Do You Use a Cetane Booster

[DonandJudy_12]

I have used either Stanadyne or Diesel Kleen for years- The mechanic I do business with recommended it and I have confidence in all he does and says- I can't prove useage helps but I am at ease spending the extra cash- We all know that the fuels available are suspect because of the quality or lack of- Proper maintenance has always been the reason we get the service we get from our TV's- JMHO- Don

we have used diesel kleen since day one in our 08 Ford on the advice of the diesel tech at Ford. It has to be used in every tank to be effective. The newer diesels 08 and up require a cetane rating of 45 to 50 to run properly and few fuels have that rating. When I can find Shell premium I will use that as it does have a higher cetane rating. There are several good sources on the internet on the issue. It would be a good idea and educational to.. look it up.

I run Opti-Lube in my Ford. I started about 2 yrs. ago after I met a couple of other RVers that use a cetane booster in their TV.

It was based upon the report Bucky provided that I began using XPD last fall. My interest is in improving engine operation and longevity and it was second best over all in those categories. I am not sure if the Diesel Kleen listed in the report is the same as what others indicate they are using, but the Diesel Kleen in the report did not fare well though it was much cheaper.

[richfaa]

I think the diesel Kleen listed as # 10 is the same stuff we have been using which is strange as the Ford Guys recommended that saying is was as good as any out there and the same as the Ford stuff. I will have to re evaluate that. I do know the truck runs better using it.

I use it for lube and preservation.

Every 25 gals my 6.7 Ford Diesel gets 5 oz of Motorcraft PM-22. Ford product and the recommended additive for the new Ford Diesel 6.7. Anything to increase Cetane. I used Diesel Kleen for many years on my 7.3 Ford.

Thanks Tom It looks like I need to switch to XPD. The test they did looks like a good valid test. I will investigate farther but I think I will be buying a couple gallons.

I have the older 7.3. I always use Motorcraft additive with every tank. I had to have some o-rings replaced in the fuel filter bowl due to lubrication problems with the new low sulver fuel.

We use what Ford recommends....from them of course...but we have had no troubles to date....so we keep using it...also where we work I can get it for. 25% discount by the case....so that helps...

I use Amsoil cetatine booster for a duramax GM diesel. Stop and go driving of d I use every fill up. Running diesel all day , every other tank. Amsoil booster also cleans injectors. My d is a 2001 with 140000k.

I'm another user of Opti-Lube. It contains a cetane booster, but my primary reason for using it is to add lubricity to the low sulfur fuels, and thus hopefully extend the life of my injectors.

I bought a gallon of the Opti-Lube XPD. They sent the test results that Bucky573 had a link to. In the test they used 1/2 ounce per gallon which is the winter blend. The summer blend is 1/4 ounce. I wonder how much difference did it make to use twice the summer rate. If you used twice as much of of the Stanadune Performance Formula, which I normally use, how would it test?

In Minnesota we have a 5% bio blend, so lubrication of the fuel system is not a primary concern for me most of the time. However I use fuel treatment on a regular basis. I've used Diesel Kleen mostly over the years but this year I've tried two others. Howe's premium treatment (forgot the name), not the regular stuff. Went through two bottles of it and it seemed to help the engine run smoother and get better fuel economy than the Kleen. I just started using another brand a few weeks ago. XDP Diesel Power Plus. So far I'm quite impressed with it. It's mail order for me. I needed a few other things so I ordered a couple bottles of summer and winter formulas. Cost per gallon is lower than anything else I have seen. It is one of the few addatives I have seen that include a biocide. My Duramax runs smooth and strong with this stuff in the tank. If you get the chance to try some, I'd reccomend it. XDP is a diesel performance shop. This is not XPD (maker of opti-lube).
181,000 miles and still running strong.

Seems like most additives are being used after warranty mileage. Anyone using anything in new diesels?

[mlh]

The new diesels need a diesel additive more than the previous models. The high pressure fuel pumps run at higher pressures. My HPFP will go up to about 255000 PSI the new ones will go up to 30000+ PSI. Machine shops have a machine called a water jet that cuts steel with water and abrasives added. They run at 55000 PSI and will cut steel over an inch thick. They will cut thin steel without the abrasive. Just to give you an idea of how much pressure that is.

I agree. Even more important to use on newer engines. That is unless you don't plan on keeping it after the warranty expires. Additives also help reduce the effects of moisture in the fuel system. Which can cause a surprising amount of damage within the fuel system even in miniscule amounts. This is even more important for diesels that sit unused for periods of time.

And remember if you damage your fuel system it is up to an $8000 repair bill and is normally not covered by your warranty either original or extended.

I get confused on additives as some "additive product" companies actually name specific engines for specific product. As an example I think the GM LB7 issues with injectors was corrected with GM LMM engine so does that suggest using a different additive for each type engine with unique issues???

[woodtic]

The Duramax injector issues were corrected on the LLY (2004.5 - 2005).

There were a few products specifically designed for the Ford 6.0 injectors. "Hot Shot Secret" is one such product but, their fuel treatment can be used in any diesel engine with good results. Their main product for the 6.0 injectors was actually an engine oil addative that was quite effective. Some products were developed in cooperation with individual manufacturers and receive that endorsment.

Addatives do vary considerably in composition and price. The main reasons to use an addative in your fuel is to add lubrication, control moisture, prevent algee from growing in your tank, and prevent jelling of fuel in cold climates. You don't want to use any fuel treatment that contains alchohol. You also want to avoid addatives that state "for use in gas or diesel engines", some are ok, some are not. You should also be aware that if you have never used an addative and start using one, you MAY plug up your fuel filter in the first few tanks of fuel. This is mostly due to dead algee being removed from the tank. So, watch for signs of a plugged fuel filter. It's always a good idea to keep a spare fuel filter in the truck anyways.
