Adding 2 stroke oil to fuel - Interesting reading!!

[CardinalSin]

Take it from a few fellas that have cut open DPF casings for whatever reason - DPF equipped engines produce plenty of smoke and the DPF really works.

FWIW, i see plenty of new diesels (non dpf equipped) that smoke plenty too. It might not be obvious to the guy driving, but its there. New ford territory's and Range-rover sport diesels, I'm looking at you

I'm sure the DPF works well it's just that it must be starting from a low soot level or it couldn't cope and would be doing a regen every day. Some of the trucks that, thankfully, are very rare these days, would have filled it up in between gears.

True, you can't see it unless it's over a certain level but I do ask anyone I know that has followed me if it's clean back there.

Those Range Rovers do pump it out!

DPF offshoot: A lot depends on how you drive it - tramping on the right pedal at low rpm will smoke big time while at higher rpm, when the turbo is pumping lots of air into the combustion chamber, the same action will produce far less (if any) smoke.

Maybe we should get this discussion split into its own thread
It seems less relevant to 2 stroke oil use than 2 stroke oil discussion was in the additive thread

An 'a' and 'b' breakup of a single thread would remove a lot of confusion maybe.
Prob not pos.

Here's an interesting post with some technical info and pics to compare injectors after using 2SO.

2 stroke oil in diesel...anyone tried it? - Page 6

"Here's a pic of injectors pulled from a year 2003 Y25DT Opel diesel 110 KW engine (identical to BMW M57 engine).

Compared to injector No2 (80000 km total, therof 5000 km of usage with 2-stroke oil) injector No1 (120000 km total, thereof 40000 km of usage with 2-stroke oil) shows very little signs of deposits.

Below shown is an injector that has never seen any diesel fuel refined with 2-Stroke oil of type API TC + ISO L-EGC + JASO FC

Some pics of evaporation tests performed by a knowledgeable member of the Motortalk-forum showing the relative degree of carbon/sulfur content of different 2-stroke oils:


















This seems to be one of the least expensive UK suppliers of the recommended type oil:

BTW the results of TÜV / MOT emission tests for diesels, especially the soot measurement, are noticeably better when using the 2-stroke oil continuously - with or without having a particle filter installed.

Those injectors pictures pretty much mirror the ones shown on the Freelander2 thread by one of the South African posters. Nice to have another confirmation of the cleaning effect of 2 stroke oil.

Too bad that one of the more recent posters in the a2 thread has no idea of the difference in dilution (and air:fuel ratio) for 2 stroke oil use in diesels vs his previous experience with 2 stroke petrol engines.

Now that this thread has been reopened, should the other one be merged back in?
