This case contains four 1 gallon diesel-stabilizer containers. Calculated capacity is 1,280 US gallons in-season or 640 US gallons for storage per container; the case totals 5,120 US gallons in-season or 2,560 US gallons for storage. Diesel fuel care requires a product selected for the fuel and operating pattern. This case-pack diesel fuel stabilizer is intended for documented tasks including limiting sludge and sediment formation and supporting injector cleaning and lubrication. It is separate from gasoline Storage and Marine formulas.
Order quantity matters: this listing supplies 4 separate containers of 1 gallon each. A case does not change the application directions for an individual unit. Plan remaining stock around the label’s storage instructions rather than assuming a fixed number of engines or seasons.
Dose selection depends on whether the diesel is in regular use or being treated for storage. The manufacturer publishes different rates for those two tasks. Plan the fuel quantity first, then measure the additive instead of treating the container’s maximum in-season capacity as the correct dose for every situation.
For boats, generators or other diesel equipment, follow the engine manufacturer’s fuel and service requirements. Additive treatment does not replace inspection, separator servicing or removal of contamination where service is required. Do not describe this product as a biocide or assume it provides an unverified anti-gel temperature rating.
Compare the listed case with single-container packages when deciding purchase quantity. Choose based on current prices, the amount of diesel to be treated and the intended in-season or storage task. Retain a record of the measured dose and follow the supplied label’s handling and storage instructions.

Strong performance, solid bulk option
The 1-gallon STA-BIL Diesel Formula effectively prevents sediment, removes water, and lubricates injectors on my diesel workboats. Case of four arrived on time and offers good value.
