Chevron says that cetane rating for low sulfur diesel should be the same.

Scroll down to the last chart to see US and European cetane norms.
The info pages also state that lubricity additives will be added as needed to maintain the levels that the older higher sulfur diesel had.

There will be additive for lubricity in the ultra low sulpher diesel. The pipeline that I load at is putting in a tank for the additive right now. We should be pulling the ULSD by next month.

From Chevron's website mentioned TxLED being a minimum cetane rating of 48.

Anyone know if this new ULSD will produce less smoke ??

Will the exhaust smell be any different ?? Hopefully, it will be less NOXIOUS!

I'm running TxLED fuel and I don't see any smoke. And this is with the EZ on.
I did a 300 mile round trip last weekend towing a enclosed car hauler weighing in around 6k lbs and after this trip noticed there wasn't any soot on the rear bumper. Normally the bumper would have a fine layer of soot on the exhaust side.

I for one am excited to get ULSD.


Remember that sulphur is NOT a lubricant! Sulphur is a hard yellow mineral that's actually ABRASIVE.

The problem (and source of much misinformation) is that the process that removes most of the sulphur from diesel to produce ULSD also reduces the lubricity of the remaining fuel.

Thus, it's a simple matter of adding some lubricity enhancement during the refining process.


The higher cetane rating of the new fuel is also going to be a GREAT thing. American diesel fuel is known the world over for poor quality, perhaps just barely surpassing Mexican fuel.

I wouldn't mind 50 cetane at the pump with good lubricity... but even 46 is a huge improvement.

Here's a link to a map that shows where USLD is already available.

WAUCONDA, Ill. (Dec. 6, 2005) - About 45 miles west of downtown Chicago, Diana Mikelski finds herself in ultra low sulfur diesel heaven. The supervisor of transportation for Wauconda CUSD 118 said all 51 of the school district's buses have been running on ULSD since March and the smell couldn't be better.

"You're expecting diesel smoke, and you get this clean smell," reminiscent of bleach, she said. "We literally had a cloud that would hang over our bus yard; not anymore. The teachers have noticed it more than ever."

Now my wife won't mind riding in my SMELLY truck!!

Don't know if I should call it amazing or typical that the EPA is so screwed up that they are calling ULSD low sulfur diesel on that map.
Low sulfur diesel is what we have been using since 1994.

So the ULSD has more of a bleach smell to it? Wow - I'm going to have to check with the place I fill up all the time.... I've been smelling something like that from the truck the last couple of weeks. Maybe they've already switched.

For any of you in the St. Louis area, I usually fill up at the Quik Trip at Mid Rivers Mall Drive in St. Peters.

Infidel,

I think you're right. I've read some more about it. I tried to edit my last post to that fact but I think I accidently deleted it instead. Daughter jumping all over me while watching Nemo.

This is what it said:
All dispenser pumps must be labeled based on U.S Environmental Protection Agency (EPA) guidelines and indicate the sulfur level and designation of the fuel. For example, any dispenser with S500 (500 ppm of sulfur) diesel fuel must declare that the fuel is not suitable for fueling model year 2007 and later vehicles.

WARNING

Federal law prohibits use in model year 2007 and later highway vehicles and engines.

Its use may damage these vehicles and engines.

I wondered what happened. After I saw the post I was replying to was gone I deleted mine as well.

what is the sulfur content of the current diesel? that sucks that diesels won't smoke and smell like a diesel any more. i've been having fun driving next to hondas with their windows down and lettin her rip
