I agree.

 

That may very well be. (have an effect)

Direct injection [diesel] engines produce a rather unique noise upon ignition. Newer engines reduce this "noise" by carefully controlling the ignition event even breaking up the event with possibly several "events".

Using 2-stroke oil *just* for perceived lubricity "benefits" without considering all the other benefits (or detriments) might not be good.

No one (ASTM, SAE) has ever tested for possible deposits that might result from it's use in a compression ignition engine.

Here's the specification for diesel fuels by the way. once you download the PDF, scroll down and read through the "tests" that diesel fuel has to pass before being "approved".
<cite class="_Ad">https://law.resource.org/pub/us/cfr/ibr/003/astm.d975.2007.pdf</cite>

If any company did successfully test diesel mixed with NMMA TC-W3 oil, the outboard motor oil manufacturers would absolutely want to increase their profits by selling it to the entire diesel fleet! (2-stroke engines are decreasing in numbers world-wide......) NMMA - TC-W3® TWO STROKE OIL CERTIFICATION PROGRAM

[That lubricity test several years ago by the way that WAS conducted by a reputable lab ONLY tested for lubricity. They did not test for all the other diesel fuel parameters]

I know the manufacturers "say" "Ash-less" but that's ash-less when mixed with gasoline and burned in a 2-stroke gasoline engine.

The combustion parameters in a diesel are very different. (which is one reason there's so much more NOx in diesel exhaust compared to gasoline engine exhaust)


I am not trying to talk anyone out of running it in their diesel.

I will say that if you have a new diesel that is still in warranty, or a "warrenteed" fuel system, and you're running ANYTHING (not approved) in the fuel AND you have a fuel system related failure............

FORD/GM/Chrysler may discover it and try to deny a warranty claim. They may still approve the claim too.......but it gives them an "out". The first thing they do in any fuel system problem is "test" the fuel for "contaminants"

So dumping anything in my fuel (or oil) just because:

1. Everyone else is doing it and "they haven't had a problem"
2. It might make me "feel" better.
3. Some additive manufacture [seller] claims it's great
4 Testamonials (see below)

Might not be the best reasons..........

I feel just fine using just reg'lr diesel fuel...............

supposedly the biggest problem with USA fuels are that they are junk! The european standard is higher reference a clean fuel and the flashpoint is hotter. This was in an article some time back on the problems faced by the 6.0. Fuel quality was compared and it was determined to be lacking for such a complicated and fine tuned engine and that was one of the factors found in the 6.0 and some of its related problems. Read this in one of the truck mags when the engine problems first started to pop up. Diesel world or power may even have been a truck trend article.

 

Hard to say what a magazine article writer means when he says "clean".....They're not engineers and a lot of them get what they write wrong.

Flashpoint is not a property that is a big deal in direction injection engines that produce 20,000+ psi injection pressures.....

Here's a comparison of major properties D-975 vs the European EN590 standard.

If you want to talk just "Clean", note that the total contamination is higher but more important the total water and sediment for EN590 is astronomically higher!

I'd say that (at least standards-wise) European fuels are NOT "cleaner"

Lubricity is a tad better, But if you notice the last item (fatty acid.....) EN590 requires a min % of bio-diesel which if added, increases lubricity. D-975 doesn't require as much bio-diesel to be added[yet] for approval. (that's a political thang possibly)

Cetane is a little higher (but cetane is not the bee-all/end-all of diesel fuel)

Sulfer is much lower. (possibly also why they're adding bio to increase lubricity)

So in a nutshell, I am not seeing where European diesel is "better" than D-975 diesel.










Let me also add the link to the actual test that everyone quotes on diesel fuel lubricity..........

http://www.jatonkam35s.com/DeuceTech...itive_test.pdf

If you're REALLY worried about diesel fuel lubricity, you'll want to buy Biodiesel (B100 if you can find it) and add it to your fuel [2%]

If B100 is not available, you'll need to add more to get the desired effect.

Otherwise, use the second or third choice in the list above. It's interesting to note that Supertech TC-W3 outboard motor oil did BETTER than both Stanadyne Performance Formula and Power Service Diesel Kleen! [maybe my 6.5L IP wouldn't have failed if had used TC-W3 instead of SPF!!!]

I hope no one here is foolish enough to use Marvel Mystery Oil! It performed worse than running used motor oil! [according to the NTSB it's Stoddard Solvent, mineral oil and lard!]


I was pretty bored today so I searched through SAE website for any published papers for key words including "HFRR DIESEL FUEL TC-W3 2-Stroke " and found no paper on this. Evidently these guys did not publish this data.

I also couldn't find any other paper (published in the SAE database) that mentioned using TC-W3 as a fuel additive. I suspect that that they would "shut it down" since it wouldn't be ULSD compliant.


Anyone else tired of this stuff?
