Product Overview: best way to flush engine oil
If you visit a garage for your regular oil change, you’ll have heard an engine flush pitch. It’s easy to think engine flushes are simply an upsell, but these powerful little cleaners can breathe some new life into an older vehicle! Simply put, an engine flush product is a chemical that’s added to your engine. This chemical is designed to remove sludge and deposits that commonly build up in engines over time. Below we are giving a trusted engine flush review for you!
Our Picks of The 6 Best Engine Flush Review
1. Niteo Motor Medic MF3-12PK 5-Minute Motor Flush
This is a highly recommended engine flush product from the Niteo. It is completely liquid just like gasoline. This feature has made this engine flush eligible for almost all types of vehicles. The biggest plus of this engine flush is that it takes only five minutes to flush out engine-destroying sludge, deposits, and contaminants that decrease the power and efficiency of the engine.
It also removes accumulated gums, varnishes, and sludge from internal engine parts and releases sticky valves and piston rings. In the process, it allows oil to circulate freely to all parts of the motor. Thus, helps your motor run smoothly. Even more, it frees up sludge associated with slow city driving. This engine flush helps restore your vehicle’s lost performance to a greater extent.
In addition, it also remarkably increases the longevity of your engine. Motor Medic Motor Flush (MF3) is the perfect solution for improved performance for any non-turbo gasoline engine. But, if you have a diesel or turbocharged engine, use Motor Medic’s Synthetic Motor Flush (MFD1). Use it before every oil change. But, remember that it should be used when your engine is cool. It always works best on cold engines.
- Cleans engine in 5 Minutes
- Increases operating efficiency of the engine
- Removes gum, varnish, sludge
- Frees sticky valves, piston rings, and lifters
- Improves oil circulation
- Offers the same results as advertised

2. LUBEGARD Engine Flush – best engine flush cleaner
Kicking off our top five reviews, we have LUBEGARD’s Engine Flush. Considered a staple in garages across the country, this American-born company is a fan favorite. Most notably, LUBEGARD is one of the most popular companies to offer a low-solvent formula. While every engine flush will contain some type of solvent, LUBEGARD offers a conditioning formula that’s perfect for skeptical users.
What We Liked:
LUBEGARD’s LXE technology is one of the few blends that contain no harmful solvents. Their formula is focused on special detergents that will not harm seals or gaskets. The conditioning elements of this flush are actually beneficial for rubber components. Improved fuel efficiency. While this is a claim many engine flushes will claim, it’s great to see reviews for this product match the promise. For those who are looking specifically to improve the fuel efficiency of their vehicle, LUBEGARD is a serious contender.
This engine flush is also available in a fantastic package. At most points of purchase, you’ll be able to pick up LUBEGARD Engine Flush in a combo pack with their BIO Tech Engine Protectant. If you’re looking to give your engine the full treatment, this is a simple, cost-effective way to get started.
What We Would Change:
It’s important to note that due to the lack of solvents, you may not get the same clean you would with other brands. This is great for a first-time user, but if you’re completing a flush on a vehicle with more sludge (or even a used car that may not have been maintained), you may want to look for something a little heavier duty.
3. AMSOIL Engine and Transmission Flush
With forty years of experience making synthetic lubricants, AMSOIL may be one of the first products you think of for a gentle cleaner. While AMSOIL Engine and Transmission Flush is a great cleaner choice, it’s important to note that a recent formula change has made this flush a little less solvent heavy. This change makes the cleaner a great middle-of-the-road product for those looking for a seal-friendly but powerful cleaner— just make sure you get the newer multi-purpose flush instead of the stronger engine only flush!
What We Liked:
Because this product works on both gasoline and diesel engines, this is a great product to keep on hand. Affordability. When compared to other engine flushes, AMSOIL Engine Flush oil definitely gives you the best bang for your buck. This affordable alternative is a great entry point for someone who’s not willing to spend much money on flushes but still want to get a quality clean.
The clear instructions on the bottle make both engine and transmission flush a breeze.
What We Would Change:
As we mentioned, a recent formula change took AMSOIL Engine Flush from a solvent cleaner to a detergent-based cleaner. While this means it will be gentler on your vehicle, it also means it will not be as heavy duty as some users need.
4. Liqui Moly 2037 Pro-Line Engine Flush
If you’re looking for a product with a cult following, Liqui Moly may be your best bet. With a company originally formed in Germany, this engine cleaner is from their professional line and is often used in garages that offer engine flushes. This formula is advertised to be gentler than most, which is going to give first-time users a bit of peace of mind. At the time of this article, this Liqui Moly product has over 200 positive reviews on Amazon, and that number shows no signs of stopping. This is the top reviewed engine flush available on the market. Majority of customers report being able to remove near-black oil from their vehicle once they do drain the oil, giving us undoubtedly proof that this product has earned every one of its glowing reviews.
What We Liked:
Features a seal-friendly formula. Perfect for a quick clean. This formula requires your engine to idle for only 10 minutes before completing a flush. Can be used for all vehicles in your house— this formula works for all 4-stroke gas and diesel engines!
What We Would Change:
Depending on where you buy it, it can run a bit more expensive than other brands on the market. While most reviews are positive, there are a few who claim that they needed a deeper clean for their engine. As we mentioned with the LUBEGARD Engine Flush, this may be more of a maintenance product than an in-depth engine flush for a used car.
5. Motor Medic by Gunk MFD1 – Top Rated Engine Flush Product
If you’re looking for a powerful, solvent-focused cleaner, Motor Medic has you covered. This company joined the automotive industry in 1958 and hasn’t let us down since! With a full line of successful automotive fluids, their engine flush easily makes our list. This cleaner is available in two different options: The MF3 and the MFD1. While both are amazing products, we’ve opted for the MFD1 model, simply because of the added lubrication. With a strong solvent like Motor Medic, you’ll want to make sure you add a bit of extra lubrication to your engine.
What We Liked:
Motor Medic by Gunk MFD1 clocks in as one of the fastest engine flushes available on the market. While others require you to idle for 15 minutes (or drive with the solvent injected), Motor Medic recommends you keep the solution in your engine for a maximum of 5 minutes. As opposed to the MF3, the MFD1 Engine Flush cleaner can be used on diesel and turbocharged engines, making this an incredibly diverse product. Setting it apart from its competitors, Motor Medic offers additional lubrication and anti-wear additives to keep your vehicle running smoother for longer.
What We Would Change:
While not typically advertised online, it is important to note that Motor Medic has additional requirements for older vehicles. In vehicles over 75,000 miles, it’s advised that you drop the pan while you do your oil change— something which may turn off some drivers.
6. Sea Foam Motor Tune Up
If you’re looking for a Goldilocks product, Sea Foam may be your new best friend in the garage. Originally, this company specialized in boat motors, but Sea Foam quickly found its place in the automotive market with its superior quality products. While Sea Foam Motor Tune Up is marketed as an engine cleaner, it also makes for a fantastic fuel injector cleaner, lubricant, stabilizer and moisture controller. That being said, you won’t get the same clean with this jack-of-all-trades cleaner as you will with specially made engine flushes.
What We Liked:
Because this cleaner is safe for gasoline and diesel engines, this product is made even more diverse. No cleaner mentioned on this list is as versatile as Sea Foam. If you’re trying to reduce clutter, Sea Foam is a no-brainer. With a decent price point and bulk options, Sea Foam is a fantastic automotive cleaner to keep around the garage.
If you haven’t used an engine flush product before, one of the most appealing things about Sea Foam is the superior customer service. From order to use, this company is known for offering their customers fantastic support.
What We Would Change:
While we love the multi-use function, it’s a double-edged blade. Sea Foam is simply not going to cut it when compared to something harsher. If you need a deep clean, you’ll have to look elsewhere.
Why Should I use an Engine Flush?
Ideally, a proper engine flush product will eliminate any buildup in your engine and return your engine to its former efficiency. When sludge and debris build up in your vehicle, it can clog screens or oil passages within your engine which, in turn, will restrict oil flow. Over time, you will notice a decrease in horsepower, something which may be attributed to pesky deposits causing rings to stick. Sludge can form in your engine for multiple reasons and is largely considered regular wear and tear. For the most part, debris and sludge forms for a variety of reasons, such as:
Frequent short trips. If you do a lot of local city driving, you’re more likely to get a buildup. This is because small trips don’t allow the oil to head up and evaporate moisture properly.
High levels of heat.
While things such as regular oil changes and a quality oil can help reduce the amount of buildup in your engine, it’s still a great idea to run an engine flush through occasionally.
How Do I Know I Need an Engine Flush?
If you meet some of the criteria mentioned above, you may need a regular engine flush. For those who are curious as to the amount of sludge that is currently built up in their engine, there are a few areas you can check:
The simplest way to check for sludge is to see if your dashboard lights are on! If the check engine light is on, this is a possible clue that you may have a sludge buildup. Similarly, if your oil change notification light is coming on sooner than expected, you may have a sludge problem.
The next time your vehicle is off, simply try taking a look under the hood. Firstly, you’ll want to check for signs of oil splatter or engine sludge.
If you’re willing to get down and dirty, check the oil pan for sightings of sludge. Remove the oil cap from your pan and take a look inside— remember to use a flashlight if necessary. If there’s even the slightest sign of sludge in the pan, you can expect to find significantly more in the engine itself.
How Do I Get The Best Engine Flush Cleaner?
If you’re someone who regularly changes their oil at home, engine flushes are completed in just a few extra steps. Once you’ve selected the engine flush that’s best for you, you’ll add the solution into your car’s oil-filler port. From here, it’s just a matter of idling your engine for the recommended time (usually, 15 minutes). Then, you’ll drain your oil, change out your old oil filter, and add in fresh oil. It’s vital that you drain and replace the oil after an engine flush—otherwise, your engine may plug with the very debris you were trying to remove.
Remember: Each engine flush will have slightly different instructions, and it’s important to consult each product individually.
Purchasing Tips and Buying Guide – best way to flush engine oil
If you’ve never bought an engine flush before, it can be tricky to know what to look for. When you first face the automotive aisle, you’ll come face-to-face with dozens of competitors. Don’t get intimidated just yet! Selecting the best engine flush comes down to considering just a few simple things. Firstly, you’ll have to know some specifics about your car before heading into your auto shop. For example:
Do you use diesel? For those who are looking to flush a diesel engine, it’s important to know that you’ll have to buy a specific engine flush— not every cleaner is meant for both gasoline and diesel engines. Keep an eye out for diesel compatible flushes when you go shopping.
Do you need a solvent? If you’re worried about your car’s seals, you may want to pay special attention to the type of engine flush your using. Companies like Liqui Moly advertise that their engine flush does not attack seals. Others advertise to use little to no solvents in their engine flushes.
What type of motor oil are you using? You’ll want to make sure that the engine flush oil you buy is compatible with your preferred type of oil. If you’re unsure, stick to flushes that are compatible with all commercially motor oils commercially available.
What is your price point? For those looking to keep the price low, you’ll want to keep an eye not only on the price tag but also the number of typical uses. While some offer multiple uses with one container, most are a single application.
Do you want a full system? For those who are looking to do a deep clean, it may be worth looking into a full system. Many of the top-rated engine flushes recommend special oil or additives you can use to give your vehicle the extra boost it needs. If you’re looking to give your vehicle the full treatment, keep an eye out for bundles, such as the one offered by LUBEGARD.
Remember that an engine flush isn’t something you’ll want to rush into. Deciding on the best product for you is important, and once you know what you’re looking for, you’ll be able to make the right decision.
