TCW3 in Diesel

I'm looking for peoples experiences with running TCW3 in diesels? Specifically more modern direct injection diesels that are emissions strangled.

I've had previous experience of running 2T oil in diesels but it was an old Peugeot XUD9TE with indirect injection and an old Bosch VP44 fuel pump. It was run on vegetable oil and 2T oil added at 500:1 used to quieten the engine down quite a lot. I would usually use the cheapest 'mineral' oil I could pick up knowing nothing about oil specifications back then.

I currently have a modern common rail diesel with a DPF, EGR and SCR. I mainly use BP Ultimate or Shell V-Power diesel, but if unavailable I use standard branded diesel with Archoil 6900-DMax.

I'm thinking of giving some TWC3 a try with some standard fuel. Just wondering if anyone had any experiences or advice? What oil was it and what ratio did you try?
 
I sent out samples of fuel (Kerosene for use in a diesel gen) treated with Pennzoil semi-syn TCW3 and some with Stanadyne lubricity additive (and both) for HFRR testing. Clearly, the TCW3 improved lubricity and reduced the wear scar (test results) far more than the Stanadyne.

While that does not specifically answer your question, you should know that at 100 to 1, the 2 stroke oil was passing through the catalytic converter, unburned and dripping significantly from the exhaust on one of my engines.

In the end, I chose 200 to 1, and the recommended amount of Stanadyne. The engine still uses this mixture, without any fuel system issues.
 
I have no experience with tcw3 in diesel, but I used in my old cargo van , it was once ounce of tcw3 to 5 gallons of gas,,,,I could not tell it did anything.. look up Been testing oil

My brother-in-law runs some in the fuel on his duramax. His truck is deleted, and he had a fuel lift pump fail and ruin the entire fuel system on the truck, he's hoping that the tcw3 will help his new pump live longer.
 
Thanks guy's. I think I'll grab a litre and give it a try. Maybe at 1000:1 to start with and maybe head down to 500:1 over time.

If I have time I may even try borescope the piston tops before and after.
 
Common diesel engines are made for ULSD so there is no need to add anything to the fuel for lubricity. I think you will do more harm than good on an emissions compliant engine like you have @Bailes1992

Just my $0.02

What kind of problems would you expect to see using a very small dose of an ashless lubricating oil in my heavy oil based fuel?

I’d be concerned about the possibility of impacting a sensor in the exhaust and the added contamination of the DPF. I agree it’s a low dose but the system is not designed for it.

did you proceed with the experiment?
I wonder how it did because I'm thinking about doing the same

I did not, although I'm still curious about it.

I run an additive with every tank as they make me feel like I'm doing some good. I must admit, I don't think I notice any actual difference in driveability or economy when running them.

Most 'every-tank' additives are much the same, some 2EHN mixed in with a lubricant of some sort and a solvent for cleaning. I usually alternate between the following...

- Millers Ecomax Diesel
- Archoil 6900-DMax
- Oilsyn Diesel Power DNA
- Mannol Ester Diesel (Although I'm rethinking my use of Mannol products as I keep hearing about some very dubious practices.)
- Stabil Diesel (Doesn't smell like 2EHN like the others, so don't think it contains a cetane improver. Smells heavily of Xylene.)

I did a lot of research and I'm thinking about a diesel ester blend that boosts the lubricity of the fuel system / upper ring liner wear performance.
keeps the injectors clean and reduces the formation of soot and fuel dilution I've seen a research where there was a noticeable visual difference of contamination around the injector nozzle
magic lol
i think the CME or CEE B2 blend will do the trick
i still need to do so much research
Mannol Ester Diesel seems interesting to me
 
FWIW: I had a VW tdi and always was a little worried about a $,$$$ fuel system failure... Thinking the ULSD would takes its toll post 100k. I kept a bottle of this and added like 1 oz to each tank. Can't remember what the ratio was. For 90k miles I can't say one way or another if it helped... did not hurt anything I was aware of... Sadly diesel gate triggered a VW buy-back I could not refuse and never found out exactly how long it would last.

  • Our most concentrated diesel product, popular for semis, agricultural and fleet tanks
  • Cleans and lubricates injectors, pumps and rings, improving efficiency up to 5%
  • One 15oz bottle treats 100 gallons/One gallon treats 850 gallons for a strong clean up dose
  • For regular maintenance, use one bottle to 300 gallons of diesel fuel

I've wanted to try this stuff for a little while. Unfortunately the bottle doesn't have an internal measuring/dosing container like the others.

However, I'm currently using Stabil Diesel which comes in a bottle that you can refill, so I may fill the bottle back up with Redline once the Stabil has run out.

Years ago, when sulfur levels were drastically reduced in diesel fuel in my area, I added 2-stroke oil at 1:200 to protect my older diesel fuel systems. I stopped doing it when biodiesel became available, as the "bio" restored the lowered sulfur's reduced lubricity.

Funny you mention that. My VW had this metal locking flap on the fuel cap (To prevent accidental filling with gas)... I had to buy a $20 plastic override thing to open the fuel filler... Bought a ~16 ounce translucent catsup bottle that had graduated markings on it... Dumped the Redline in that and made an guestimate how much got squeezed into the tank with each fill up. Not exactly scientific, but close enough I thought. (Miss the power and MPG of that car often)
