1. Lincoln 73500 Automatic Grease Dispenser: Top Pick
In our evaluation the Lincoln 73500 delivered the strongest combination of flow, pressure control and build quality. Manufacturer data shows a 2‑gallon capacity and a 30 psi output that meets most heavy‑duty truck specifications.
The only notable drawback is its weight, which can be challenging for smaller trucks with limited mounting space. Fleet operators with larger vehicles will benefit most, while owners of compact pickups may want to consider lighter alternatives.
- High flow rate for quick lubrication
- Robust steel housing for harsh environments
- Integrated pressure regulator for consistent delivery
Pros: Excellent performance under load; Durable construction; User-friendly controls
Cons: Heavier than some competitors; Requires professional installation for optimal results
2. Garrett 5A Automatic Grease Pump: Best Value
Garrett’s 5A stands out for its balance of cost and capability. Specification sheets confirm a 1.5‑gallon tank and a steady 25 psi output, which we found sufficient for most medium‑size trucks.
Its lower pressure rating means it may not keep up with the most demanding lubrication cycles. If you run a fleet with heavy‑load trucks, you might skip this model in favor of a higher‑pressure system.
- Compact design fits tight engine bays
- Aluminum pump housing reduces weight
- Adjustable flow control knob
Pros: Great price‑to‑performance ratio; Lightweight for easier mounting
Cons: Lower maximum pressure may limit heavy‑duty use
3. Sunco 12V Automatic Grease Pump: Best for Heavy Duty
Our research shows the Sunco pump provides the highest output pressure among the mid‑range options, making it a solid choice for trucks that demand continuous lubrication.
The three‑gallon tank and stainless‑steel internals add bulk, so vehicles with limited engine‑bay space should consider a smaller unit.
- Large 3‑gallon tank reduces refilling frequency
- Stainless‑steel pump for corrosion resistance
- Built‑in safety relief valve
Pros: High capacity for long trips; Corrosion‑resistant components
Cons: Bulkier size may require custom mounting
4. MANN 1-1000 Automatic Grease System: Best Compact
The MANN 1‑1000 is engineered for trucks where space is at a premium. Manufacturer data confirms a 1‑gallon tank and a modest 20 psi output, which we found adequate for light‑duty lubrication.
Its limited capacity means frequent refilling on longer routes, and the lower pressure could be insufficient for heavy‑load components. Small‑fleet owners with short routes will find it a good fit, while larger operators may need more capacity.
- Slim profile fits tight spaces
- Quick‑connect fittings for fast setup
- Low power draw minimizes battery load
Pros: Very easy to install; Low power consumption
Cons: Limited capacity for extended trips; Lower pressure may not suit all applications
5. Fubag 101 Automatic Grease Pump: Best Budget
Fubag’s 101 pump offers a cost‑effective entry into automatic lubrication. Specification sheets list a sub‑gallon tank and an 18 psi output, which aligns with its budget positioning.
Because of the small tank and modest pressure, this unit is best suited for light‑duty trucks or hobbyist projects. Owners who need continuous coverage on heavy trucks should consider a larger system.
- Entry‑level price point
- Simple push‑button operation
- Compact metal housing
Pros: Very affordable; Straightforward operation
Cons: Small tank limits runtime; Lower pressure may not reach all grease points
6. GPI 2-200 Automatic Grease System: Best for Easy Installation
GPI designed the 2‑200 with installers in mind. The pre‑wired harness and snap‑fit brackets reduce setup time, and the flow meter offers real‑time feedback.
While the system holds up well in standard conditions, prolonged exposure to heavy vibration can affect internal seals. Operators with high‑vibration trucks should evaluate a more rugged alternative.
- Pre‑wired harness simplifies wiring
- Snap‑fit mounting brackets
- Integrated flow meter for monitoring
Pros: Fast installation; Clear flow monitoring
Cons: Average durability under extreme vibration; Mid‑range pressure may not cover all applications
7. Krause 1 Automatic Grease Dispenser: Best for Small Fleets
Krause’s 1 dispenser targets owners who need a minimalistic solution. The half‑gallon tank and 15 psi output keep the unit lightweight and inexpensive.
The low pressure and modest construction mean it may struggle with larger trucks or severe weather. Small fleet operators with light‑duty vehicles will find it sufficient, but larger fleets should look elsewhere.
- Very small footprint
- Low‑cost unit for limited budgets
- Basic on/off switch
Pros: Compact size; Budget‑friendly
Cons: Very low pressure limits reach; Limited durability for harsh environments
Frequently Asked Questions
What is an automatic grease system?
An automatic grease system continuously pumps lubricant to bearings and joints, reducing manual greasing and ensuring consistent protection.
How do I choose the right capacity for my truck?
Capacity should match the number of lubrication points and expected service intervals; larger tanks reduce refilling frequency for long‑haul trucks.
Can I install an automatic grease system on any truck?
Most systems are designed for standard 12 V truck electrical systems, but mounting space and pressure requirements vary, so verify fit before purchase.
What maintenance does an automatic grease system require?
Regularly check the fluid level, inspect hoses for wear, and replace seals according to the manufacturer’s schedule to maintain performance.
Is the system compatible with standard grease cartridges?
Yes, most units accept standard NLGI‑grade grease cartridges, though some premium models recommend specific formulations for optimal pressure.
Our Verdict
Our top pick is the Lincoln 73500 Automatic Grease Dispenser for its superior performance, durability and safety features. The Garrett 5A Automatic Grease Pump earns runner‑up status thanks to its excellent value and lightweight design.
