Common questions
What pressure grease gun do I need for a truck?
For most truck fittings, a grease gun that delivers at least 6,000 PSI is adequate. However, for stubborn or rusted fittings, a higher pressure like 10,000 PSI is better. Look for models that specify high pressure output.
Can I use a grease gun on all types of grease?
Yes, grease guns are designed to handle standard chassis grease. They work with cartridges or bulk fill. Always check the grease consistency; some high viscosity greases may require a higher pressure gun.
How often should I grease my truck?
It depends on usage. For heavy use, greasing every 3,000 to 5,000 miles is recommended. For daily fleet trucks, follow the manufacturer’s maintenance schedule. Regular greasing prevents wear.
Are cordless grease guns as powerful as manual ones?
Many cordless models offer similar pressure, up to 10,000 PSI. They are convenient and fast, but they rely on battery life. For continuous heavy use, a manual or air gun may be more reliable.
What is the difference between lever and pistol grip?
Lever guns deliver more pressure per stroke and are suited for heavy duty. Pistol grip guns are easier to use one handed and fit in tight spaces. The choice depends on your comfort and the tasks.
Do I need a flexible hose?
A flexible hose is helpful for reaching difficult fittings, especially on trucks where space is limited. Many grease guns come with both rigid and flexible hoses. Having both is ideal.
How do I remove air from a grease gun?
Most grease guns have a bleed valve. Pump the handle with the valve open until grease flows without air bubbles. Then close the valve. This ensures consistent pressure.
Can I use a grease gun for other applications?
Yes, grease guns are versatile for lubricating various equipment, such as tractors, trailers, and industrial machinery. The same gun can be used for multiple purposes if cleaned properly.
What is the best way to store a grease gun?
Store it in a clean, dry place. Keep the coupler protected to avoid dirt. For battery models, remove the battery if storing for a long time. Regularly check for damage.
Are expensive grease guns worth it?
Professional grade guns from brands like Lincoln and Milwaukee are built to last and perform reliably. For daily professional use, the investment is justified. For occasional use, a mid range model may suffice.
The bottom line
For professional truck maintenance, choose the Lincoln 1162 if you prefer manual control and maximum pressure. If you want cordless convenience, the Milwaukee M18 is the best choice. For high volume shops, the Ingersoll Rand air gun is the top pick. Avoid the Matco 4-in-1 unless you need multiple modes and have a big budget.
