PRI-G/D vs Archoil - means of preserving and differences

[Spring1898]

Just wondering if anyone has the low down on how these additives work differently based on their formulations.
Also wondering what makes PRI different from your standard STA-BIL.

I have used archoil for 'long term' storage for both diesel and ethanol free gasoline with good results. This was back when archoil was more concentrated than it is now.

Is PRI-G or D better or meaningfully different based on its proposed mechanism of stabilization?

I used PRI-G for a number of years, then switched to Marine Stabil 360 due to Stabil is on the shelf at local stores and easier to get.
I didn't have any problems with PRI-G. All my engines started fine after storage.

If I remember correctly, PRI claims to be able to "restore" old gas and old diesel fuel. I'm skeptical about this claim as ageing fuel is a chemical process (evaporation and chemical changes) that isn't magically reversed by adding 1oz of brown liquid into a 5 gallon gas can. So, due to the crazy claim and being a hassle to buy, I switched to Stabil. No problems to report with Stabil.
