Best 3 OZ Grease Gun Buying Guide:

When trying to select the best mini grease gun, you must keep a few things in mind to make sure you buy the best one for you. If you choose one at random, you may find it does not fit your purpose. We want to help you buy the best 3 oz grease gun suited to your preferences. Let us look at some factors to keep in mind.


If you are looking to buy a small grease gun, chances are you want the ease of usage and transportation. You need to make sure the tool you are getting is of a convenient size.


Since small tools can be challenging to handle, you need to make sure your grease gun has mechanisms and materials that ensure a good grip. If you can hold it well and not have to stress about it slipping away and making a mess, it will take a lot of stress away from the lubricating process.

Pressure/Precision Trade-off

You cannot have high pressure and precision from the same device, so pick one and pick carefully! High-pressure devices are better for cases where you need a quick and easy application but don’t care much about the mess created. Devices with lower pressure will be better to get a precise application. You will find this helpful if you’re working on older cars, machines with lots of nooks and crannies, and equipment with hard-to-reach places.


Grease guns made of metal are better option. These give grease guns long service lives. Plastic would be the least preferable, as it may disintegrate quickly. You want your device to last long, so choose one that has good plating and is durable. Devices made from cheaper materials may save you some money but will most likely give you twice the trouble while working with them. Also look for chrome plating that could protect your device from corrosion. 


You need to make sure you get the correct type of grease gun for your essential purpose. You need to know if you’re okay with pumping manually or would prefer electric grease guns instead. Also, decide early if you want something wireless or if you’d like a cord.


High-quality tools operate better and make life easier. Make sure you are getting a good quality grease gun from a brand that makes industrial-strength tools as well. These will likely last longer, perform better, and ensure the precision of application or high pressure, whichever you prefer! You should buy your tool from a manufacturer specializing in tools made for heavy machinery and gear for professional work.

Keep these factors in mind to find your perfect fit!

Types of Grease Guns:

We can sort grease guns into three main categories depending on the type of operation. Let us look at each type and its purpose.

Hand Lever

These are manually operated grease guns. You use this type by hand. You fill it up and then pump. These types of grease guns are best for when precision is not required. They can build up to a high amount of pressure.


These use air pressure to pump grease. The amount of oil delivered can be controlled, but ones that dispense a fixed amount of lubricant are also available. These are best to use when too much power is not required and precision is more important.


These are usually the most powerful and have a high capacity but can still provide precise application. These devices are wireless, which makes them more convenient to carry around and use. You can adjust the amount of grease dispensed. These are best for heavy machinery and heavy-duty lubrication work.

When buying a grease gun, make sure you buy the right type to fit your purpose best! Getting a hand lever grease gun is not recommended for heavy-duty machinery (unless specified). We would not recommend buying a pneumatic grease gun if you require high pressure on a similar note. Whether you decide on electric grease guns or manuals, make sure you are clear about your choice.
