Nice find!
It looks like the way they ran the test was very similar to how it was done in the video.

My opinion is similar in that having just some additional fuel lubrication is good enough to lower the chances of the CP4 failing. The other major concern for our engines is degraded lubrication of the crankshaft journals due to contamination from the emissions system.

But as I was watching the video, I kept wondering if the treatment rate made any difference. I'm no expert but I wondered if EDT's lower performance might have something to do with the lower (and cheaper) treatment rate. The top performer calls for 6x the EDT rate at 5x the cost. If I doubled the dosage, would I get more protection?

My last purchase of EDT, including tax, works out to 2.4¢/gal of diesel. It's easy carrying EDT's small bottle with integrated measuring cup to add 1/2 oz every fill up that's typically around 12 gal.

I agree with the sentiment that some additional lubricity is probably going to be good enough. And on top of that not abusing the HPFP, or getting into a situation that will make it grenade.
After watching the video and reading the thread, I started wondering the same thing. The archoil treatment rate is 1.5 times the HS EDT. I wonder how they would stack up comparing the EDT 'performance dose' to the archoil?

I posted this on the JT forum so figured I’d post it here as well


Also after doing some more research on the Opti-lube XPD it appears that product needs the higher dosage for the anti-gel properties.
I really don’t need that being in AZ and most wouldn’t in the warmer months so my plan is to buy their summer formula if I want a cetane boost and mix it with their Extreme Lube and this would provide the best lubricity with cetane boost for half the price of the XPD product.
And if anyone is interested I found the HFRR score of the Extreme Lube Blend shows the best results at 217

There has been 3rd party testing done on many of the fuel additives available, including Marvel mystery oil and that product actually increases the wear scaring as shown in the result of this thread.

Interesting stuff...

This actually brings up more questions than I had before.

So basically the study was done back in 2003 when biodiesel fuel was really hard to come by. And the number one winner for HFRR improvement is to add a 50:1 ratio of baseline fuel to 100% biodiesel.

I just did the math and it was pretty redundant because it tells you right there in that study, 2% REG SoyPower bio-diesel, where 2% is the amount of biodiesel put into each tank of 100% diesel fuel.

So basically what this study found is that your best bet for the best lubricity of your diesel fuel is to simply use a biodiesel fuel mixture. But again that was back in 2003. Nowadays biodiesel fuel is readily available all across the country.

So if this study is correct, we don't need any fuel additives! In fact just buying B5 biodiesel fuel is going to provide plenty of lubricity for all of our vehicles. I actually get all of my fuel at Bucees, who sells 10% biodiesel fuel.

At this point, I might as well keep using Marvel Mystery oil because my lubricity is so insanely good based on the study listed above, that a 42 micron worst score isn't going to matter now. On a more serious note, should we even be using fuel additives at this point?

BUMP

Has anybody seen this yet?

Probably the most controversial thing I've looked into to date on the Jeep.

I wish a review on which brand diesel fuel is best. It's all trash compared to what is used in Europe from what I can tell. Finding the cleanest and highest cetane diesel would be a good choice. I trie to find a station that has a high turnover. Anyone in California using Propel fuel?

Big oil is out to make $$$$ so they are going to produce the cheapest quality fuel they can.
I’m in the Sacramento area and primarily have used Propel renewable diesel since new. Only time I don’t is when I’m traveling in other western states in which case I’m picky about where I buy my fuel from. Haven’t had any issues and can definitely tell the difference in performance by the time I return.

Thanks for the reply and information. All this fuss over emissions is stupid. Big oil can make a cleaner burning fuel, they are just to greedy and don't want to spend the money and just raking in on trash fuel that cost them little to make.

and what different in performance are you seeing?

i've found that while Renewable Diesel doesn't fill up the DPF as fast, it also provides less power and lower fuel economy than a good Petro-D (usually with BioD).

Since I run renewable majority of the time, I notice it the most after returning home from out of state on trips longer than a week or more. Seems to not be working as hard. More pep in lower gears. Even noise level a little bit. Almost feeling like the difference between driving with a tailwind versus a headwind. Mileage wise, I would say a little bit better but that’s not the primary benefit I see. When I drive to SoCal, I generally get better mileage going south with the Propel then when I’m returning north after running through a couple tanks of regular diesel. I also notice that when I change the FF after driving mostly near home, the filter isn’t as dark or smelly as it is when I have more miles with the non-renewable fuel.

Exactly, a quality fuel. May cost more but worth it. Like E85, a better fuel, burns cleaner and cooler and you get better performance. Downfall of it is lower mpg but the benefits out weight all the rest if you ask me. I wish Propel was over here on the east coast.

I just ordered some Archoil as well and will be switching over from EDT after watching that video.

I think I'm just going to keep running Marvel Mystery Oil until someone does a study saying that it's trash... At which point I'll keep running it anyways because it's been working for me so far!

Hey, at minimum it smells delicious! ;) :fist bump:
In the fuel? If it has mineral metallic compounds, it can make ash which will build up in the DPF.

I'm guessing you missed this post?

@GladiatorPilot23 all diesel fuel additives are worthless. The only thing you need is biodiesel fuel. I guess if you don't have any near you, then you can use some of the other fuel additives. 🤷‍♂️

But they'll never be as good as biodiesel fuel!

:like: You're welcome! ;)

Arcoil is great but one issue is that notice the HIGH level of iron in it. That is because it has a iron based fuel borne catalyst (FBC). It will burn soot down at a lower temp but it also will create ash which will build up in the DPF. With simi turcks and industrial applications. The DPF is eastly removable with a V band clamp. so if they use a FBC it is easy to clean but still get the benefit.

The best Diesel is Renewable which is not the same as Biodiesel. Propel is Renewable and you will love it once you try it! High cetane and much less soot. A little quarter. 76 also sells there own Renewable since they own a Renewable refinery. If you use the Fuel forward app from them, you get 30 cents off each gallon. I use gas buddy to find the best price along my drives.
