To add Power Service or not?

[some zilch]

Not.

If you ARE a non air breathing life form I would appreciate it if you take it seriously for those of us who DO breathe air.

wow, i'm going to use twice as much now seriously.....you should see the way my detroit diesel powered generator runs on straight waste oil.....no mosquitoes near me


PS does make a difference, i can tell the way my early 90s cummins run when PS is in the tank and when it is not. the engine does run a bit smoother and less "rattlier". ULSD is not great stuff, in my opinion. the old diesel is better. ULSD is an emission gimmick, and i dont care what anyone else tells me. i can see this new fuel eating my o-rings and seals in my older injection pumps, because the lubricity is not there.

I do not use Power Service any nor would I ever again..If you test your oil you will see. Then again I only get to -20F and it is fine..

The most famous quote I ever heard regarding sulphur was from someone who worked on a refinery. Refiners have had processes for years which have been capable of removing almost all the sulphur. The fact is that sulphur is a natural byproduct of refining crude or gassified coal. Refiners seperate the copious amouts of sulphur in the feedstock and sell it as a seperate line item. (where do you think the battery makers get their sulphur to make battery acid ?)

Here is the rub: The refiners can sell the sulphur on the international market for $130/ton (about 50c/gal) or they can dose fuel with it and get between $2.50 to $5.00/gal for the exact same stuff. Now what do you think they are going to do ?

The fact is that most of the western world except the USA and Russia (superpowers, right ?) have long since reduced sulphur in diesel fuel to the levels only recently mandated by the EPA. Sulphur is one of the primary elements that poisons catalytic converters and drives up the worldwide demand for platinum and paladium. Turns out that the places that these materials are found are not the friendliest in the world, same as the present situation with crude and natural gas.

I personally worked on the construction of a natural gas to synthetic fuel refinery that due to the feed had virtually no sulphur and it was the largest producer of clean diesel fuel in the southern hemisphere. There was a time when the government had to order the refinery to sell more of the clean diesel on the local market, since they could get a premium price for the clean diesel in Europe (and foreign exchange). Now Europe gets a substantial amount of their diesel from rapeseed (biodiesel) so the demand has eased.

The automotive industry has lied and lied and lied about the reasons for not changing the status quo. Thielert took a 90hp mercedes automotive diesel engine and modified it to run on Jet fuel for certified aircraft applications. Basically the engine runs on kerosene and still uses a high pressure common rail fueling system that I would vouch runs at double the line pressure of our local diesel pickups.

And here I thought the black helicopters didn't fly on Sundays. Darn, where did I put my tinfoil hat?

No need for them to lie about anything.
Straightforward enough; established practice, status quo, existing designs, same old same old,,,, are just about ALWAYS the cheapest route.

New designs every year ?
Nope, slight changes in sheet metal, moving the model emblems up/down the size range to create the illusion of producing "smaller and more efficient" or "bigger and better" is the same old set of tricks.
No re-design about it, re-badge'ing is about all.

DuPont/GM's Lead in gasoline scam, or closer to THIS point - STP in engine oil, SURE your engine NEEDED IT (-:

At the end of the day; would anyone WANT TO still be driving a 73 Torino ANYWAY ?

Just so you know, PS goes in your fuel tank, not your glass.

Power Service is ULS compatible. Used it in my 500 h.p. Cat. This is what I found....very little mileage gain, no extra "peak" power, but a whole lot more throttle response allowing it to hang on and accelerate back up quicker. Never had moisture problems in the winter either.
If you can find Caterpillar fuel conditioner it is 10 times better as far as performance improvement.
As far as in a compact tractor....I'd save my money and buy atf....cheaper and keeps the injectors clean and working.

Not in my tank, or my glass.
Your choice of "additives" is of no interest to me, or where you put them.

Yes it is true that refineries removed sulfur from the feed but to remove the last small amount they had to build so called hydrotreeter process. That required quite large investment to get very little sulfur. In other words they would never build it without legislation of ULSD.
To modify automobile diesel to run on jet fuel requires almost no change in the engine. To make it an aircraft certified engine does require significant change regardless of fuel used. The aircraft Thielert engine cost more than average CUT.
Yes sulfur has lubricating properties but I think the effect is way overrated. Four stroke gasoline engines run without sulfur and lubricant added with no ill effects. I also heard that some (or all) refineries add biodiesel (oil) to enhance lubrication properties of the fuel (or the motivation is some kind of tax break).
Common rail fuel injection is the latest iteration of the diesel fuel injection system. The advantage is that the injection is controlled by solenoid valves that are controlled by electronics. So the injection timing is controlled (mapped) based on rpm, power demand, temperature etc similar way as in gasoline engine. Such engines have about the same rpm range as gasoline engines. That was not economically possible with mechanical injection.
