Diesel engine additives test

[SnottyW]

This is really informative:

In this video we are going to take a look at 5 popular diesel fuel supplements on the market: Stanadyne Performance Formula, Hot Shot Secret Everyday Diesel Treatment, PowerService Kleen + Cetane Boost, Archoil AR6500, and Opti Lube XDP All-in-one.

All of these products are marketed to improve the lubricity and cetane of your diesel fuel. We are going to compare each product to untreated diesel fuel to see if these products do what they claim to improve diesel fuel. Each sample was tested using D6079 otherwise known as the HFRR test and D613 which tests the Cetane of the fuel.

Two of the largest issues going on right now with light duty diesels are high pressure fuel pump failures like the Bosch CP4 and emissions system problems. All of these products are marketed to improve the lubricity of the fuel which would help keep the CP4 pumps alive and increase cetane which helps the fuel to burn cleaner, reducing soot build up in the engine overall.

Great video. Its nice to see some actual tests from these products. Makes me feel much better about spending the money on them.
I have been using EDT but just received my package of Archoil and will be transitioning to that when i run out of EDT. Will be interesting to see if i notice any improvements.

How would you notice the improvements?

Performance with the higher cetane rating, possibly a smoother running or quieter engine would be my guess. I'm doubtful it will be substantial.

A buddy of mine turned me on to Archoil when i bought my first F350 7.3 Powerstroke. Still use it today in my Ram 2500 CTD. It works

I'm on my first archoil treatment and I'm seeing a difference in how fast my dpf fills with soot.

I'm lowering dpf% driving around town with archoil.

Solid find, thanks for sharing. 46 min long...oof. Here's the segment where they actually get into results. FF to the end to see the final table.

TL;DR: XPD All in One had the least wear, then Archoil AR6500, then PowerService DieselKleen+, followed by Hot Shots EDT and lastly Stanadyne PF. After this, cost per treatment is reviewed.

I watched that today too and immediately ordered the XPD all in one.

I’ve been using Hot Shots EDT and seeing single digit potassium numbers in my used oil analysis.

I was worried I had a slow coolant leak but hoping it was the fuel additive. Finding information about their chemical makeup is impossible so the timing on that was great.

 

[rarefied.air]

Now, I will say, this is a one of one sample. I'd like to see the variance across these tests per product, but that would require many more samples run. Are they, statistically, significantly different? I'd imagine there would be some convergence here on product.

Couple more interesting notes:
-Look at that Valero ULSD they picked up. Cetane of 57.6, wow. > ASTM D975 sets a min of 40.
A tangent to this analysis would be who has the best diesel, in terms of lubricity/additive package and cetane. Variance INTENSIFIES....
-Does anyone use XPD All in One? Haven't seen a lot of takes on that in the forum.
-The IR analysis at the beginning to show differences in makeup was a bit of a gloss over for me...just pull the SDS.

The one thing I couldn't stand in this vid, Repair Geek constantly kept pronouncing cetane wrong. He kept saying c-a-tane, when its c-tane. Great vid otherwise.

Jesus Christ man, 46 minutes with an outcome that I can probably guess without doing any research whatsoever:

Some brands are better than other brands, some brands are significantly better than other brands, but at the end of the day, anything is better than nothing. If it lubricates, it's good enough for the EcoDiesel.

Damn, I just saved 45 minutes by using a little bit of common sense!

Personally I use Marvel Mystery Oil. They say it's not meant for diesels, but the days of 2000 PPM sulfur in your diesel fuel are long gone. Sulfur is good for diesel engines, may not be good for the environment, but it's great for your diesel engine! Marvel Mystery Oil will take your 15 PPM sulfur diesel fuel you get from the pump, and it will up it all the way up to the evil amount of 16 PPM... I know, crazy right!?

I don't know how much most you guys actually know about why most of us EcoDiesel owners use fuel additives, and how many of you are just doing it because everyone's telling you you should, but the only reason you should be using a fuel additive in your EcoDiesel is because of the BOSCH CP4.2 HPFP.

Don't matter if you have a recall-completed Bosch CP4.2 or if you have the original one that came on your Jeep, if you have a CP4.2 on your Wrangler, you should be doing the smart thing and using a fuel lubricant to aid in the possibility that you get a void situation and your Bosch CP4.2 doesn't grenade your entire engine.

In that sense, any diesel additive lubricant works. Don't matter if it has more potassium, or less ash, or more this and that, or more whatever, if it lubricates it's good enough for your EcoDiesel!

In the situation where any of us were to get a actual fix for the Bosch CP4.2 HPFP, and were to install something such as the RCD CPX, then in reality, adding fuel additives after that would simply be FEAR INSURANCE, You wouldn't actually need any fuel additives assuming you are driving lots of highway miles as you should be if you purchased an EcoDiesel to begin with, and you're getting regular regens.

So that being said, y'all should do yourselves a favor, save some money, stop buying those overpriced nonsensical extra BS fuel additives, and get you some Marvel Mystery Oil. 1 gallon for $22 bucks, and the limited assurance that your Bosch CP4.2 might not brick your whole engine if it does hit a void scenario.

Are you sure "this offering" @Rhinebeck01 didn't help with this sales pitch? Hell, the name "Marvel Mystery Oil" doesn't have any similarity to "Snake Oil" whatsoever! Buy it today!

Somehow they neglected to test your "obviously not Snake Oil" "Mystery Oil", but if you had watched the video you'd have seen that one of them was not better than nothing. The wear scars were actually worse than not adding anything. Fortunately not significantly worse though. The suckers that bought that one for the life of their diesel thinking it was lubricating their fuel pumps, however, wasted thousands of dollars.

So yes, watch the video so you can make an educated decision on which makes the most sense for your situation. He summarizes it all near the end. No, the testing methodology isn't perfect, but nothing is.

Oh ye of little faith!



Here's the breakdown of what's in Marvel Mystery Oil:

On a related note, I noticed they didn't test any AmSoil additives in OP's video. How convenient!

 

[BDinTX]

FYI potassium in a fuel additive inevitably finds its way into the motor oil. There it can mask a real problem - a coolant leak.

On top of that, when burned it reduces the life of the catalytic converter by “poisoning” the reactive metals. Obviously only a concern for those of us that kept emissions equipment installed.

People used to change their motor oil and pour the old stuff back into their fuel tank. What used to be safe for diesel motors may not be anymore.

I used EDT and Diesel Kleen on my deleted ram 2500 for years, made a noticeable power difference (cetane increase) when i used it, and it would also stop surging.
