Stanadyne Lubricity Formula diesel additive — 2 Pack 64oz jugs (treats 500 gal) high‑content concentrate for injector & pump prote

Stanadyne Lubricity Formula is a concentrated diesel fuel additive sold as two 64‑ounce jugs, each designed to treat 500 gallons of diesel to improve fuel lubrication and help protect fuel system components.

Whether you operate high‑mile highway tractors, agricultural equipment, or a mixed fleet, fuel lubrication affects injector life and pump wear. This Stanadyne two‑pack supplies a high‑content lubricity concentrate approved by many OEMs and formulated to reduce metal‑to‑metal contact inside modern fuel systems. You can blend it with other Stanadyne products if desired, and it’s engineered for year‑round use in systems that need extra lubricity.

How does Stanadyne Lubricity Formula protect diesel fuel systems?

The formula adds lubricating molecules that form a thin protective film on injector and pump surfaces, helping reduce friction and wear. It also contains agents that help limit rust and corrosion forming in the fuel system.

• High lubricity concentration—five times more than other Stanadyne additives
• Forms a hydrodynamic film on metal parts to reduce abrasion
• Contains corrosion inhibitors to protect fuel lines and tanks
• Compatible with modern diesel fuels and common system materials

Will this product work with my engine and other Stanadyne additives?

Stanadyne Lubricity Formula is OEM‑approved for use where Stanadyne additives are accepted and can be blended with other Stanadyne products. Mixing is safe — double‑dosing isn’t harmful, though it may not produce double the effect.

• Approved by many Original Equipment Manufacturers
• Formulated to be miscible with other Stanadyne formulas
• Safe for routine, year‑round application when OEMs recommend Stanadyne
• Follow vehicle or equipment OEM guidance for additive choice

How do I dose and apply the 64oz jugs?

Each 64‑ounce jug treats up to 500 gallons of diesel. For small tanks or service stations, measure the correct volume per 500 gallons; for fleet fueling, add proportionally at the dispenser or blending point.

• Each jug treats 500 gallons — scale dose linearly for other volumes
• Use proper measuring equipment or calibrated dispensers for accuracy
• Shake or invert jug before adding if recommended by your maintenance practice
• Store in a cool, dry place away from direct sunlight

What specific improvements can I expect after using it?

Users typically see smoother pump operation and reduced wear over time when fuels lack sufficient natural lubricity. The formula also helps keep injectors and system passages cleaner, which supports consistent fuel delivery.

• Reduced injector scuffing and pump wear
• Cleaner injectors and fuel passages from built‑in detergency
• Reduced rust and corrosion risk in fuel systems
• Improved reliability for high‑stress diesel applications

Who is this for: This Stanadyne Lubricity Formula 2‑pack is aimed at fleet managers, agricultural operators, diesel service shops, and anyone maintaining high‑use diesel engines where lubricity or excessive wear is a concern. It’s especially useful when OEM guidance approves Stanadyne additives or where fuel supplies may lack adequate lubricity. If you need a concentrated, OEM‑friendly lubricity boost that’s safe to combine with other Stanadyne solutions, these two 64‑ounce jugs provide a practical, measurable way to protect fuel systems across multiple tanks or vehicles.
