7. Royal purple 01335 assembly lubricant

Royal purple 01335 assembly lubricant

We chose this product primarily because of its unique formula. Royal purple is a synthetic lubricant. So, what does it mean?

Being synthetic, it offers robustness to the user for reassembling purposes. In other words, you get longer usage per dab of lube applied on your equipment.

The synthetic nature also aids the substance to gain a greater adhesion than other similar products. The enhanced adhesion makes the metal surface firmly stick to one another.

The lubricant also creates a super, load-enduring physical barrier between the metal surfaces, making reassembling a smooth process.

The synthetic formula is also responsible for enhancing the anti-rusting ability of the lubricant. Thanks to the carefully fabricated synthetic molecules, the lubricant can protect both ferrous and non-ferrous metals against the effect of rust and corrosion.

Rusting is inevitable when it comes to metal equipment. Doing something to prevent rusting can never go wrong.

Another wonderful thing is it is slickness. When it comes to being slick, this one wins compared to grease.

With it, you are getting a smooth performance for assembling parts and no longer need to worry about friction hampering your operations.

Highlighted Features

  • The synthetic formula makes the product durable so you can get better performance per dab of lube applied
  • Protects your equipment against rust, so you get better life on internal components of your engine

Fantastic product if you are looking for assembling lubes and don’t have a lot of experience under your belt.

The adhesion is remarkable. It can brilliantly hold your parts together in place. We liked how it has a certain level of natural stickiness.

Often lubes are over-sticky, making working with them difficult. On the other hand, this one makes it look like a walk in the park.

A cool feature is its color. We are sure that you are asking, “How does it help me out?”

9. Maxima racing oils professional assembly lube oil

Maxima racing oils professional assembly lube oil

This unit is an exceptional film-forming lubricant that can give you exceptional performance.

For example, thanks to a layer of the film formed in between the parts, the moving components will stay safe and damage-free. This is crucial when your engine is under heavy stress.

The layer of films also protects your precious engine from surface wear. Wear of metals is a common scenario in machines when the machine is subjected to intense work, stress, or friction.

Your engine is not an exception too. This means regular wear can damage your engine, lowering its shelf life.

This lube protects from wear that can arise from any situation. This means a say hello to a better and long-living engine.

Another excellent feature is how easily this lubricant mixes with substances such as petroleum or synthetic oil. This prevents your engine filters from being plugged.

Now, why is this important?

You see, when filters are plugged in, your engine will start showing red flags. Engine health takes a toll, and engine performance goes down in engine misfires, rough idling, and uneasy starts.

Having a lubricant that promptly mixes with other oils is a blessing. Your filters won’t get plugged, and you will get an uninterrupted engine performance.

Highlighted Features

  • Film-forming lubricants protecting your engine components during movements
  • Protects your engine components from wear and tear, leading to a longer engine life
  • mixes easily with other oils, so get zero filter clogs and say hello to smoother engine performance

10. CRC engine assembly lube

So far we have talked about many products, but it is safe to say that we kept the best for the last.

How so?

To start, we found the ingredient of this lube very fascinating. This product is a “lithium 12 hydroxyl stearate based” grease. Too complicated?

In layman’s terms, this is not your average grease-based lube. Instead, we think this is far superior lube. Its advanced ingredient makes it a super adhesive lube.

It grabs onto metal surfaces far stronger and superior to that of other similar products. Also, the lube is very thick. This is because it is made up of graphite and moly.

Being super thick means it moves very little, almost doesn’t move at all. So you don’t need to worry about it being runny all over the applied spot giving you more than you can handle.

Assembling an engine is craftwork, and craftworks need to be neat and accurate. This tube is just the right size, and it will fit perfectly in your palms.

You can work with ease and confidence without thinking about putting too much or too little. A perfect fit leads to a perfect dab.

Highlighted Features

  • Advanced ingredients so you get a far superior adhesion than other products
  • Super thick lube, so you won’t have to worry about getting dirty
  • Tube fits in your hand perfectly, so you get just the right amount

Best Assembly Lube Buying Guide

Suppose you finally go put to buy some lube. The question is, “How will you decide which one to buy?” Most people just buy the one that fits their budget, and that’s a gross mistake.

You want to buy the item that you need. You don’t want to overbuy or under-buy. You need to buy something that fits your profile and serves you right and for a long time.

This section will contain all the things you need to know before you go out to buy lube for yourself. Have a quick go-through so that you can beat the market and get yourself the best engine assembly lube.

Size

Most lubricants in the market come in either 4 ounces or 10 ounces of bottles. If you are tight on a budget, go for the former.

On the other hand, if you feel like you have money to spare, plus you would not mind having a few extra left after assembling a full engine, go for the latter.

A few brands in the market come in 10oz and can last for many days. These brands give the user a high value for money. We have also included some of them in our list.

Ask yourself about your preference, then go for the one that suits your need the most.

Slick

The primary purpose of applying lube during build-ups is to smoothen out the process by cutting off the friction between the engine’s parts initially.

The extent to which a lubricant can reduce or eliminate friction is determined by the “slickness” of the lubricant.

You should be buying highly slick lubricants. The slicker the lube is, the more slippery it makes your equipment, and the less is friction.

Friction can hamper your setup and cause damage to your engine in several ways. It is always the best practice to get rid of friction whenever you set up an engine, and “slick” lubricants are the ways to do it.

Adhesion

This refers to how much your components grip or adheres to each other after applying the lube. You should go for lubes that are adhesive.

Why?

Because the gripping effect will take pressure off your chest, and attaching the parts will get easier.

Best Assembly Lube

When you assemble, reassemble or replace parts in an engine, it is always helpful when the parts grip each other.

That is why you should always go for a lubricant with a high adhesive feature.

Resistance to rust or corrosion

This is a must-have feature in the lube that you are buying. Rust can be the death of metals. Rust damages metals, and with time, it can tear metal apart.

Your engine or the assembled parts inside it aren’t any different. They are metals and, unfortunately, subject to rust.

That is why we highly recommend you get a lubricant that is resistive to the effect of rust or corrosion.

When you apply such lubes to your engine, the engine stays intact against rust, and in the long run, you get a longer shelf life and a healthier engine.

We cannot emphasize the importance of this enough.

Thick/Thin

Some parts require a thick layer of lubricants. And others need a subtle, thin layer. So before you go out to buy, ask yourself where do you want to apply it and then buy accordingly.

One word of caution we would like to pass is that thin lubricants naturally are not supposed to stay in the applied spot.

So, if you are going to buy a thin lubricant, our suggestion would be to look for a lube that is thin and yet does not run or move away.

Otherwise, working with it would be very difficult as it runs away and makes the workstation and your hands messy.

Getting the right one means a lot of searching in the market, and finding the right one can be exhausting. Thankfully we have included a few products that are both thin and not too runny. Check it out.

Water-Resistant

A very underrated feature that most people overlook. Explaining a water-resistant lubricant is futile. The name already does that.

However, we like to point out that water-resistant lubes can be handy as they protect your parts from moisture, adding an extra layer of protection and assuring a long shelf life.

Yes, we know what you are thinking. This feature sounds extravagant. And, it is somewhat. But, if you have money to spend and looking for that extra layer of protection for your precious engine parts, then this is definitely a sound purchase.

Frequently Asked Questions

#1. In which places do you apply the engine assembly lube?

Even though the name says engine lube, it does not mean you put it on the whole engine. Instead, you will only apply lube to those specific parts that need initial surface protection because the oil still has not traveled there yet.

#2. How important is engine assembly lube?

If you ask us, we would say very. Now, you might think we are exaggerating, but we can honestly say, NO, WE ARE NOT!

This is because engine oils need some time to reach all the places inside the engine. During these few seconds, the surfaces of the components can clatter with each other, causing metal wear and other similar issues that can harm your components.

This is where lubes enter the scene. If you apply lube to these parts, the lube will eliminate friction and allow the smooth running of the components. These will keep your parts safe and make them long-lasting.

#3. Do engine assembly lubricants dissolve with oil?

Yes, they do. Once in contact, the lubricants mix with oil, keeping the engine safe from unwanted residue.

#4. How to apply lubricants in a cylinder?

As a rule of thumb, first, clean the piston. Either you remove debris from a new or clean the gunk from an old one, always start by cleaning the piston. Next, raise the seat (maximum level) and put a dab of lube to the exposed parts.

Once you are done with this, repeatedly raise and lower the seat. Remember that this step has to be done while rotating. This will help to spread the lube properly.

#5. Can grease be a substitute for assembly lube?

Simple or basic grease can never be an alternative to assembly lubes. This is because two factors come into play while doing this.

Firstly, grease is not thick enough. It cannot sit and gel in the applied spot like an assembly lube. It can simply move off to the rest of the components where lubrication might not be needed.

Secondly, engine assembly lubes are soluble in engine oil, whereas grease may not be entirely soluble.

If both have not mixed in together completely, it may cause leftovers that lead to engine blockage. In this long run, you would just be damaging your engine.

Final Words

The absence of something as simple as a dab of lube can ruin all your hard work and can bring your engine downhill.

Without lubricant, your engine stays dry, and the parts clatter with each other leading to poor performance and deteriorating health.

A lubricant can be the difference. A lubricant can be the game-changer that can take your engine performance miles ahead, add years to your engine life.

If you have been with us so far, you have already laid your hands on the best engine assembly lube in the market. We have also included a buying guide to inform you of all the traits you want in your lube.
