Fuel Additives - The Basics

  • I feel like my engine isn't running very well...
  • Why not try using
    fuel additives?
  • I put those in my fuel tank!
    But honestly, I don't really understand them.
    How are they different from water-absorbing agents?
  • Well, let me explain
    the basics.

Fuel Additives - The Basics

"Fuel additives go by a lot of different names—engine cleaner, injector cleaner, deposit cleaner, fuel system cleaner, engine system cleaner, etc. They are injected into a gasoline or diesel fuel tank, and while the car is running they remove injector deposits and restore the original performance of the engine. Fuel additives for gasoline are a particularly easy way to do engine maintenance, since they also clean the intake valve and the combustion chamber."

Deposits can easily build up in older cars, cars that repeatedly stop and go, and cars used for short-distance driving, so we recommend periodic use of fuel additives.
Looking overseas, there are some countries where fuel quality is poor, so deposits can easily adhere to the engine interior.

Main types of fuel additives

  • 1. For automobiles with gasoline engines
  • 2. For automobiles with diesel engines
  • 3. For two-wheeled vehicles using gasoline
  • 4. For farm machines
  • 5. For boat engines
Now let's move on to an explanation of fuel additives for automobiles with gasoline engines.

Effects of fuel additives

When you use an engine cleaner, you can expect the following effects.

  1. Restoration of drivability (acceleration, accelerator response)
  2. Elimination of rough idling
  3. Prevention of defects before they occur (preventive maintenance)
  4. Recovery of fuel efficiency and emissions
  5. Restoration of DPF regeneration frequency (diesel)

*Effects will vary depending on usage, engine condition, etc.

Engine interior cleaning mechanism

  1. The effective component penetrates the deposits.
  2. The deposits are gradually peeled away.
  3. Removed deposits flow to the combustion chamber with the fuel.
  4. Deposits are completely combusted along with the fuel.
  5. With one use in a full fuel tank, the engine interior is clean.

*Two consecutive uses are recommended for vehicles that are heavily driven.

  • *The above illustrations, as well as illustrations within the movie that display the effects of the engine cleaner, are strictly for illustrative purposes.

Since they are used for critical parts in the engine—the "heart" of the automobile—we recommend using high-reliability fuel additives.
