How to Find Your Favorite Automotive Grease Guns – The Ultimate Buying Guide

To understand which type of grease gun will work best for your projects, consider a few factors.

Types of Grease Guns:

As there are different types of grease guns available like hand lever, pistol grip, hand pump or handgrip gun, battery-powered, etc. While hand lever guns are mainly manually powered, mechanical tools, a pneumatic grease gun is suitable when your projects don't need super-high PSI. Battery-powered grease guns provide more freedom of movement while working and deliver the highest pressure of all with consistent pressure to force out grease.

Nozzle:

The nozzle is another important factor for grease guns, which helps to deliver proper grease. There are mainly two types of styles available: one is a straight nozzle, and the other one is a flexible metal nozzle. Flexible metal nozzles help to reach difficult areas easily, and they also help to improve accuracy.

Barrel Size:

The importance of barrel size may vary based on the primary objective of using the grease gun. Bigger barrel size is suitable for a lot of grease in a short amount of time, while a smaller barrel is okay for you if you want to use it only for small specialty applications.

Ease of Use:

Make sure to choose only the grease gun that can easily handle and use to complete your task. This tool is mainly used for simply lubricating your machinery. The design, weight, and size of a grease gun are essential things to consider while buying a grease gun.

An automotive grease gun should be easily installed and assembled whether you are experts or beginners. It should assist you in doing your job as much as you want. Moreover, it should have a comfortable handle to hold it for a long time without causing any pain in hands. Some grease guns also allow you to operate in a one-hand operation.

Storage Case:

To protect a grease gun and its other elements, it should have a solid carrying case. A grease gun that comes with a storage case will last longer than other regular grease guns because it won't be exposed to shop dust and other components.

Materials:

Metals are mainly used to make most of the grease guns. They are durable enough to last a few years easily and can withstand even high pressure. There are also plastic types of grease guns available in the market, which are considered as inferior quality because they are prone to wear and breakage.

Safety and Durability:

Make sure the grease gun you will use is safe and has strictly followed safety standards. Some grease guns come with a safety lock feature to ensure safety for your children. To know about your grease gun's durability, you can get some customer reviews to get a good idea about it. You should also check the warranty period of the grease guns. It should be a minimum of one year.

Pressure and Accuracy:

Lower pressure guns help to aim specific areas with more accuracy, while higher pressure guns are suitable to cover larger areas with less time. If you require variable pressures, then buy a gun that allows you to change the pressure in different situations based on your requirements.

Accuracy may not be important for household tasks, but if you want to use grease guns for professional purposes. Then go for a particular gun which comes with a reasonably narrow stream that allows you to get into harder to reach areas easily without any problem.

Warranty:

To ensure the security of purchase and worry-free use, warranty is an important thing to consider. A more extended warranty with good terms makes it more reliable for customers and attracts them to buy the product.

Price / Budget:

Price or budget is another essential thing to consider because most of the cheap guns are of low quality. So, if you want to have a premium quality grease gun that can work smoothly without causing any problem, make sure to invest some money. But that doesn't mean you have to spend all your money to buy a good grease gun. Even on a tight budget with proper knowledge, you can find the perfect grease gun for your DIY projects.

Final Thoughts

As there are multiple grease guns available in the market which can be fit into simple categories for general household and car maintenance uses. They are easy to use and maintain as well as save your money. But if you want something for professional purposes, then we recommend the pneumatic guns.

All the best grease guns we have mentioned are a great choice to do any job easier for your DIY projects. Our top pick is the Bravex Grease Gun due to its efficient grease delivery system and easy to operate.

Grease Gun FAQs: 

Whether you intend to purchase a grease gun for your automotive machine or any industrial machine, you should come up with the top-rated grease gun on the market. That being said, before purchasing a grease gun, we often find some common questions. Let's have a look.

How do you load a grease gun?

Ans: There are mainly two methods for the loading process of a grease gun: one is a reservoir or regular barrel grease gun, and the other one is a cartridge grease gun. For a reservoir grease gun, you need to separate the grease gun's head, locate the end of the barrel into the grease, fill the barrel with grease, and sew up the barrel to the head of the grease gun. For the cartridge, you need to unscrew the cap of the cartridge, take out the vacant cartridge, and put in an intact one.

How to clean a grease gun?

Ans: To properly clean your grease gun, you must follow some steps and processes. First, take off the old grease cartridge from the grease gun and use a clean cloth to clear all dust, debris, and residue from external and internal nozzles and other parts. Use the right solution to wash the internal and external parts of the machine. You can rinse them in hot water to clear all types of residue and debris from the grease gun. Make sure to dry the machine before loading a new grease cartridge completely.

What is the best lubricant to use with grease guns?

Ans: A high-quality lubricant is preferable to use with grease guns because it will flow freely across the gun without having any build-up problems in nozzle areas. Make sure to choose a specific lubricant that can match up with your dedicated grease guns. A good quality grease lubrication does not leak because it has sealing properties and protection grits from corrosion. Make sure to release a fair amount of grease for lubrication to perform at its best.

How should I store my grease gun?

Ans: Cartridge tubes of grease should always be stored in an upstanding position. A grease gun should be cleaned properly through depressurizing it if any cartridge tube is left in it. Make sure to remove any contaminants by using any soft fabric cloth and keep it in a flat position where the place is cool, dry, and clean to avoid exsanguinating the oil.

How much grease comes out through a grease gun?

Ans: Though it mainly depends on your grease gun's size, the standard output range is typically between 0.5 and 3 grams. The actual output of grease may vary since it depends on the age of your grease gun and also it's model. To make more precise with consistent output, make sure to calculate your gun's output range as per stroke. To measure a specific amount of grease, you can use a calibrated scale, which will give you the output per stroke.

Is it possible to under or over-grease?

Ans: If you are likely to go under grease if you use very little grease, it may cause dry friction and wear out. On the other hand, if you use too much grease at the same time, which is also called over-grease, you may face the risk of increasing temperatures of the stirring parts. It may ruin the seals of the grease gun, and the grease consumption rate will increase. So, you should calculate grease output properly per stroke to save you money as well as allow your machine to work more efficiently.
