This case contains four 32 oz diesel-stabilizer containers. Calculated capacity is 320 US gallons in-season or 160 US gallons for storage per container; the case totals 1,280 US gallons in-season or 640 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 32 oz 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.

Solid diesel additive, convenient case
The STA-BIL Diesel Formula stabilizes fuel, prevents sediment, and improves injector performance on my diesel powerboat. Case of four arrived on time and is good value. Four stars only because the measuring spout could be a bit more precise for exact dosing, but overall results and service have been reliable.
