Stanadyne Fuel Treatment

[Dl5treez]

Where are you getting the info that Diesel in NYC is any different than in Calif?

Well I never said that. I said there is too much variance in diesel fuel across North America to make most determinations about additives causing fuel economy and power increases relevant unless there is a LOT of control built in. Some data to look at would be ASTM D975 which is the standard adopted by most of the US and N America for diesel fuels. Or ASTM D613 which sets standards for ULSD that conflicts. Or how the lubricity standards are inconsistent.

California and their min cetane of 53:

TEM’s call to action for improving the standards:

Boutique fuel programs across various states: Most of these relate to gasoline but some are for diesel fuel:

Texas in particular has rather complex network of county level adopted Low Emission Diesel standards that currently cover 110 counties:

https://www.tceq.texas.gov/airquality/mobilesource/txled/cleandiesel.html

There are more but that should keep you busy.

We haven’t even covered regional and local vendors and their own formulation of additive packages to make their own “premium diesel” which is a dog & pony show all its own.

That’s why I said it’s virtually irrelevant to compare individual results across the country.

Hope this helps

Keep in mind, there is nothing except speculation and anecdotes that fuel additives other than what is already in pump #2 will extend the life of a VP44. On the other hand, evidence abounds that lift pump failures with the resulting lack of cooling, is the bane of the VP44.

Personally I just view it as cheap insurance. BTW, I misspoke. I believe I was under the impression that the stan helped to protect the lift pump. The lift pump being compromised is what takes out the vp44 (?) I have a fass that has been reliable and has lasted twice as long as the original lp. I dont know if I can attribute that to the fass or to the stanadine. But I keep using the insurance.

But Ive been led to believe by the tdr and a couple of well respected diesel mechanics it is to protect the vp44.

The best thing you can do for your lift pump and VP44 is to run on the top half of your fuel tank. Low fuel is hot fuel and hot VP. The fuller the tank the more it will gravity flow to the lift pump, less suction needed.

Been doing that since high school in all my cars. Even better insurance that I dont run out of gas.

So its the individual states that require ADDITIVES the BASE PRODUCT is the same. Gas is a GAME alll its self. We have RFG (reformulated Gas) for GAS crossing state lines. Different additives are added at the racks in most cases, there are only so many pipelines and to send one brand STOP the flow and clear the line then pump another brand would be a monumental task so they all refine to a standard send it to the rack and mix whatever additive they wish.

As I said so many variables it makes debating what works for who and why irrelevant without control. The control is variable due to variance in base stock as well.

Without a chemistry lab at the nozzle each time it’s hard to say what is going in the user fuel tanks. ASTM D975 and D613 leave a lot of wiggle room.

Due to logistics, Alaska implemented across the board on and off road 15ppm before the rest of the US. That was fun.

I used to use Stanadyne in my 98 12V. The injection shop I talked to said to fill the filter housing with it then run the truck when changing filter. Once all the emissions hit the trucks the formula had to change so I gave up on using it on my 11 and 15.

I remember when all the rage was amalgamated. Don't hear about it anymore.
