So, I am not a fan of fuel additives, I have resisted using them all the way back to my 18 wheeler days, they are a PITA to keep up with, tote around, dump into the tank before fueling, blah-blah-blah...
Back in my 18 wheeler days, I had only used some anti-gel, and only a couple of times at that, and no use at all in my diesel pickups.
But, since my CP4 debacle and repair, I have been using the Opti-Lube XL (edited) lubricity additive to try and keep the new pump from the same fate as the original and try and give myself some peace of mind.
Anyway, a guy I know, diesel shop owner, tells me I should try the Archoil additive instead, says he uses it and swears by it. So I contacted them and they assured me their AR6500 would do as good a job with lubricity as the Opti-Lube, plus it would help lower regens and increase fuel economy and boost cetane rating. They also offered a discount if I would try it out, so I bought 2 of their large bottles, each bottle will treat up to 400 gallons.
Now, the Opti-Lube adds about 4.5 cents per gallon to my fuel cost, with no increase in fuel economy, the Archoil costs more than twice as much, will add about 10 cents per gallon to my cost, but promises to increase fuel economy by 8-10%.
Now, I know verifying an 8-10% fuel economy gain will be difficult, and I don't know how it would decrease regens since the computer pretty much schedules them when I am running without a trailer.

So, I have a job this weekend and will be running about 2400-2500 miles, half towing, going to test this new stuff out and see if I can tell any difference.

We'll see...

 

Theres a thread on this in full down in the 6.7 section. Debate going on about the regen and fuel economy. Its a battle between Archoil and HotShots EDT. I just started a trial of Archoil sine I have been using EDT for years. I need a few tanks to get results, but the drop in temp and switch to winter blend makes it difficult to truly determine results.

 

One thing I can tell so far is it STINKS!
Smells fishy to me, hope it doesn't make the exhaust smell like that!

 

AR6500 claims to increase your fuel milage because they are raising the cetane number in the fuel you put in the truck by "up to" 8 points. Sounds good but cetane numbers can vary from state to state. In other words, you may be raising your cetane levels, but they still may be lower than what others may get with standard fuel. When you see the term "up to" that means when you max dose the stuff. As an example, Texas is required to have at least a rating of 48 while California has a minimum rating of 53. You might have an increase, but others may get better milage without using anything. I believe all of the major additives use some form of cetane booster.

 

I was never a big fan of fuel additives. A friend of mine who is a master diesel tech told me about Opti-Lube and that he has never had any issues in the 3 6.7’s he has owned over the years. I figured if he recommends it, I will give it a try. I have been using it for a few years now. I carry a case of it when we travel.


Harbor Freight case has worked great for transport. No odor.

 

Seems like alot of extra trash for some added lube.

But then I'm a daily 8-10 16oz plastic water bottle drinker. Leaving my carbon foot print.

One contianer, squeeze dose and done. Back in bed toolbox.

 

Besides the S&S DPK, I use Hot Shots EDT and Better Diesel FBC here.

 

I have 6-2 oz plastic bottles and 6-4 oz plastic bottles that I dispense my additive in, keep them in a plastic ammo box in my toolbox.
That is enough for 360 gallons of fuel on the high end of the recommended mix.
I buy the biggest bottles of additive to refill my small bottles, cheaper per oz that way.
So, plenty to take me a very long way before having to refill the bottles.

 

Archoil doesn't smell half as bad as EDT does, especially after it sits for a while and evaporates, leaving goo behind. If I decide to go back to EDT, then I will reuse the Archoil bottles, the EDT ones can't be refilled.

 

I use Archoil now I have used others as well. Never noticed a drastic change in mileage or performance just hope it helps my FP from not imploding.

I'm interested in following this thread for the results

 

Well, if all I get out of it is its added lubricity qualities, then the Opti-Lube is much cheaper.

 

I will report back any findings or conclusions I come up with.

 

I used hot shots , didn’t notice any difference. Archoil, slight fuel improvement (1.5mpg),diesel kleen seems about the same as archoil. Would not buy hot shots again. Never heard of opti lube.

 

I grabbed some stanadyne additive off rock auto, way cheaper than getting it at TSC. It is the lubricity formula that did pretty well back in the 2006 diesel site study, grabbed a 1 quart squeeze bottle from a landscape supply company and leave it in the tool box for fill ups. No noticeable change in engine sound, performance or MPG but I am just trying to keep the CP4 from seppuku.
