How long can diesel be stored?

[JDeereman]

I han't figured it out either.

I think we need an MIT professor in petroleum engineering for that one.

I just recently checked the tank for water by using water indicator grease.
(it's yellow and turns red when contacting water) I was expecting at least an inch or two of water. NOTHING.

Can i ask where you buy such stuff? i'd like to get some. sounds like a very useful test.

I was interested, too.... here's what I've found..using COPERNIC and searching on " diesel water indicator test"

http://www.kaagat.com/2008 Johnson Test Papers Catalogue.pdf

says: Water Finder Paper provide a quick and reliable method to detect water in solutions such as petrol, diesel and other non-miscible liquids. The paper is simply attached to a dipstick and if water is present in the fuel it will remove the chemical surface of the test paper leaving only the white backing paper behind, providing a very clear indication. Apart from the detection of water in oil, petrol or diesel, water finder papers are suitable to work with other non-miscible solutions. Any suspended drops of water are shown as white spots.

I didn't locate cost or where to buy.

this seems like the cat's meow for keeping your diesel clean:
Automatied Fuel Polishing and Filtration System

Kolor Kut is what we use.

Kolor Kut Paste

I think we use to use one called sargel or something similar.

You and me both. and here is the part that confuses me more than anything else. suppose you buy a 250 gallon tank and have it filled on day one. then you use 125 gallons the first year and have it refilled. then you use 125 gallons the second year and have it refilled again.

question: after that second refill at 2 years and one day after buying the tank, how the heck old is your diesel fuel??????

Theo

Seems like assuming complete mixing you have 62.5 gal of two year old diesel mixed with 62.5 gal of one year old and 125 gallons of fresh. Is this like a high school quiz? LOL

Not exactly sure of the spelling but Sargel is popular among gas stations and marinas for water dectection. It's a grey/white paste that turns violet when water is present.

Just searched it SAR-GEL

SAR-GEL is what I have at home. Alway's seems to work well for me
