guys - I have a 6L...with this new ULSD, do I need to add a lubricating additive with each fill up? What is recommended?

 

From what I have heard is that USLD is less lubricating and it is highly recommended to use an additive (This told by the service department at the ford dealership). I use Powerservice White bottle (Anti-Gel) for the winter months and grey for summer (every fill up). An additive is cheap insurance for your injectors because those things can be spendy. Others run an additvie every other fill up or once a month. I'm not sure if you really need it for every fill up, but for me it peace of mind.

 

They said the same thing when they went to the low sulfer fuel.
Lots of vendors, some good, some maybe not so good, take advantage of these "the sky is falling" changes in diesel fuel to sell you something.

 

the ulsd has alot less lubricity that lsd. the refiners are mxing in lubricity additives themselves as a requirement. the new fuel is supposed to meet the same lubricative test the lsd did. but you never know what kind of fuel you have, so i suggest always use some kind of additve mainly dk or powerservice because these are more popular and less chance of a problem.

 

From what I've learned from my fuel supplier and my cousin who is a engineer for chrysler is that IF your vehicle was designed for high sulfur diesel then it is a great idea to use a additive in each tank. The going from +500ppm to 15 ppm of sulfur is the main reason. Yes the lubrication is correct for going to the LSD but going this way off is not good for the older diesels (pre 93 era).

 

Diesel Kleen has been recommened here on FTE and is on sale at Schuck's Auto Parts 2/$10 (they carry both grey and white bottles with anti gel). One bottle treats 100 gallons. Cheap insurance for me.

 

Why is it we automatically don't trust the diesel fuel to be good, but we put blind trust in an additive to cure its alledged shortcomings?

 

I thinks it's the ounce of prevention is worth 10 lbs of cure thing... I never had any problems running without the additives, but after reading all about the injectors and the lubricity issues, I figured it can only help. I like the boost in the cetane rating too. The weather has been below zero already around here. I'd rather not come out to a bowl of jello in my tank on the off chance someone screwed up with the load of diesel I just filled up with.

 

so the diesel kleen I buy at WalMart...grey bottle for winter and white for summer provides the added lubrication? Thanx for the patience guys...

 

Jdogg: That would be white for winter and grey for summer.

Just read the labels on the containers. The one with the anti-gel (white bottle) is what you want in winter. The grey does not have anti-gel and is what you want for summer. The grey also provides a little more cetane boost than the white.

As far as my experience, just the cetane boost alone is worth it. These engines respond well to more cetane. Mine ran smoother.

 

I have used Marvel Mystery Oil in my tank since I have been driving. Have used in both gas and PSDs. I use about 4oz. to a fill-up 30 gal or so. I swear by it. Never had a problem with valves or injectors. BTW I'm 64 yrs old.

Jdogg,

Check out Stanadyne on our site, it's the ONLY OEM approved additive so you'll never have an issue at the dealer.

Kinda has something to do with not having to post the cetane value of fuel on the pump, much like octane on gas pumps, the fact that diesel comes complete from the refinery with an acceptable ammount of water and sediment in it, accepted percentages of contamination from traveling in a multi product pipeline, the list just goes on and on.

 

Mark since when is Motorcraft not oem approved?

 

I just bought 2 bottles of cetane booster and performance improver from the local ford dealer this past weekend, it said on the bottle WARNIB: Do not use in 2007 model ULSD Diesel engine.could cause damage to engine. This was right off the bottle of a ford product what gives ???
