Hello FTE,
Maintance and serviceing a Diesel engines are all new to me so be gentle. OK I have been using the fuel

additive that the local dealership parts department provides, but I'm considering an alternative method. They

want $8 for that little bottle. I believe it's called Power Source. I'm thinking about using a 50/50 2 cycle

synthetic motor oil with Stanadyne Lubricity formula. I would put in roughly 4oz for 15 gallons. Does this

sound ok for the 6.0? Can I add a cetane boost to this mixture? However, is it more important to have the

lubricity or the cetane boost with ULSD fuel? If you useing 2 cyle oil. What formula are you using? Can the fuel pump, injector, etc be damaged or clogged with all this added oil in the fuel? Thankx

 

I try to keep it simple. Don't fix what ain't broke. I use Redline fuel stabilizer for diesels. A bottle is about 7 bucks. I use 1/2 a bottle every 2nd tank. Keeps the injectors clean & idles smooth. Outside of that, change the oil and filters when your supposed to. Some guys like to pour lots of additives into their engines, but I haven't seen any proof that it really does any good. If the truck is running good, why mess with it? Just my 2 cents.....

 

It's because it's all anecdotal. I have yet to use anything in my truck and I haven't had the problems that people are saying that they had before using all this "stuff". My mileage has not gone down since using ULSD and knowing that there are alot of factors that play into mileage it's hard to pin bad mileage to any one thing without knowing the numbers or behaviors of the situation so I fail to see the need for a cetane booster or for additional lubricancy with regard to the "lack of" lubricancy with the ULSD. It may very well not have as much(more then likely it doesn't unless they added it in after processing the extra sulphur out, which I believe they were supposed to, to the same consistancy as before that I don't know), however I have yet to have a problem with regard to that and until I do, I don't believe it's necessary, it may be one of those things if you use it it won't hurt anything, but it may not help either.

 

Thank you for your quick responses, but I have a few questions. Where do I buy this Redline fuel additive? Also, if your theory is that no additives are necessary. Then why are there warning labels placed on the diesel pump in regards to diesel engines 2007 or newer? Thankx in advance. GO BLUE

 

The only warning labels that I have seen are for the LSD pumps and that is because the LSD has too much sulphur then the filters on the newer engines can handle, not because it needs more lubricancy. If your seeing a different warning label let me know because that is the only label I have seen.

 

ive been using rbp's additive lately i like it better than the d.k.

 

You may want to read this test report before you make any changes --

Nice report...thanks.

Like so many other things, this issue comes down to personal preference and philosophy.

The process of removing the sulfur at the refiner has a secondary effect - it reduces the lubricity of the diesel fuel. The distributer is then responsible for adding treatment chemicals before it goes into the tanks at the gas station. We see Valero tank trucks delivering their fuel to Exxon and Shell stations locally. Even though it may be Valero fuel, the additives will be Exxon, or Shell, etc.

As stated in the study, from the link posted earlier, the government sets a standard for lubricity that these "add packs" are to shoot for. This target is different from the recommended standard set by engine manufacturers and injector manufacturers. The government standard allows for more wear in the tests than the engine manufacturers and injector manufacturers.

The question is like insurance. How much wear is acceptable? Do you want the best you can get, or meet a standard set by the government? Also, I have seen and experienced "bad fuel" from the pump. A friend of mine just recently did also. The use of a water demulsifier can really help your fuel filter protect your fuel system IF you get bad fuel OR if you get condensation in your fuel tank.

Certainly a decision for each person to make on his own. It probably will not show any benefit in the short term - mainly long term benefits (unless you get bad fuel).

 

I put in some Motorcraft fuel additive today. What a difference in low end throttle response. 2004 F350 6.0L crewcab long bed dually. I usually have a trailer on the back and didn't really notice the loss of power, attributing that to the trailer. I was driving around with it yesterday and it just seemed sluggish up until about 60mph. 60 to 90 has always been pretty impressive. I guess the cetane boost is what pepped it up? I used to use a different additive but lost a couple of injectors at idle speed and my fuel sender locked up a couple of times. The fuel sender has worked fine after suspending the fuel additive. I will be on the road with a trailer tomorrow. Anxious to see if my fuel mileage improves.
