileage difference since they switched..

Maybe he means Lysergic acid diethylamide (LSD). After that stuff you surely start to see these kinda mpg's

They said it was LSD. The reason I thought it might be LSD was the CFN station next to the Chevron gas I filled at was also offering LSD. I know that Washington is on a ULSD kick, wasn't sure about Oregon or other states.

I've read that the labels aren't necessarily outdated, but that during the switchover stations run USLD through their tanks for several months until all the residual sulfur gets cleaned out. Evidently it's up to individual stations to get their fuel tested to make sure that it meets the 15 ppm standard.

Quick question, is it OK to run ULSD in the 7.3 or is any sort of additive or changes required?

"Officially", it's safe, but it lacks the same amount of lubricity as the older fuel. Most of us either run a Bio mix, or some type of additive. I use Diesel Kleen, really because I get it at Wal-Mart in the big bottle around the same time I need to buy my oil & filter. It treats 300 gallons, and 300 x 15mpg = 4500 miles...

Here in South Texas I filled up Friday in a Exxon truck stop and it was saying LSD? It was much cheaper ~$2.57. This in the industrial area so it could be real stuff?
I don't know but somebody was saying, you can get much better mpg's with that LSD?

Is there something in the Law about the LSD and ULSD? Obviously the law doesn't count in South Texas as we can't get Bio here (closest city 150miles), neither Ethanol (250miles)!
We are too close to G.W.B ranch?

Nope... The first "***** Gas" (Bio Diesel) station is within 50 miles of "The Ranch". I've been by there many times (***** Gas Station, not The Ranch).

Ethanol can be had at the new HEB in Sharyland. The closest place to get Bio is SA.

I saw an article in the TDR magazine on this subject awhile ago. The new ULSD is supposed to have a special lubricity additive to make up for the refining process removing most of the natural lubricity in LSD. The original plan was that it would be put in ULSD before it left the refinery, but the owners of the major big pipelines objected that no tests had been done to prove that this new additive wouldn't somehow screw up their pipelines or cross contaminate other products shipped through them. At the last minute just before the introduction of ULSD it was decided to let the local fuel distributors add the lubricity additive just before the ULSD was delivered to the filling stations.

The article speculated that this wasn't the best approach, as there were no safe guards to insure that the correct amount was added prior to delivery, and also voiced potential concerns that adding too much after market additive might conflict with this new additive. I've not seen any follow up to suggest that this "over medication" is an actual concern, and I still add about a X1.5 dose of Stanadyne.

There is a fuel station close to me that sells a fuel called "CF Roadmaster" and it is an on/off road LSD fuel. It is NOT dyed. It was $.05 MORE a gallon than the regular ULSD. I am going to do a search on it....heck, I might make the 18 mile drive more often to get it.


Quoted from a Cenex site:


Benefits of CF Roadmaster
Maximizes power and fuel economy for pulling long hills
Provides quicker starts
Improves fuel efficiency
Prolongs injector and injection pump life
Cleans the fuel system and keeps it clean
Protects the fuel system against rust and corrosion
Reduces warm-up time, misfiring, noise and exhaust smoke
Reduces water retention and emulsion problems
Reduces sulfur and other emissions
Exceeds the National Conference of Weights and Measures criteria
for premium diesel fuel


Complete additives package
Cenex CF Roadmaster Premium Highway Diesel has a uniquely formulated, balanced additive package, along with a high-quality base fuel for highway use. CF Roadmaster’s exclusive performance additives work together to provide maximum power and longer engine life:
High cetane content promotes quicker, more fuel-efficient starts.
Aggressive detergents helped CF Roadmaster obtain a superior rating on the Cummins
L-10 injector cleanliness engine test, assuring maximized power, fuel economy and component life, with minimized smoke and filter plugging.
Lubricity components protect the injection pump and injectors from wear and
premature failure.
Demulsifiers reduce water retention and emulsion problems. Once stored fuel becomes contaminated with water, it begins to deteriorate, resulting in the corrosion of your engine’s fuel system. Demulsiblity characteristics force any water contamination to the bottom of the storage tank for easy drainage.
Corrosion inhibitors keep rust and corrosion from forming on the internal parts of the fuel pump, extending pump life.
Stabilizers reduce gum and varnish build-up that can clog filters on tanks and
diesel-powered equipment.

CF Roadmaster is a smart fuel choice. Protect your diesel engine investment with Cenex CF Roadmaster, now available at (DISTRIBUTOR NAME). Stop by and fill up today.
