So, as we embark on this DIY adventure, let’s keep it friendly, and experimental, and always remember that our homemade recipes are here to complement, not replace, the tried-and-true commercial options.

Happy experimenting, and let’s keep those engines smiling! Here are the ingredients you need to get started…

Ingredients You Need

  1. Bio-Based Additives: a. Vegetable Oil: Often derived from crops like soybeans or canola, vegetable oil serves as a renewable and bio-based source of lubricity and energy content. b. Ethanol: A bio-based alcohol commonly derived from corn or sugarcane, ethanol can enhance combustion efficiency and act as a solvent for cleaning.
  2. Cleaning Agents: a. White Vinegar: This mild acid is effective in breaking down deposits and contaminants in the fuel system, promoting cleaner combustion. b. Baking Soda: As a mild abrasive, baking soda can aid in removing carbon deposits and impurities from various engine components.
  3. Lubricity Enhancers: a. Isopropyl Alcohol: Besides its cleaning properties, isopropyl alcohol enhances lubricity in the fuel system, reducing friction between moving parts. b. Vegetable Oil (mentioned above): Vegetable oil not only serves as a bio-based additive but also contributes to lubricity.

B. Importance of Using Readily Available and Eco-Friendly Components

  1. Cost-Effectiveness: Utilizing readily available ingredients makes homemade diesel additives cost-effective, as these components are typically more affordable and can be easily obtained from local stores.
  2. Sustainability: Choosing bio-based additives promotes sustainability by reducing reliance on fossil fuel-derived products. This aligns with eco-friendly practices and contributes to a smaller carbon footprint.
  3. Accessibility: Readily available components ensure accessibility for a broader audience, allowing more individuals to experiment with and benefit from homemade diesel additives without the need for specialized or hard-to-find ingredients.
  4. Environmental Impact: Eco-friendly components not only contribute to sustainability but also minimize the environmental impact of fuel additives. Homemade additives made from bio-based and non-toxic materials are less likely to harm the environment during production, use, and disposal.
  5. DIY Spirit: The use of easily accessible ingredients encourages a do-it-yourself (DIY) approach, empowering individuals to take charge of their fuel system maintenance. This promotes a sense of self-reliance and resourcefulness.

By emphasizing readily available and eco-friendly ingredients in homemade diesel additives, individuals can contribute to both their own cost savings and a more sustainable, environmentally friendly approach to fuel system maintenance.

But Before You Pour Your DIY Fluid, Make Sure The Tank is Clean

I use methylated spirits when cleaning the tank. Using methylated spirits can indeed be an effective way to combat bacteria and fungi that might be hanging out in there. The spirits act as a strong solvent, helping to dissolve and clean any residues that could potentially mess with your engine’s performance.

Here’s a friendly step-by-step guide for using methylated spirits in your fuel tank:

  1. Prepare Your Vehicle:
    • Make sure your car is parked in a well-ventilated area, preferably outdoors.
    • Ensure the engine is off and the vehicle is cool before you start.
  2. Check for Compatibility:
    • Confirm that using methylated spirits is compatible with your vehicle. Consult your car’s manual or seek advice from your manufacturer.
  3. Empty the Tank:
    • If possible, run the fuel level as low as you can without risking your engine stalling.
    • Consider draining any remaining fuel from the tank.
  4. Methylated Spirits Mix:
    • Mix a small amount of methylated spirits with a larger amount of fuel. A common ratio is around 1 part methylated spirits to 5 or 10 parts fuel.
  5. Pour the Mix into the Tank:
    • Gently pour the methylated spirits-fuel mix into the fuel tank.
  6. Swirl and Soak:
    • Swirl the vehicle gently to allow the mix to reach all parts of the tank.
    • Let the mix soak for a while, ensuring it has a chance to break down any deposits.
  7. Drain and Refill:
    • Drain the tank thoroughly.
    • Refill with fresh, clean diesel fuel.
  8. Run the Engine:
    • Start the engine and let it run for a few minutes to circulate the clean fuel through the system.

Remember, safety first! Always follow safety guidelines when working with flammable substances and ensure proper ventilation during the process. If you have any doubts or concerns, it’s a good idea to consult with a professional or your vehicle manufacturer.


Alright, fuel aficionados, we’ve had a blast exploring the DIY wonderland of homemade diesel additives! As we wrap up our adventure, let’s remember – our homemade concoctions are like the cool sidekicks to the superhero commercial additives. They bring a bit of fun, a touch of kitchen creativity, but they’re not here to steal the spotlight.

So, as you rev up your engines with your newfound DIY knowledge, give a nod to the pros too. Commercial additives are the seasoned champions, rigorously tested and ready for anything. Our homemade mixes? Well, they’re more like the friendly neighbors waving from the driveway.

Keep experimenting, keep that engine purring, and always remember it’s a friendly collaboration between DIY magic and commercial wizardry. Happy driving, and may your fuel efficiency be as high as your spirits!
