Best Diesel Additives Buying Guide & FAQ
Things to Consider When Buying Diesel Additives
There are a lot of diesel fuel additives in the market and it can be particularly dizzying if you’re not sure what to get in the first place. As such, even before you start shopping for the best diesel fuel additive make sure you understand some factors that should be carefully considered.
- Type of Additive
This is related to what you want to achieve by using a fuel additive into your car’s system. There are a variety of fuel additives that can have different functions so it is best to list first what you want to achieve and then look for a specific type of fuel additive that can best help you achieve your goal.
- Treatment Rate
Some products require fuel treatment every time you top up your fuel. Other products will only require periodic treatments, often at regular intervals. Your choice obviously depends on what is convenient for you – treating your fuel every time you top up or treating it every once in a while. There are benefits to every-refuel treatments as you’ll never miss a regimen. The problem is that it can be quite costly. If you go for period treatments, the issue is that you might forget putting the additive.
Everyone today is already conscious about the impact of fuel emissions on the environment. And while oil producers are complying with environmental regulations, the fuel additive you use should also not undermine these efforts by fuel manufacturers. Read the label very well and check if there are harmful chemicals that can have a negative effect on the environment.
We mentioned something about fuel additives being of different types, each with its own purpose or function. In choosing a fuel additive, it is always better to go for a product that can perform a multitude of functions to give you the best value. For example, if a product can protect your engine and fuel system while also stabilizing your diesel fuel and boosting your fuel’s cetane rating, then it is way better than a product that will only boost your cetane rating.
- Vehicle Appropriateness
Always check if the fuel additive you want to use is compatible with the engine and fuel system in your car. There are products that are more specific to certain types of diesel engines and fuel systems while there are also those that are for general use.
Benefits of Using Fuel Additive
Fuel additives can improve the performance of your diesel engine by making it more efficient when it comes to engine burns. Each stroke of the pistons can deliver the kind of power that one needs from their ride.
Using fuel additives can also help improve fuel economy which can literally translate to better savings on fuel. Instead of refueling more frequently, you’d top up your fuel less often because of the improvement in engine performance and efficiency.
Manufacturers of fuel additives also make sure that their products will not harm the environment. Many are designed to improve the environmental-friendliness of already-eco-friendly modern diesel vehicles.
You are also protecting the different components of your car’s fuel delivery system from the pump to the fuel line and the fuel injectors as well as other related parts. Fuel additives can improve the lubricating efficiency of diesel so these parts are adequately protected.
Treating your vehicle with a fuel additive is also more cost-effective than bringing it to the shop and having a professional do it for you. Virtually anyone who knows how to open the fuel tank lid in his or her vehicle can easily pour a fuel additive.
Types of Fuel Additive
One of the most important factors to consider when picking a fuel additive for your diesel engine is the type of additive. Currently, there are four types of diesel fuel additives.
- Cetane Boosters
This is almost the equivalent of the octane rating in gasoline. The cetane rating of diesel fuel accounts for its combustibility. The higher the cetane rating, the more efficient is the diesel engine. Boosting the cetane rating of diesel fuel can, thus, give you the engine performance you need.
- Fuel Stabilizers
These help improve the efficiency of diesel fuel while also preventing hard starts. These are generally included when the car’s engine and fuel system are in a state of disuse, still allowing for the efficient use of the energy stored in diesel fuel.
- Anti-gel Additives
For those living in colder regions, there’s a tendency for the diesel fuel filter to get clogged when paraffin wax or gel inadvertently forms in the diesel fuel. Although modern diesel cars now come with heated fuel filters and fuel lines, anti-gel additives can still serve to improve the vehicle’s cold-starting performance, especially in extremely cold temperatures.
- Fuel Injector Cleaners
If you’re experiencing sluggish acceleration, hard-starting, or even poor engine performance in cold weather, you may want to use fuel additives with injector cleaners. These can help remove deposits that may already be clogging your car’s injector nozzles. Some high-end fuel additives can even clean other parts of the engine.
How Diesel and Gasoline Differ
There really isn’t that much difference between diesel and gasoline since both are made from crude oil that underwent a series of refinement. Crude oil undergoes several stages of distillation that separates the various hydrocarbon molecules that are present in crude oil. Gases are the first to be separated followed by solvents. Moderately-light hydrocarbon chains are next to be separated. When these are blended, you have your gasoline. As the crude oil is kept on being distilled, heavier-chained hydrocarbons are also separated. After gasoline is diesel. Next come heating oils, lubricating oils, and paraffin wax. Technically, diesel has a heavier molecular weight than gasoline, giving it a much thicker consistency compared to the water-like consistency of gasoline.
Best Diesel Additives FAQ:
Q: What are diesel fuel additives?
A: These are chemical formulations that are added to diesel fuel with the goal of improving the lubricant characteristics of diesel fuel especially on the distributor and rotary types of injection pumps. Additives can help improve the lubricity of your diesel fuel while also addressing deposits, cetane reduction, and cold flow issues as well as a host of other benefits.
Q: What is cetane and why boost it?
A: Diesel guys never mention anything about octane. Instead, they always look at the ‘cetane’ rating of their diesel fuel. Cetane rating is a measure of the diesel fuel’s tendency to burn or ignite. Cetane is a colorless gas that requires very minimal heat to ignite. And since diesel engines compress air making it super-hot before injecting the needed fuel, improving the cetane in the fuel can also improve engine performance. So why boost cetane ratings? It is basically to improve the overall performance of your diesel engine.
Q: Does it void my new vehicle’s warranty?
A: The Magnusson-Moss Act of 1975 specifically prohibits the voiding of a warranty by any equipment manufacturer simply because a consumer used a fuel additive. So, putting a diesel fuel additive of your choice into your new vehicle will not void its warranty. This is because even original engine manufacturers produce their own brand of fuel additives that can be a lot similar to third-party products. Additionally, producers of diesel fuel often put additives into their products to make them stand out from competition and to adhere to regulations.
Q: How should I add the product to my fuel?
A: Manufacturers of fuel additives have their different methods of using their fuel additives so it is wise to check the instructions before emptying a bottle into your tank. Generally, it is best to have the fuel tank nearly empty so you can pour the correct amount of fuel additive into your car’s fuel tank before filling it with diesel fuel.
