BG 44K

If you’re not a car enthusiast, you might never heard of a fuel system cleaner. The only thing you might be aware of when it comes to maintenance is changing your oil and keeping the tire pressure at the right amount.

Fuel system cleaners can and should be integral parts of taking care of your vehicle. You won’t have to use them as often as you should be getting your oil change, but it’s important to know what they area.

Those that are car enthusiasts, however, will certainly recognize the BG brand. They’re one of the most well-known brands in the world when it comes to fuel products and equipment. Their products proudly claim to improve your car or truck’s overall performance as well as gas mileage, but can they live up to the hype?

In order to help you answer that question, we’ve gone through the ingredients list of the BG 44K system as well as outlined the pros and cons for you on this guide.

BG 44K Overview

Before we go through everything, let’s go ahead and start with the basics. Just what is BG 44K and what purpose does it serve?

The technical name for the BG 44K is a fuel injector or system cleaner. In the bottle (assuming you clicked on the product description above), you’ll see that it comes in a size of 11 ounces. These 11 ounces contain high-quality solvents and various additives that go into a vehicle’s gas tank.

There are a few harsh chemicals in the product, they are non-corrosive and 100% safe for your car engine. All of these products together are supposed to help improve gas mileage as well as your vehicle’s performance.

The most interesting thing, in our opinion, is the fact that this fuel system cleaner doesn’t use any alcohol but instead relies on the most basic and simple ingredients. In theory, this means that the cleaner is much more efficient at removing harmful buildup that occurs in the engine that its alcohol-based counterparts.

With its blend of ingredients and additives, the BG 44K is fantastic at cleaning up carbon deposits, ethanol, and moisture from the fuel system, all of which can be harmful to your overall system. Removing these will help restore the vehicle’s original functionality. Plus, BG markets this product as being able to increase your vehicle’s power output and be helpful at reducing exhaust emissions.

But can all of this really come in such a small package? Can BG live up to the hype? Before we answer that question, let’s go over all the benefits again:

  • Improved fuel efficiency
  • Replenished vehicle performance
  • Cleaner fuel system
  • Decreased exhaust emissions
  • Boosted power output

It almost seems too good to be true, especially when reading through the list of benefits. Let’s take a closer look and see if it does what it says it does.



When talking about the difference of fuel over the years, it’s no secret that the fuel of today is chemically less stable than it was just a few decades ago. You’ll find low-quality fuel at just about any pump today and the price usually doesn’t make a difference. If you’re someone that drives a car and, naturally, has to fill up on a regular basis then it’s 100% guarantee that you have used this fuel.

The low-quality fuel is going to cause deposit buildup along your fuel injectors, pistons, carburetors and through the entirety of the combustion chamber. This is largely natural but if left unchecked over time, you’re going to notice a loss of engine performance, more difficult starts, less efficient gas mileage, and increased emissions.

So what do you, as an average everyday consumer, do here? Do you just accept a loss of vehicle performance and call it a day?

That’s why BG made this fuel system cleaner, to help people like you regain some of their vehicle’s lost efficiency.

We’re happy to say that this product does exactly what it says it’s supposed to do. Thanks to its unique combination of chemicals, BG 44K goes a long way in eliminating carbon deposits around the combustion chamber and buildup around the rest of your vehicle. If used regularly and correctly, it’s going to clean up the entire fuel system.

The best part about everything is that it’s very affordable and incredibly easy to use. All you have to do is pour it right into your gas chamber and that’s it. There are no special mixtures to follow, steps to take, or anything else. It’s all that easy. You can say goodbye to those harmful deposits and other buildup around your combustion chamber.

The 11-ounce canister is able to treat up to 20 gallons of gasoline making it an absolute bargain.

So,here is a summary of those key features.

  • Improved vehicle performance
  • Affordable
  • Easy to use
  • Reduced emissions
  • Cleans the entire fuel system


How Does it Work?

As with all fuel system cleaners out there, the ingredients in BG 44K contain ingredients that will allow it to remove or flush out those harmful deposits and buildups around your fuel system.

Where do these deposits and buildups even come from though?

Since modern gasoline is made using ethanol to act as an octane-boosting ingredient, it’s going to oxidize and emulsify over time, leaving behind these horrible buildups and deposits. These deposits cannot be burned through with normal combustion.

But just as Billy Mays said, “But wait, there’s more!â€

In addition to the buildups due to ethanol, there is also moisture that accumulates because of the ethanol. This contributes to corrosion and gunk in and around the metal and rubber parts of the gas tank. As you can probably guess, this leads to poor performance with your vehicle.

BG 44K has plenty of solvents and additives that bond with all that buildup and gunk to deteriorate it to where it will eventually be flushed out of your system. It’s really that simple.

The easiest thing to do is think of your car’s engine like an oven. For any of us that have been in the kitchen for quite some time, you know that your oven needs regular cleaning. Sure, baking the occasional pizza in there isn’t going to do a lot, but meal after meal isn’t going to do your oven any favors.

Cheese boils over, the pizza falls in half, or you burn your meal (who isn’t guilty of that?). Eventually, you’re going to notice lots of grime and nastiness inside your oven. Using old-fashioned water and soap is more likely to spread the dirt around instead of actually cleaning it, which is why you need to buy a special product to clean the inside of your oven.

If you neglect to clean the inside of your oven, that could cause issues down the road, effecting your oven’s cooking ability or worse, causing some kind of fire.

Your car’s fuel system is just like this. There probably isn’t much gunk or buildup at first, but over time there is bound to be more and more which is why you need to clean it out with a good fuel system cleaner.

Pros and Cons of BG 44K

We can’t go through a product like this without mentioning the pros and cons and we know how necessary they are for the average consumer.


Cleans the Entire Fuel System

With its unique combination of ingredients, the BG 44K is going to do a fantastic job of cleaning out your entire system. Nothing is safe from its cleanliness, including the pistons, carburetors, fuel injectors, and just about everything else you can think of.

It’s incredibly vital that the fuel clean make sure and clean the pistons which are not something that every fuel clean is able to do. Thanks to this, there is a bigger uptick in overall vehicle performance and fuel efficiency.


Helps Condition the Fuel System

Walk into a locker room and it smells like feet. Walk into your teenage son’s room and it smells like…a whole host of smells. Walk into a garage and it smells like gasoline and grime. While BG 44K may not be able to help you with locker rooms or your child’s room, it’s going to help you with your garage.

By cleaning the fuel system, it also does a wonderful job of conditioning it. This means that it’s going to make sure and leave a pleasant scent in your engine, something that many other fuel cleaners don’t do.


Better Fuel Economy

We’ve touched on this a number of times, but in a world of ever-rising gas prices, it’s always a good idea to remind you that your fuel economy is only going to improve with the BG 44K. You’re going to have to use it on a regular basis to see the changes, though.



Not an Aggressive Cleaner

No, we don’t mean something like Mr. Clean on a mean streak, but something a bit different. If you’ve never used a cleaner over the life of your vehicle and there are tons of buildup in your fuel system, BG 44K isn’t going to fix all those issues.

It’s simply not powerful enough to fix long-term buildup and grime. If your vehicle wasn’t properly cared for, then it might need replacing.


Conditioning effects need multiple uses

For those looking for that pleasant engine smell, you’re not likely to notice it after just one use. Heck, you’re not likely to notice it after two uses. We found that you have to use the cleaner multiple times in order to take that smell in.

If your vehicle hasn’t been cared for in quite some time and there is buildup everywhere, then you may never notice the pleasant smell in your garage.


Ingredients of 44K

Just like any good cake, you need top-quality ingredients for an effective fuel cleaner. We have the ingredients listed below for you:

  • Naptha (petroleum), hydrotreated heavy, 15-40% (CAS number 64742-48-9)
  • Stoddard solvent, 10-30% (CAS number 8052-41-3)
  • Solvent Naptha (petroleum), light aroma, 1-5% (CAS number 64742-95-6)
  • 1,2,4-trimethyl benzene, 0.5-1.5% (CAS number 95-63-6)
  • Ethylbenzene, 0.1-1% (CAS number 100-41-4)

As we talked about before, there are plenty of solvents but you won’t find any alcohol in this cleaner. The Flash Naphtha (cool superhero name) is actually a slow-evaporating aromatic used as a retarder. A retarder is an ingredient that improves the flow of other chemicals which in this case are fuel, oil, and moisture.

This ingredient is able to break down those carbon deposits, making it doubly important to your vehicle’s overall functions.


Closing Thoughts

Overall, we are incredibly happy with this product. It does wonders for your fuel system, cleaning it out while also improving overall performance. With regular use, you’re going to keep a more efficient system and have an improved fuel economy.

As a special note, this isn’t for diesel engines but don’t worry, BG also has a product for you. We hope all this helps!
