The EGR and DPF have no dependance on fuel lubricity. Removing them has zero effect on the fuel system's lubrication or fuel type needs.

Actually, thats not a fact, thats an opinion. An anecdote at best if we completely ignore the Scientific Method.

Not physically possible. A few oz of oil does not have any measurable contribution to the BTU of the fuel (and please don't try to claim that "catalyst effect" BS). Its purely psychological. Your actions caused you to have an increased awareness which leads you to credit any changes, no matter what caused them, to what you did.
Its the same effect people see when they replace the stock cold air intake with some louder aftermarket junk, the increase in noise causes them to believe there was an increase in power when there was really no change at all.

On top of that, 4,000miles is nothing. My fuel economy goes up and down several mpg every tank. Something as meager as a few days of rain can make a whole MPG change from the increased rolling resistance. Come back when you have 40,000miles of numbers so they can be averaged together for a more reliable data figure.

 

correct, the DPF and EGR have nothing to do with fuel lubricity... but the burning of the oil can potentially plug up the DPF faster, which in turn requires the truck to regen more often to burn it off, and what does the truck use to regen? yep... diesel... injected into the cylinder while the exhaust valves are still open so the temps rise enough to cause the burn off.

as far as fact or opinion, sorry bud, but it is FACT i have ran the oil in my truck. i can FACTUALLY state that as i poured it in with my own two hands. that my friend is fact.

as far as mileage, that is totally your opinion. i do understand the concept of the human mind piecing things together to make up a solution that is feasible to the brain even if it has to alter a few facts to make it fit better into the scheme the brain is trying to pass off, but i dont foresee this taking place on fuel mileage. i set cruise control at 65 and make the EXACT same 80 mile trip every morning and night... your saying that my cruise control has built a mind of its own and it is psychologically tricking itself into thinking it is getting better mileage?

again if you read my last post, actually the last sentence... you will see my disclaimer....

 

linked I agree with whargoul your running some special additive in your truck for 4,000 miles is like I ate fruity pebbles this morning instead of grapenuts and I wasn't tired at 2 in the afternoon so fruity pebbles must give you more energy. Like he said run it for 40,000 or 50,000 miles then come back with the numbers and we can talk. Untill then I will continue using my good old unicorn horn powder to help with my mpg.

 

right on man! let me know where i can get some of that unicorn powder too man! ill mix that at 200:1 ratio with the oil before i add it to my tank. i have yet to stop running it and i will continue to run it. ill let you know when i pass that 40k mark with oil and continue on.

 

If a few oz of any of those additives actually did anything beneficial, fuel companies would be adding them to the fuel from the start and advertizing their inclusion.

Just like if pyrometers,boost gauges, and mud tires were beneficial the manufacturers would include those from the factory too. Your truck's all stock, right?

 

 

im with linked on this one my truck does seem to do a little better with it maybe by coincidence?? i dunno but all im saying its not going to hurt anything but put some extra lube through things which isnt going to hurt nothing

 

Nothing wrong with more Lube.

 

Like a boost gauge, 2-stroke oil will only make you feel better psychologically.


so your saying 2 stroke wont do nothing at all for anything

 

(corrected)
Correct. A 200:1 ratio like linked said he uses does absolutely nothing.
He would have to use under 50:1 before any measurable benefit would occur. Long before that point, B2 or B5 biodiesel becomes the cheaper option and they will both lubricate far better.

For a 35 gallon tank, that means he needs to add at least 3qts of 2-stroke oil per tank before there would be any measurable (non-psychological) benefit.
That would be, if 2-stroke oil actually blended correctly with diesel (it doesn't).
