140,000 miles an 03 original owner.Been using Lucas upper cylinder lube 16 oz's every other tank sometimes its every forth tank.But original fuel pump and all 8 injectors

 

I throw in either Motorcraft cetane booster & cleaner or Redline fuel stabilizer. Usually an 8oz bottle once every 3rd or 4th tank. I'm not a real fanatic about it, but I think it keeps the injector demons away.

 

From what I have read the acetone is not intended to be an injector lubricant or cleaner. It has nothing to do with injectors. It is all about how it interacts with diesel fuel. It reduces the surface tension in the diesel fuel molecules which enhances diesel fuel vaporization during injector spraying. The more the fuel vaporizes when sprayed the more complete the combustion. That equals to more power, less fuel consumed and less carbon contaminates going past the rings contaminating the motor oil.

I agree about 2 cycle oil. I contacted Royal Purple about using their synthetic 2 cycle oil in the fuel system. RP said it is a great additive to diesel but becomes expensive if used at every fill up. About $6 to $7 a quart. I use a quart of RP 2 cycle oil about 5th tank of diesel.

The acetone strips the lubrication. With the heui injection the fuel lubricates the injectors. I have read all about the acetone stuff it was a hot topic 5 years ago after katrina and everyone was scrambling to save on fuel. The acetone will not eat filler neck rubber and should not cause any harm yada yada yada yes. For a fuel enhancement no. It reduces the total btu of the diesel. There by reducing the energy in the diesel. The only benifit from acetone is the cleansing properties. The lucas product for diesel fuel is actually less lubricating that plain ulsd. If you want to know a lot about fuel additive both pro and com pm me and ill shoot you to a diesel specific thread. Gains with mpg can screw with you head. Adding something to your fuel system then watching for a improvement most will typically drive better and gain milage. I know when the acetone craze was around a few years ago there were 2 or 3 guys that added it to their wifes cars with out telling them to see what kind of improvement it made. Yes on the first tank they saw a increase but after the increase they did a few more tanks mpg stayed the same.... Then when they stopped adding it the mpg did not drop. Adding a fuel system cleaner at every tank is a waste. After the cleaning is done you are wasting product. If you have terrible fuel then it might help but most would change to a better fuel. Did you know that cetane is like higher octane gas? Both slow the burn of fuel. Alcohol and or ethanol both do the same and reduce milage as well. Cetane is good for cold climates only. I'm all for trying something new. If it works for you great. I have etensively looked into fuel and oil additives and in my truck I run a good oil and no additives because adding anything to the oil system will cause foam at 500 to 4000psi which will cause hpop problems and injector issues. You have to have 500psi to fire the injectors For the fuel system I run only ashless 2 stroke oil because it lubricates the injectors. My truck is a early 04 and has the original injectors which don't have the later coating (05+?) which is said to make them more durable. I feel I need all the lubrication that ulsd can't give me. I would use b20 if it was avalible because it is far better for lubrication. Better than lsd. I will still use diesel kleen but only a few times a year as a cleaner.

 

There is no need to spend $6-$7 a quart for 2 stroke oil when you can get it at any wally world for $10 a gallon. It works out to 8 cents more a gallon when used at a ratio of 1 oz. per gallon.

 

Personally, I would only use a fuel additive that has been tested in diesels and approved for diesels. PowerService, Howes, Stanadyne and a few others are fine. There are pro's and cons to each... but they have all stood the test of time.

I would never use 2-stroke oil in a current diesel motor.. and the ratios that have been posted here have no evidence of fact that it is too much or too little to do any good!! Who knows if 1oz per gallon is even enough to lubricate your injectors.. or maybe it's to much and will clog the EGR valve and intake?

Heck... I should post that adding Pert-Plus shampoo and conditioner should be added to one's fuel tank.... it will clean and condition your injectors, fuel pump and the like!!!! I then could post that I use 1oz/gallon and get great results....

Heck... I bet I could add 1oz/gallon and my motor would never even know it was there and run just fine... why... between being diluted with all the fuel in my tank and running high-quality (OEM) racor fuel filters... I bet I would get great benefits... just like 2-stroke motor oil... (cleans and conditions).

My point is... stick to what has been approved and tested in our motors. So much is dependant on the base fuel anyways.... cetane improves will not make bad fuel good... but it will help aid in better firing of the fuel once in the injectors.

BTW... I double-dose with PowerService at every fill-up (32oz per 44 gallons) have have zero problems with my 6.0L... and I now have 149,000 trouble-free miles on my Excursion... so something must be working!!!!

 

Good post!

You can experiement with adding other non-application specific oils or solvents with your $40k truck if you wish. But I don't care what benefit you think you are getting, it ain't going in my motor.

 

One problem with acetone is a similar one to using alcohol - they both readily mix with water and thereby may allow water to pass through the membrane in your fuel filter, ultimately entering your fuel injectors.

You really don't want to do that.

 

To your liking, how many miles would you like to see from people who have used 2 cycle oil with no EGR, or injector issues?

 

When Ford blesses it, or better yet starts selling it, I'll be convinced.

 

Independant testing showed powerservice diesel kleen was just barely above ulsd in lubrication. The same test showed that stadyne was 2x better. 2 stroke oil at half of what I use was right behind stadyne. Yes your right 2 stroke oil is not approved for a diesel application. This is cut and dry simple. It will not pass emission and epa regulation. This is why it is not comercially advertised. I agree you can use or not use anything you want in your truck. I do know that since using 2 stroke oil my truck is a lot quieter.... I think the extra lubrication is the reason... Diesel kleen in double doses is not doing you any better. If you are so finatical about approved items in the truck then why over dose it? Yes you may have 150k trouble free miles heck I have 105k and have the same injectors as it came with in 08/03 does this mean I've done something right? Maybe yes maybe im/ur lucky. I still have the stock egr cooler, head gaskets and bolts and I run a healthy tune.... But I read at least once a day of guys under 100k blowing head gaskets.... Guess I'm just doing it right as well... I know my injectors don't have the added coating that was used in later models... I don't want to chance a failure so I do the best prevenative I can

 

Ford dosent recomend head studs or egr deletes either both are great products!

Read your owners manual and see what Ford recommends as far as a fuel additive. My owners manual does not bless anything. " it is not necessary to add any aftermarket additives to your fuel" Maybe your manual blesses other products.

 

Ford recommends, and even sells, a cetane improver. I just use a different brand, and my diesel supplement manual says that is okay.
