Things to Consider Before Buying the Best Engine Assembly Lube

Before you make your final decision on what engine assembly lube you will go for, I urge you to look at the following pointers. I bet they will help you make the right choice:


Speaking of composition, engine assembly lubes come in two main compositions namely petroleum-based and Molybdenum sulfide-based lubricants. As you may be aware, Moly-based engine assembly lubes have been around for decades even centuries. In fact, some say the lubes have been in the market since 1800s.

As for petroleum-based, they came much later but the lubes have gained unprecedented popularity. However, here is what you need to know about the two that will help you make the right choice:

  • Moly-based – they are famed for blending with most engine oils. Besides, they come with additives that help enhance engine performance after assembly. Whether the temperature or pressure is high or low, this lube does not change its structure. However, it is not a good choice for a camshaft because of its tiny silicone beads.
  • Petroleum-based – the first thing about this is their price. Yes, they are relatively cheaper compared to Moly-based lubes and you can’t tell me that you don’t want to save! The other thing is that they are readily-soluble in engine oil. Most significantly, petroleum-based lubes have no limits. You can apply them generously on any part of your engine.

Mode of Application

The mode of application of an engine assembly lube depends on two things; the viscosity of the lube itself and the container in which the lube comes in. About the former, most lubes have the same viscosity, which is normally medium.

On the part of a container, packaging is usually diverse. You can get a lube in a metallic bottle, plastic bottle, or even a tube. Even with the tubes, there are those that are easy to open to apply, while others that are hard to apply.

In most cases, going for tubes with pointed lids that make it easy for you to apply would be a prudent choice.


This is key. Additives play an important role in your car engine. Some additives offer additional guard on the essential parts of the engine. Although you might not know out rightly, which additive is in the lube, some manufacturers point out on the label.

Frequently Asked Questions (FAQs) About The Best Assembly Lube for Engine Building

Q: Is the engine lube necessary?

A: Of course it is. Whereas the regular engine oil will take a few seconds to travel to all the needed parts, a well-chosen lube will travel much faster thus help during pre-assembly and startup thereafter.

Q: Where do I apply the assembly lube?

A: While the lube is labeled engine lube, it doesn’t mean you apply every part of the engine. Instead, you need to apply on the important parts that need surface protection against friction, corrosion and wear. Some of these parts include camshaft drive gears, valve stem tips, rocker arm, pushrod tips, distributor drive gears, blower drive gears, lifters, and of course the cams.

Q: How do I lube a cylinder?

A: The first step is to clean the piston. Then you apply the lube on the piston’s exposed parts. Lower, raise, and rotate the piston without the cover to lube all its parts.

Q: How do I lube a camshaft?

A: Lubing a cam depends entirely on its location. For a cam that is attached to the cylinder head, you will lube it through or using the head feed. Alternatively, you can lube it via passages that are in the main gallery.

Final Thoughts

Remember, when you are assembling a new or old engine, you are actually laying one metal over another or fixing two metals together. As you may beware, that machine will not move because there will be massive friction. Within no time, the metallic parts will wear out.

To prevent any further damage on the parts, you need the best engine assembly lube, which will take care of immediate friction and subsequent wear, corrosion, rust, and tears. Besides, we have also seen that you cannot equate grease with lube. Thanks to its viscosity, mode of application and function, the best assembly lube for engine building will go a long way in helping your engine during assembly and startup.
