Niteo Motor Medic MF3-12PK
We start off with Niteo Motor Medic. This proprietary blend of detergents and solvents packs a punch. It also works faster than any other engine flush we tried. And while it offers maximum cleaning, this power doesn’t impact the lubricity of the oil.
Even if you’re using high-end synthetic oil in your car, that oil tends to break down leaving your engine exposed to damage. Motor Medic offers more protection than synthetic oil can provide.
One of the benefits of Motor Medic which sets it apart from the other products is how fast it works. All you need is just 5 minutes for the cleaning fluid to do its magic and flush out all the sludge, gums and dirt from your engine.
But that’s not all. Using Motor Medic to cleanse your engine you help restore the engine and unleash the power and performance that most engines tend to lose over time.
Moreover, regular use of Motor Medic reduces your oil consumption and soothes those noisy valves which tend to grumble and screech when they’re dirty.
While it’s not recommended to use Motor Medic for more than 5 minutes, it is perfectly safe to use with all engine types. Whether you’re running a gas, turbo, non-turbo, or even a diesel engine, Motor Medic works well with all these engine types.
In fact, from what we’ve observed, the fluid doesn’t damage any seals or lead to bearing wear. Just make sure to use it exactly as instructed.
Amsoil Synthetic Air Compressor Oil ISO-100
As far as air compressor oils are concerned this one is right there at the top. The high-quality synthetic oil is designed for all types of engines, especially heavy duty ones.
If you’re using industrial compressors, then you know that mechanical abuse, weather changes, severe duties, and driving conditions have their toll on the engine. Amsoil Synthetic Air Compressor Oil provides the kind of protection your harsh driving conditions demand.
And the best part? It has a service life that is eight times that of mineral oil. So by using this oil, you’re not only saving money but also extending the life of your engine.
This is something you will come to appreciate in this oil. It is both ashless and non-detergent. Why does this matter?
Well, for one thing, it won’t damage the internal parts of the engines such as seals and bearings. And while you can’t leave Niteo Motor Medic in your engine for more than 5 minutes, Amsoil Synthetic is perfectly safe.
And when you compare this premium synthetic oil with other mineral engine oil products, you’ll see that thanks to its extended life, it gives you a bang for your buck and saves you money in the long run.
Another great feature of Amsoil Synthetic is that it works rather well with different compressors. These include rotary vane compressors as well as reciprocating compressors.
And if you’re wondering whether it will work with the pumps in your engine, Amsoil was designed both for vacuum pumps and pressure washer pumps.
In other words, this oil is well suited to all kinds of engines that power our vehicles on the road.
Lubegard 40902 Bio/Tech Engine Oil Protectant
Lubegard 40902 is more than just another engine oil. It’s the engine oil for your car. Apart from its many benefits, this oil is easy on your wallet and promises to optimize engine performance and horsepower.
Lubegard works perfectly with diesel engines. It also runs flawlessly on gas engines.
But wait, there’s more. By reducing engine friction, Lubegard extends oil life by 30%, which translates into money savings and longer engine life.
And when you have a smoothly running engine, it also means a quieter engine — no more noisy startups during the cold months. With Lubegard the belches and squelches disappear, and the engine simply purrs.
Liquid Wax Ester is touted as the technology of the future. Lubricants that use LXE protect the engine from wear and friction. Suddenly your engine performs like a new one and stops giving you those incessant problems.
This is especially true in today’s engines. They’re more complex, so many moving parts, and with the power and speed these engines are built to offer, oil gets heated up which means it loses lubricity. And the more you change oil, the more dirt that piles up.
But Lubegard, with its anti-wear and anti-corrosion agents, ensures that the oil stays at a cooler temperature which prolongs its life and keeps the engine running at maximum performance.
There’s no doubt that fuel economy is one of the main reasons you buy a new car. But sooner or later and as the engine gets older, that fuel economy becomes a thing of the past.
Which is another reason why Lubegard is one of the best products on this list. When you have oil that saves not only on fuel but also improves the engine oil anti-friction capabilities, then you’re looking at some serious money saving.
Liqui Moly 2037 Pro-Line Engine Flush 
If you’re looking for a gentle engine flush that gets the job done in a simple but effective way, you won’t go wrong with Liqui Moly. The detergent-based liquid makes flushing and cleaning your engine a breeze.
Well, for one thing, there are no complex steps to follow or manuals to remember to read only after you’ve used the engine flush and then you start to blame yourself when you don’t get the results you hoped for.
Liqui Moly does away with all the complexity of the process. You just pour it in the warm engine and let it run idle for about 15 minutes. Then drain the oil, put back the filter, and refill your oil. It’s that simple.
Being simple to use is one thing, but how effective is it and does it work with all engines? The answer is yes, it is quite effective against all forms of dirt, varnishes, gums, and deposits that accumulate in your engine.
And since it works well for all engines whether they’re gas or diesel, you know you’re in safe hands with Liqui Moly. Even if the engine has solid particles or contaminated with other liquids and lacquer as it often happens, the engine flush does a good job isolating these particles and dislodging them from the inner parts of the engine.
If that was all Liqui Moly did, it won’t have a place on our list. Because, let’s be honest, with the new engines, one expects a lot more out of the engine flush than to simply clean the engine.
And on this front, Liqui Moly delivers as well. Any unprotected metal surfaces inside your engine are sitting ducks for corrosion. You can’t see them because how often do you take apart your engine and inspect its inner workings? Never.
But you don’t have to do that, because this engine flush does the job for you. It covers all those unprotected surfaces with an oily film that insulates it from the air and prevents corrosion.
Lubegard 98901 Engine Flush and Protect Pack
This is our second Lubegard product on the list. And for a good reason. While Lubegard 40902 works well for new engines, some high mileage engines require something milder.
And that’s what Lubegard 98901 Engine Flush and Protect Pack is here to do. It protects those engines with its revolutionary LXE technology. By reducing the engine temperature and minimizing wear and friction inside the engine, you can add a few years to your engine’s life.
Oil filters do a great job keeping contaminating particles from making their way inside the engine. However, there’s a limit to what these filters can do, and anything smaller than 25 microns passes through the filter.
The build-up can lead to huge complications not only to the engine’s horsepower but to its life and also the frequency of changing the oil.
And these particles of less than 25 microns, that are responsible for about 60% of the damage most engines face. Lubegard 98901 detoxes the engine and flushes all the gunk blocking the oil pump, passageways, and oil pan.
High mileage engines have two problems: they guzzle fuel with an insatiable appetite, and they’re quite inefficient when it comes to oil.
Lubegard 98901 does a thorough job of cleaning the engine which gives the new engine oil an extra 30% of life. You won’t need to change the oil that frequently because it won’t get dirty inside the engine that quickly.
Lubegard 95030 Engine Flush
The third and last entry from Lubegard on this list is all about engine flush. You use it before you change the oil in your gas or diesel engine to cleanse the internal parts of the engine and ensure the oil gives you more mileage.
Because combustion inside the engine tends to leave residue and by-products which if left on their own will reduce the performance and life of the engine, it’s important to get rid of them on a regular basis.
Lubegard Engine Flush has a unique mixture of dispersants and detergents that work on the most difficult gunk, break it down, and flush it out.
Most high-end synthetic oil contains detergents and dispersants. These aim to prevent small particles from sticking to the surface of the engine and the passageways. But they’re not as effective when the engine is full of contaminants.
But that’s not all. Because the engine is already dirty, all new oil you put in there becomes dirty quickly. This means you need to change the oil more often.
The premium synthetic blend in Lubegard 95030 cleanses the engine and makes the engine oil work more effectively.
If you have a flush machine then flushing your engine is as simple as following the instructions on the machine.
Without a flush machine, you put your engine to idle and while it’s warm add the engine flush. Let it run for 5 to 10 minutes also on idle. Then drain the engine flush allowing it enough time to drain. When the engine is clean, replace the oil filter and add the engine oil. It doesn’t get any simpler, really.
Niteo Motor Medic MFD1 Synthetic Motor Flush
Here’s another product from Niteo, that is also an engine flush, but this one targets obstinate gunk. Niteo Motor Medic MFD1 is for diesel and turbocharged engines.
That doesn’t mean it won’t work on gasoline engines, because it certainly does. But the idea is those heavy-duty engines which see their fair share of extreme weather, pollutants, and tough driving condition need something extra strong to flush all the gunk out.
And that’s exactly what Niteo Motor Medic MFD1 does. And it does it with efficiency and accuracy that is both admirable and satisfying.
You use this engine flush before you change your engine oil. And thanks to its speed and strength, every new oil change removes more of the gunk inside the engine and allows the oil to reach all the parts of the engine.
But there’s more. Since Niteo Motor Medic MFD1 takes it as a personal challenge to unseat that adamant gunk that has been blocking your oil pan and oil pump, you just can’t wait for the next oil change to apply the engine flush and chisel at the hardened gunk in there.
After a few applications, your engine will be spotlessly clean.
We mentioned how Niteo Motor Medic MF3 was a good choice if you had a gasoline or non-turbo engine. And while it still works for turbo and diesel engines, it is recommended to use Niteo Motor Medic MFD1 instead.
Now, both of the Niteo products only need 5 minutes to work their magic and destroy the clusters of contaminants in the engine. So remember not to keep the engine flush inside for longer than 5 minutes.
Sea Foam takes a more targeted approach toward tackling the problem of gunk and blockages inside your engine. And it’s a refreshing change from the other engine flush products on the market.
And depending on your school of thought, you might appreciate a targeted approach as more effective as opposed to a general application of the engine flush. But, on the other hand, other car owners might disagree.
So it all comes down to your personal preference really. The jury is out, and the verdict is mixed. Should we go for a mistrial or would you rather try it out for yourself and be your own judge?
So what are those specific targets that Sea Foam deals with? For starters, the engine flush focuses on carb jets, injectors, and passageways. It also takes care of pistons, intake valves, and cylinders.
And while it’s there, it turns to the VVT actuators and timing chain tensioners to make sure everything is shipshape. It then polishes everything off with a thorough dissolving of the oil residue in the crankcase.
When all looks good, Sea Foam then turns to the fuel systems and gives them a good dust up to make sure no fuel residue still lingers.
With its simplicity, this kit makes it much easier to clean your engine. The targeted approach also has an overall positive effect on the performance of the engine. You’ll notice how the engine is less noisy and seems to have regained some of its original power.
In all fairness, if your engine has high mileage and tends to die out when you least expect it, then a dash of Sea Foam before you change your engine oil will give it a new lease of life.
Lubro Moly Proline Engine Flush
Lubro Moly Proline Engine Flush is the new kid on the engine flush block. But just because it’s new doesn’t necessarily make it any better or worse than the other entries on this list.
The real factor here is how good, or bad does it tackle the problem it was made to solve — namely the problem of residues and contaminants.
Now, it’s important to point out that Lubro Moly Proline takes a dual approach to the problem of flushing your engine. It doesn’t just kick out gunk, but also protect metal surfaces from corrosion.
While this dual approach is not unique to Lubro Moly Proline, it really makes it a good contender for the title of the best engine flush. A decision we’re trying to reach here and which you’ll find at the end of the article.
It actually feels like you’ve got your money’s worth when the engine flush offers to go out of its way and do something you weren’t expecting. Like, say, protecting the metal surface of the engine from rust and corrosion. But is that good enough to crown it as the winner of our list?
And by being environment-friendly, we don’t mean that Lubro Moly Proline does a good job cleaning the engine which somehow makes the environment a better place to live in. Well, it does, but so do the others as well.
What we really mean here is that the ingredients of Lubro Moly Proline do not pollute the environment. When you eventually dispose of the engine flush, it won’t pollute the environment.
Prolong Super Lubricants PSL11000
The last entry on this list, Prolong Super Lubricants PSL11000, uses advanced technology to bring about heat reduction as well as minimizing friction inside the engine. Dubbed AFMTTM which is short for Anti-Friction Metal Treatment.
The idea is, by reducing both the heat and friction inside the engine, your engine oil tends to last longer, and the engine performance improves.
So even if you’re running low on oil or coolant, your engine will not heat up, and you can make it safely home where you can replenish your engine oil.
Of course, using an enhanced lubricant like Prolong is not recommended for brand new cars. You need to wait until the cylinders have married to the rings and the engine “rested” as they say.
But once your car has passed that stage, you can go on and use Prolong. Many car owners swear by the lubricant in this product and how the anti-friction has given the engine an extended life.
And you’ll notice it in how little repair work would need to be done to the car. Just make sure to use a 10% concentration.
Since it’s easy to use, you’ll notice the results early on. There’s no room to make mistakes here. Just pour the lubricant into the engine crankcase and let the anti-friction get the job done. You can apply it with every oil change, every 6,000 miles, or every six months.
