Anyway fired the car up from cold and the engine is a lot quieter.

Yeh but my car's emissions aren't that important due to it's age. It's the newer ones that need have their cats and dpf's etc.
I also fine tune things though so as not to smoke like a tyre on fire. Even with my bigger nozzles i don't get loads of smoke if any.
A lot of the newer cars get really cheap road tax based on the emissions but not me, I pay full price.

Yeah I paid through the nose too when I lived there and ran my Ford Escort 1.8D van.

I've given some thought to precombustion deposits from adding oil/2 stroke. My conclusion is that 2 stroke at least is designed as a precombustion lubricant since it is normally mixed with petrol/gasoline, If it was going to stick I think it would stick a carburettor before it would stick a high pressure diesel fuel injector.

I have been doing this for many years, and hundreds of thousands of miles on this engine, also at Herm's recommendation.

I still have the original cat and the original injection pump, although I did reseal the QA seal at around 386K. Even with the original cat, my B4 moves very well down the road, as anyone who has driven it can attest.

Here are some pictures of when I took the head off it at 393K to replace a blown head gasket (due to a failed water pump) and of the IP at 386K. There was no wear lip at the top of the cylinder and you could still read the original writing on the pistons.

I'm a believer and add 14 oz of 2-cycle oil (Wal-Mart asheless TC-W3) and 7 oz of either Power Service gray or white bottle (depending on the time of year) at every fillup (I have a 21 oz bottle and mix if before fueling), which is usually 16-18 gallons. I do this will all the B4's we have and they run great.

Like Abacus I run 2-stroke mixed with power service, about 3:1. Both our diesels get the additive.

The ashless 2-cycle oil is (in my opinion) an effective lubrisity additive.
The often over looked issue is lower aromatics (ULSD) thus affecting seal performance (shrinkage).

The wear Scar lubrisity test is a valid scale to measure different products in relation to lubricity. None of the products listed address aromatics and that is where adding an actual OIL to the fuel helps with improved aromatics.


Adding the 2-cycle oil will improve the aromatic content of your fuel. This is one of the reasons to use 2-cycle oil at every fill up.
Lubricate your pump and engine top end and it also helps to keep seals and fuel lines from shringage and becoming brittle (leaking).

I run ashless 2-cycle oil in every diesel I've owned...even my generator is diesel.

CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.

I've been running this mixture in my powerstroke for the last 4 yrs...

1 oz marine ashless syn 2 cycle oil (walmart tc-3)
4 oz powerservice

have it mixed up in old stanadyne 12 oz plastic bottles....add one b/4 filling up

no issues...

I may start in my JSW but for right now I run powerservice and a qt of B-80 in a mixture...
