Should You Use Fuel Additives for Your Vehicle?

They're called different names: gasoline additives, fuel treatments, fuel additives, or gas treatments, but their purpose remains the same: to improve your vehicle’s engine performance.

Should you use fuel treatments for your engine?

You don't really need fuel additives if your car’s new (or comes with a new engine). This also goes for used vehicles that are well-maintained and in good working condition.

However, if your car has been badly maintained, old, often driven, or neglected, then fuel additives might help. Truth is, many don't really show noticeable improvements, especially if you choose the all-in-one types that claim to work on almost everything on your engine.

Choose specialized fuel additives

You'll have better chances here if you choose specific, good-quality fuel additives that are designed to work on one problem only. These are the ones you should be looking out for.

For instance, if you want a fuel treatment that can prevent gas separation and engine corrosion (especially if your vehicle has been idle for a long time), then choose Fuel Stabilizers.

If you need/want an additive that can lessen hard starting, something that will unclog your vehicle's diesel fuel filters especially when it's cold, then go for Anti-Gel Diesel Additives. 

If you want a treatment that will protect (and prevent) your fuel injectors from sticking together, then go with Fuel Injector Cleaners.

If you want an additive that can increase your vehicle's fuel octane rating as they lubricate the valves, then go for Octane Boosters. 

Choosing specialized gas treatments like these are far more effective than those one-size, do-it-all treatments found in the market today. Just make sure to follow the directions carefully, put only the recommended amount in the tank--and check your vehicle's manual when in doubt. It's also important to pour them in when you are in the process of filling up your tank--not when it's empty.

Beware those that claim they can increase gas mileage

Some treatments claim to significantly improve your vehicle's fuel mileage. They say they can turn water into gas, or mix in enhancers, but this is mostly just fiction.

These types don't really improve fuel efficiency. The very least they can do is to clean the engine so thoroughly that they remove all the gunk that's clogging it. This helps the engine perform the way it's supposed to, thereby improving fuel efficiency in the process. 

Final Word

Use fuel additives with care--not all are what they claim to be. We even suggest that you remain cautious even if you're using the specialized additives we recommended earlier.

Truth is, all fuel treatments pale in comparison for proper and consistent engine maintenance. Often, these chemicals's effectivity are just a result of having a fuel-efficient car in the first place--and/or a smart, driver who already knows how to save up on fuel. Both are far more effective than what these additives claim in their advertisements.

So the best thing you can do is to save the money you use to purchase another bottle, and just use it to pay for your vehicle's next service check. And follow the maintenance schedule religiously as well. These would do you a lot of good than adding chemicals that your vehicle may not need in the first place.
