Diesel Additives

[HEMIMANN]

I do believe they can go over the 20% +/- but not under, I do not think they is an easy way to not go over if they must be at a minimum of 20% so error on going over 20% an not under that could get them a big fine

Which is exactly what engine makers do NOT want!!!

It wasn't long ago Cummins would only accept B5, and begrudgedly accepted B10. Bio wears out engines faster from deposits, but has good lubricity.

Point is, I spike all diesel fuel with additive here, and only buy enough fuel for what I burn in a week. The best government corporate money can buy-off.

I was told that 5% bio increased Cetane, I never took the time to find out if true as I stayed away from it when I lived in IA due to gelling factor and then only use it now because I moved to a state that mandated its usage, 5% bio for me that means I have to keep anti gel additives on hand no less than 5 months of the year because gas stations in the greater PDX area don't know how to winterize diesel...

I have a 1998 6.5TD and I run regular 2-stroke oil for the missing lubricity in the ULSD even in the winter. The truck has never been garaged and never plugged in. I do have and have used Power Service summer and winter formulas on occasion. Nearing 200K on the odometer and with the exception of the injection pump covered under warranty, never an injector failure.

2007 and older diesel can run Bio without major problems, its the newer engines that have problems with B-6 and above.

Endorsed by Cummins =Powerservice Diesel Klaan should be in every Cummins?

With EGR coolers, DPF, def, catalytics, forced air, I'd be putting anything in there I could to avoid clogs.

All of these additives do nothing for your truck. Other than anti-gel stuff in extremely cold climates they all all unnecessary.
While the probably don't do any harm they have no benefit other that fixing perceived shortcomings in our fuel.
People use them and swear they work only because the BELIEVE they work.

I've been puzzled why my 13 year old Yanmar Diesel started clogging fuel filters rapidly the past few years.

Then I found this article, and remembered the Minnesota Legislature was bribed by the Agri Industry Giants to MANDATE B20 (minimum) Biodiesel, NO EXCEPTIONS, a few years back. Fuchers....

I should have put 2 + 2 together. Tractor fuel filter started clogging quickly just when Minnesota mandated B20 biodiesel everywhere.

Damn crooked legislators!

Calling all you diesel gurus out there, esp. those long in the tooth.

I've run my little Yanmar diesel over 2,000 hours in my Deere Tractor. Most of the load is high with mulching mower deck @ rated rpm = 3,200. Best case operating conditions for it. Generally accepted it's an 8,000 hour life engine.

I did the fuel injector "service" this spring (cleaning and resetting pintle pop pressure),, new glow plugs and harness, new breather valve, etc., and still getting some white smoke @ startup. Otherwise runs fine.

We all know white smoke means unburned diesel fuel or coolant leak, it doesn't use any coolant. This is an old-timey IDI engine, with a Yanmar Inline 3 cam fuel injection pump. Think: EPA Tier 2 Diesel Nonroad Emissions Regulations <2013.

And so - I'm assuming the precombustion chamber, orifice, and cylinder are carboned and need cleaning. Do any in-use cleaners work, or do you have to do a minor overhaul? I've read of Hot Shot's Secret Extreme Diesel Cleaner and

Is it ambient temp dependent? Cold smoke was not unusual with Yanmar stuff when I was a Deere dealer. I had a New Holland 2120 with Shibaura engine that smoked pretty good when cold.

No, I forgot to include that.

If the engine has not been run, it emits a puff of white smoke and a stutter. Restarting hot engine doesn't.

It never really gets cold it is in my shop in winter which I keep @ 45 degrees F.
For the 1st 1,500 hours or so, it never smoked or hesitated starting. Ever. So all I can think of is carbon buildup in the orifice between pre and main combustion chambers, and maybe piston crown carbon deposits. Maybe rings too, Idk. Doesn't act like stuck rings cause it runs fine.

Interesting. I have seen Yanmar engines with way more hours that were rode hard and put away wet, and didn't have pre-chamber issues. Never saw a ring issue. My first thought would have been a drippy injector. Their pumps, inline and rotary, were pretty trouble free. Also, have you tried checking valve lash?

Yep. Adjusted @ 1200 hours, only out app. 4 thousandths. Checked @ injector service 2000 hours hadn't worn at all.
Strike 2.

Did the engines you saw have forced $hit bio fuel.

 

[Grams]

Freedom Worx, Project Farm, and Lake Speed….. Each have run diesel-additive tests and videos…. and some of the better known additives have Some Benefits…. But there is only ONE they ALL agree on being the best: Hot Shot Secret EVery Day Treatment (EDT). Some of the “best known” products are actually quite poor, and two very popular ones Surprisingly failed to do what they claim, or fail to do so as well as Hot Shot EDT (Stanadyne and Archoil were surprising stand-out poor performers.)

I’m usually critical of snake-oils …. but if I ever use anything at all other than a biocide (Biobor JF) it’ll be Hot Shot EDT.

No, bio was not a thing(at least in my area), late 80s to mid 90s. Deere went from the 50 Series to 70 Series gear drive compacts while we were involved. Large utilities were still the 55 Series, not to be confused with the 55 Series compact hydros.

Other then the gelling issue I have not had any problems with bio-diesel. It will plug fuel filters on engines with dirty fuel systems because it acts as a cleaner.
In my tractors I will blend my fuel #1 and #2 depending on the weather forecast. My truck may get some on an as needed basis.
I also run anti-gell additives at the winter rate from fall to late spring, or when ever my treated blended bulk tank runs out.

You can try the new Power Service Injector & DPF flush, they claim it will clean up the whole system in one tank, you should be able to find it a Wally, TSC or Amazon, my self I use Archoil 6400 D system cleaner, Power Service is not all that costly at $17.00 where Archoil 6400D is $25 on Amazon. Here is a link to PS new additive: https://powerservice.com/diesel-injector-dpf-flush-is-here/

You gotta love Todd. When he first came on the scene, he received a fair amount of pushback on his "non-scientific testing". I don't see that anymore. Before I buy, I will search his video archive to see if he tested the claims.

 

[tjfdesmo]

I have been seeing more frequent regens, for no good reason, on my '24 Cummins, and tried the new Power Service Diesel Flush for 100 gallons worth of fuel. It had 0.00 impact, as expected. Same with the much ballyhooed Archoil. Save your money IMHO.

Except I have a good reason @ 2,000 hours and changed engine starting behavior, as per my O.P.

There are certainly worse things to spend money on. Have you ohmed out your glow plugs?

Better - we tested them on glow plug cycle - positive for voltage and amps. I replaced glow plugs, wiring harness, and relay. The glow plugs work. The injectors are clean.
