How many gallons of tank do you need? Whatever you burn in three to six weeks, plus a 10% cushion you never touch. That is the rule. Any less and you live at the mercy of the delivery truck; much more and you paid for steel that will always sit empty.
Second in importance: capacity triggers paperwork. In the United States, the EPA’s SPCC rule applies once aggregate aboveground oil storage exceeds 1,320 gallons (counting containers of 55 gallons or more). In Argentina, a single tank of 50 m³ (about 13,200 gallons) — or a site totaling 100 m³ — enters the national aboveground tank registry created in 2025. Sizing is not only a consumption calculation; it also decides which filings you will make.
If your machines and vehicles burn 100 gallons of diesel per working day, that is about 2,000 gallons a month. A 2,600-gallon tank gives you a long month of autonomy. And more: it lets you buy when the price is right instead of when the gauge forces you, because bulk diesel negotiates better by the full truckload. A well-sized tank is a purchasing tool.
For decades, farms stored diesel in 55-gallon drums stacked by the barn. It worked. Badly, but it worked — with more handling, more spills and more chances for water to get in. Today a combine at full harvest pace can burn more than that in one long day, and the drum belongs in the workshop.
A 2,600-gallon tank does not give you 2,600 gallons of diesel to use. It is never filled to the brim: you leave room for thermal expansion and so the delivery does not overflow. And the bottom below the pump suction is not usable either, because that is where water and sludge collect — exactly what you do not want in an engine. Between the two, count on 85 to 90% of nominal capacity as working volume. If the math comes out tight, go up one size.
Ask your distributor which truck they run and how much it drops per delivery. If the tank cannot take a full drop, you will pay extra freight or buy in quantities that do not suit you. The ideal tank takes the whole delivery with the safety margin intact — and a tank sized to the truck also cuts delivery fees and the number of hose connections made next to your equipment. And think seasonally: a farm that triples consumption at harvest must size for harvest, not for the yearly average.
Is consumption growing? Buy for next year. The price gap between a 2,600 and a 4,000-gallon tank is far smaller than buying twice. Where will it stand? Space and safety distances can decide the shape: wide horizontal or compact vertical. Single or double wall? Without a concrete dike, double wall solves containment in the same footprint. And if the product is in doubt, review diesel vs gasoline tanks first: size also depends on what you store.
At Indumor we build the full line, from 400 to 16,000 gallons, with export packaging.
How many gallons of tank do you need? Now you know the math: three to six weeks of consumption, plus 10% you never touch. We handle the rest in the shop.
With that number we quote the exact tank: not a gallon of steel too many.
