Any of you guys use this when you fill up? I used to use it on every fill up when I had another diesel. Thinking about putting 4oz's in and see if I get the benefits I did on my old beater.

DON't put Marvel in anything!!!!...use it to break nuts free that's it.

It is better putting used motor oil in, rather than using that Marvel crap.


These results are listed in the order of performance in the HFRR test. The baseline fuel used in every test started at an HFRR score of 636. The score shown is the tested HFRR score of the baseline fuel/additive blend.
Also included is the wear scar improvement provided by the additive as well as other claimed benefits of the additive. Each additive is also categorized as a Multi-purpose additive, Multi-purpose + anti-gel, Lubricity only, non-conventional, or as an additive capable of treating both gasoline and diesel fuel.
As a convenience to the reader there is also information on price per treated tank of diesel fuel (using a 26 gallon tank), and dosage per 26 gallon tank provided as “ounces of additive per 26 gallon tank”.

CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.

We were using ATF in the hmmwvs over seas with a lot of success. The 6.5 & 6.2 had problems in the heat which we found ATF to almost completely cure. We were replacing injection pumps every other week until we started adding ATF. We were adding 1 qrt per 20 gal tank. After I got back I did a bunch of research and found the biggest problem was the low quality fuel, which the added lubrication and cleaning of ATF helped. I also found a lot of people here were having success with 2 cycle oil. Since then I have been adding 1/2 qrt of 2 cycle oil per 30 gal tank in my 6.5td, which helped the mileage a little and it seems to run a lot smoother with it. I also use power service in every tank, and have never had gelling problems.

I don't intend on using the 2 cycle oil in my duramax, but will continue with the power service for now. I have been looking at switching to amsoil fuel additive or the opti-lube stuff. But am not sure, because they only clean and lubricate or boost cetane, not both like the power service. And I've been doing good with the power service. I don't know if the duramax would benefit from 2 cycle oil or not, but I believe ATF can add its own problems, such as dying the fuel red, and possibly causing pump problems, although non were confirmed.

I am thinking about going with the opti-lube summer blend in addition to amsoil cetane boost for summer, and haven't figured out what to do for winter yet.

CP3 does not require any additive as they were designed for the Calif fuel table from the very beginning. However, putting an additive ( 2cyl, ATF, bio ) in the fuel of a Dmax will make it run much quieter. See other threads concerning 2 cyl.
ATF doesn't cause any problems with the CP3 up to '07.5, My buddies and I have been running used, filtered ATF along with bio for several years without any problems. ATF is an old farmers trick for mechanical pumps (ie, 6.2, 6.5 ) which gives additional lube to keep the plungers from seizing and the ring from wearing out.

I'm wondering if anyone can recommend a good fuel additive for my LB7. I have always used Lucas, but after reading Tank's Thread and some others, I'm not sure that I'm using a great product. I live in a warm climate so winter additive isn't needed, but I'm looking for a good cetane booster and a good Injector cleaner.

POWER SERVICE ~ Diesel Kleen available at Wal-mart.
Silver bottle is cetane boost and to some degree, injector cleaner ( white bottle is anti-gel ).
My cousin and also several friends say they have seen an increase in mileage using the Silver, all located in central Florida. I use it when I'm not running B100.

BIOTEC, thanks for the info.

After reading some facts on here and other sites, looks like Opti-Lube XPD scored the highest, it's a bit more expensive than others but I'll p/u some Power Service next time @ Wal-Mart if the Opti-Lube doesn't pay off.

You are more than welcome for the information
Keep in mind, the CP3 was originally designed for the California fuel table and does not require any additional lube other than what is contained in the fuel itself. Now, having said that, I can also tell you that if you do run an additive such as Bio-diesel, 2cyl ,ATF, ect... the motor will not be near as loud.
There are two separate issues here:
1)cetane boost and/or injector cleaner and
2)lube to quiet the motor.
Power Service will keep the system clean and probably increase your mileage to some degree. I haven't seen any complaints on this brand yet.
Using an oil additive is to keep it quiet and probably adds life to the CP3.
There are other threads posted that are related to this issue (2 cyl oil, bio fuels and additives, ect) and virtually all say, there is a noticeable difference in how much the 2 cyl oil quiets the motor. When I run Bio or ATF, it makes a big difference in my truck. Good luck to you in whatever you decide.

Just wondering, How much ATF do you use per gallon/Tank of fuel?
I can't give you an oz. per gal because I filter used ATF to 1 micron, then add it to the tank. Some times I add 1 gal, sometimes 5 gals or more, but keep in mind that I'm using it as an alternative fuel source as well as a lube.. I would start with 1 qt on the first tank, drive 50 miles,then add a 2nd qt, see if you notice a difference. The farmers normally added 1 qt per tank for their tractors, loaders, combines and 1 - 2 qts in their diesel pickups, that was back in the days of 89 cent or less ATF. If you are going to use new ATF, it will be more economical to use 2 cyl at the rate of 16 oz per 26 gal tank which is close to a 200:1 ratio. I don't think brand makes that much difference in this application, most appear to be using Wal-mart SuperTech.
1 - 2 gals of B100 bio diesel usually keeps it quiet, 5 gals makes the exhaust smell very unique, like model airplane fuel.Do not use straight veg oil that hasn't been processed into bio, we found through trial and error, that it leaves a varnish type coating inside your fuel system that is very difficult to remove.
Whatever you use, add it to the tank and then fill up.
Most of those commenting in related threads seem to notice a difference within 25-35 miles from fillup.
Hope this helps.

Are you in the service?
