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.
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.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.
POWER SERVICE ~ Diesel Kleen available at Wal-mart.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.
You are more than welcome for the informationBIOTEC, 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.
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.Just wondering, How much ATF do you use per gallon/Tank of fuel?
