Post subject:  Longer Diesel Life
My wife and I bought our Liberty CRD in April of 2005 and have had no trouble with it. The rear breaks were making scraping noises. The dealer replaced them and no more noise! We get an overall average of 24 mpg and have a little over 7200 miles on it. The reason I joined this forum is … about six months ago the key-lock station where we get our diesel switched to low sulfur diesel. Our Jeep now seems to have a lot more engine noise then before we started using the LSD. I was talking to a friend of mine, who has a Comings diesel, and he said when he switched to an additive called Longer Diesel Life (Produced by Oil Service Fuels) his truck runs quieter, with less smoke and slightly better mileage. My question is: have any of you ever heard of or used this product? I would add it based on my friends experience, but don’t know if the CRD engine would react differently than a Cummings. I know it sounds like snake oil, but good things are said about it on the web, and my friend has been using this for about two years. I would like to hear any constructive comments any of you might have.

The processes to remove sulfur from diesel fuel also remove some lubrication. They as in refineries are putting in additives to get back some lubrication but with profit loss don't expect too much. You can add any of the name brand additives which will help with mileage also. A quart of VIRGIN veggie oil to a tank helps.

It sounds like you're already going out of your way to get the Low Sulfer Diesel already. I would recommended maybe using B20 bio. The lubricating BioDiesel keep my CRD pretty quiet when I use it. It also gets about 1-2 MPG better milage when I use it.

you should be able to find a station using the following website:

You are in Washington, try using biodiesel. B20 is really good, but if you can't find that B5 is even a good benefit.

In fact, many places are planning on using 2% (B2) to get back the lubrocity lost in the refining process for ULSD.

Also, Washington has new laws which require biodiesel use (as a percentage of total state diesel sales) - so you will be seeing much much more biodiesel availability around the state...

Ok guys get the terms right:

Low Sulfur Diesel (LSD) = 350 to 500 PPM sulfur (been manatory for on road vehicles for over a decade)

Ultra Low Sulfur (ULSD) = <15 PPM Sulfur (required after 15 Oct '06 nation wide, CA Sept 1, '06)

What were you buying, LSD or ULSD? Some ULSD is avalable in some markets already even outside west coast area.

Yeah, OldNavy and I being "old school" remember hearing about Timothy Leary pushing some LSD out on the West Coast area back in the day.

According to this posting by oldnavy, the refineries are supposed add lubricity to make up the difference. It should be better for your engine all around.

I'm all for using biodiesel but this whole lubricity thing smacks of fear mongering.

It wasn't imaginary the first time around when we transitioned to LSD in the 90's. Pumps sprang leaks and pumps failed internally. Hopefully it goes better this time.

The common reason for pump failure in the early days of LSD was seal failure, but it actually effected less then 1% of the diesels on road and 5% of farm tractors nation wide if I remember the numbers correctly.

Figures I'd be in the 1%. :roll:

The nearest Bio Fuel is B20 in Odel OR. It is 60+ miles one way. I have three five gal diesel cans and drive to Odel as often as I can to fill the KJ and cans, but it’s a long way to go. Thanks for the info! :D

Keep your eyes open. Washington's new biofuels laws mean there will be biodiesel pumps springing up all over.

What we need for the CRD is a little tanker trailer option to chase down biodiesel.

Post subject:  additive
I use the Power Service to get the cetane up and add lubricity. It is a shame cetane level are not required to be posted on the pump. You have no idea what you are getting when you fuel up. To add lubricity, I have heard some mechanics will add a little ATF to the tank. Seems like it would work. Have not tried it? Any opinions?

This subject goes beyond pump problems. You have to also look at the lubricity requirements of the internal workings of those little electronic fuel injectors with close to 24K psi behind them.

Common problem in Detroit Diesel products when LSD was introduced. Detroit's don't have a central injection pump, instead each cylinder has it own pump in the form of a "unit" injector that is powered off the cam/rocker arm. Inside that unit injector is a small electronic solonoid valve to control injector timing (similliar timing mechanism to electronic common rail injectors) which became prone to failure/jambing when LSD was introduced.

VW uses the PumP Duce on it's cars, but is I guess switching over to common rail starting in '07 MY from what I hear. They had a lot of problems with proper spec oils to keep the cam from scarring.

I agree that the lubricity thing is the talk of fear mongers, and if you just always use an adative till everyone gets switched over to the ULSD for awhile you will not have a problem with lubricity. Big time true if you buy B2, B5, B10, B20, B99 or B100 fuel.
