So the Lake Speed Jr. and Repair Geek just posted a video testing 5 different diesel fuel additives against untreated fuel. Interesting results with Cetane and wear scar. If you don't want to watch the whole video just go to time stamp 23:43 to look at the results. That said there is a lot of good info throughout the entire video.

Interesting that 2 out of the 5 had potassium in the recipe and one had a butt load of iron.
No Amsoil?
45 minutes plus video thanks for the skip
yeah thanks good ingredients cost money

I would have liked to see Amsoil but Andrew stated the testing was $800 per sample so I can see why they didn't do more products.
Yeah truly a chunk of change
My comment was before the cost parts. Twas interesting! Good stuff just can’t be on my erse 45 minutes so I am cleaning the dishwasher while watching and listening on the big tv
I routinely use Power Service in white and grey bottle. Have for years.
Recently, someone told me about a cleaner from Liquimoly (https://www.amazon.com/dp/B00CPL8OVE?ref=fed_asin_title&th=1) that I am going to use as a preventative thing, in an old "real" diesel engine.
Never heard of XPD. Pretty expensive.
I think I will stick with what has worked well for me, Power Service
@Pablo what about Amsoil?

Diesel fuel additives are a very complex series of topics. In no specific order, these are the topics which might be addressed by any brand product. The products can be either singular in approach, or a multi-tier approach:
- cold weather flow
- lubricity
- cetane improvement
- detergency
- fuel stability
- biocide agents
I use the white bottle FPS (technically their winter formula, but can be used all year long); it has a little less cetane boost, but adds the all-weather ability by suppressing the wax cloud point. I've used it for years, and been very pleased. I think there will always be a product that might outpace it in one category or another, but when you look at all the topics I listed above, the PowerService white bottle address most all of them and does so in a positive manner. It's one of the better "all around" products, IMO.
I wanted to understand the underlying chemistry in the PowerService various products and so I called their tech line. They put me in touch with a chemist who took the time (almost an hour on the phone) to explain all the whys and wherefores to me. That alone made a lifelong consumer out of me. I'm not saying that other brands aren't good; they probably are. But PowerService does make a very good product and they took the time to help the consumer understand the choices to make; that was the tipping point for me.

I saw that this AM. Different goal additives.

Don't forget the project farm one armed bandit!
Hey man I made it through his terrible screetchie voice. He's an odd duck. All of a sudden he's testing Amsoil 2 stroke race oil? The heck??Don't forget the project farm one armed bandit!
I will say I've never seen a recovery type product in use. Basically the few that worked, only worked with double dose+. But even weird he threw yet another kind of product in the mix.
I wonder why they only worked with x2 the dose, that seems weird to me.
He did his wear scar test. Whether it's valid... But there was some overlap with the lab tests with brands.
When you think about it, a large mass - 30-50+ gallons - of gelled diesel fuel adding a few ounces, of much anything, not going to do the job.
I would add a few warm bottles let it sit then fill the tank up with the best, driest, warmest diesel that one could find.

See above. I was referring to the types, the goals, the expected roll of each product. One guy tested some additives, the other guy tested anti-gel and recovery additives.
Got it now, I see the Amsoil he chose was the Cold Flow which isn't a cetane booster. And of the brands that overlap 4/5 of the PF products claim to boost cetane except Stanadyne.
PF was planning on doing the wear test, pretty idiotic he didn't use the All-In-One
I guess he was only doing wear tests because of claims???? Wear tests seem silly for a cold flow diesel additive.
Really the only diesel additive from Amsoil that I would expect a little wear protection is the injector cleaner.
If you are really wanting wear protection put some concentrated 2 stroke OPE oil like Saber (not race oil) in the tank.
