Should You Use Fuel Additive?

Should You Use Fuel Additive?

No matter what truck you drive, you want it to run efficiently when towing. Many truck owners turn to fuel additives to help give their vehicles an extra boost.

However, do these products work as well as their labels state? Should you use a fuel additive when towing? 

Today, we’re taking a deep dive into fuel additives, how they work, the benefits of using them, and if they’re right for you. Let’s get started.

What Is Fuel Additive?

A fuel additive is a product you can add to your fuel tank to increase performance or extend the life of your fuel. Additives lubricate and protect the sensitive components in your fuel system. They keep carbon and other deposits from building up on your fuel injectors, carburetor, intake valves, and in your fuel pump.

Pro Tip: Here’s our favorite fuel additive.

When all system components work smoothly, you can expect better performance and fuel economy. You increase the chances that you’ll keep your vehicle out of the repair shop and have more money in your pocket.

Fuel stabilizers are also additives. You typically add these products to gas that will sit for an extended time. Stabilizers extend the life of fuel. They can help prevent it from evaporating, breaking down, and causing issues in whatever fuel system you put it in later. 

A fuel stabilizer isn’t necessary for vehicles or equipment used regularly. The fuel likely won’t sit long enough to cause any issues. 

However,  it is a good idea to add a stabilizer to fuel sitting in gas cans or equipment’s gas tanks for months at a time. This helps ensure you don’t experience any issues the next time you use it.

Does Fuel Additive Really Work?

Fuel additives do work. However, you likely won’t notice results immediately. Regular use is the key to getting the most out of it. 

The additive breaks down the gunk that attaches to the sensitive components in your vehicle’s fuel system. The chemicals will then prevent deposits from building up in the future.

You can dump the fuel additive directly into your fuel tank the next time you fill up your tank. However, make sure you read the directions if you get a multi-use bottle to avoid putting too much in. The additive can take some time to work its way through and clean your fuel system.

This product also works to prevent issues down the road. Avoiding expensive repairs means keeping your truck out of the shop and saving you money.

Which Fuel Additive Is Best? 

You want to do your research before adding products to your fuel tank. The best fuel additive will be budget-friendly, easy to use, efficient, and positive user reviews. Several brands stand out from the rest.

One of the best on the market is BG 44k Fuel System Cleaner. This is a great option for those looking to restore their system after years of use or increase the vehicle’s power output. 

One Amazon reviewer says, “I noticed much better performance in the drive. The throttle is now lively and even punchy.” This is one of the highest recommended cleaners from users and automotive professionals. 

A standard container of this product has 11 oz, which can treat 20 gallons of fuel. So depending on the size of your fuel tank, you may get a couple of uses out of it. Each container typically costs $25 to $30. However, the results are worth every penny.

Lucas Oil is another well-known brand in the automotive industry. For less than $30, you can get one gallon of their fuel treatment. This is enough to treat over 400 gallons for vehicles and other gas or diesel engines.

Should You Use Fuel Additive When Towing?

Towing puts your engine and other essential components to the test. You want them to run smoothly and efficiently. If you tow regularly, a fuel additive can significantly help. Many RVers have noticed improvements in performance and efficiency.

However, just because others do it doesn’t mean you should too. Check your owner’s manual or consult your manufacturer. You don’t want to dump something they don’t recommend into your fuel system. Give them a call and see what they recommend for your specific vehicle when in doubt.

What Are the Benefits of Fuel Additives? 

Fuel additives help keep the critical components inside your vehicle’s fuel system clean. Small particles and other gunk can gather and clog them up. 

These clogs cause the system to run inconsistently and inefficiently. You’ll experience better miles per gallon, better acceleration, and help avoid costly repairs.

Can Fuel Additives Damage Your Engine?

Fuel additives can do a lot of good. However, overusing them can cause issues for sensors and various components in your system. Over time, if the additives contain corrosive agents, they can eat away at the lining of the fuel pump and other parts.

Typically, most users who experience issues overuse them. Ensure you follow the directions and consult a trusted mechanic to avoid causing more harm than good.

It’s also a good idea to check your owner’s manual. Your vehicle manufacturer may discourage the use of some products. If they discourage using a product, you could void a warranty. You don’t want to get stuck with a hefty repair bill that could have fallen under warranty coverage.

Pro Tip: Preventing damage on your vehicle is crucial! If you’re Overlooking a Damaged Fuel Pump on Your Vehicle you can quickly find yourself in a pickle! We uncovered how to avoid it.

How Do You Get the Best Gas Mileage When Towing? 

Fuel additives are a great way to keep your vehicle running in optimum condition. They’ll keep your fuel system clean and free of any gunk that can build up and cause issues. Using BG 44k or a fuel additive from Lucas Oil can keep your vehicle running efficiently and provide great results. 

While additives can help protect your engine, you can find better ways to improve your gas mileage. How you drive can play a significant part in your fuel efficiency. No magical additive can counteract inefficient driving habits.

Too fast and hard accelerations waste a lot of gas. So drive responsibility and watch your speed, and you can watch those MPGs climb.

I have been using amsoil products for several years. I have found that what amsoil proclaims about their products are true. I do believe in them very strongly and here is why: first, they offer different grades of their engine oil such as one will give an owner. the choice between 12,000 mile oil change and 25,000 mile oil change. I had a Dodge 2500 four wheel drive with a diesel 5.9 engine. I have now no reason to have a truck of that size due to my eighty years. However four or five years before I sold it I wanted to see for myself if it would live up to amsoil claims. I was using the 25,000 mile oil grade And I drove the beast three years and seven month while not reaching my 25,000 miles on the oil and I begin to feel sorry for my old faithful Dodge. At such time I changed the oil with NO damage. I have heard all of my life of an old saying, the proff is in the pudding. Nuff said! P.S. the oil instructions say 12,000 miles or one year and same for the 25,000 oil. However due to my test, I think the added one year part is to keep out of a law suit. You be the judge.

Hydrotex Power Kleen and Essentialube. I was going to replace the injectors because of carbon and varnish build up. After 235k I figured it was time. Started using these and my 7.3 was whipped back into shape and preforming like it had 100k less miles.

With todays engines being turbo charged fuel additives should avoided. Fuel additives generally cause the engine to run hotter and thus the exhaust gas temperature is also higher and that can damage the turbo charger per several mechanics I know and articles I have read. I have a new F150 with the turbo charged V6 pulling a TT at 5200 lbs. My older F150 with the same engine, trany and rear end (10 speed/3:55) ran just fine pulling the same TT without having to resort to additives. Normal maintenance routines kept the power train in good condition without adding additives and my gas milage was outstanding; generally, around 12-14 mpg overall pulling the TT at highway speeds (65-70 mph). I believe good consistent maintenance is better than additives.

You kept referring to gas for a fuel additive I am assuming that you meant gasoline! You did not mention any fuel additives for diesel engines!
