STA-BIL Diesel Fuel Stabilizer, 32 oz
Diesel ages differently from gasoline — it darkens, grows sediment and feeds microbial sludge — but it ages all the same, and a tractor that sleeps through winter deserves better.
Our diesel quart is the storage bottle for compression-ignition machines: pour it before the equipment shed closes and the fuel that waits in the tank stays ready to work.

Before the equipment shed closes for winter.
Stops the dark slide
Formulated against the oxidation that turns stored diesel cloudy, acidic and filter-hungry.
Sludge defense
Keeps the tank bottom from growing the black jelly that strands equipment in spring.
For everything compression-fired
Tractors, gensets, skid steers, the old pickup — one quart covers the yard.
Work-season insurance
The first warm week is for fieldwork, not for bleeding injectors and swapping filters.
