Fuel Efficiency
From Wikipedia: [https://en.wikipedia.org/wiki/Fuel_efficiency]
Fuel efficiency is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel (i.e. petrol or diesel) into kinetic energy or work (i.e. the propulsion or driving of your vehicle forward).
What that means
Your fuel efficiency is a measure of how efficient your engine is in terms of how much fuel it consumes to drive a certain distance. For example, you would say that a car travels 60 miles per gallon of petrol (60mpg) is much more efficient than one that only travels 30 – 40 miles per gallon.

Where Fuel Additives can help
Fuel additives and oil products are very under rated in keeping your engine running well. Generally they work by either improving the efficiency of your fuel in a way that can improve your mpg - or by ensuring that the deposits caused by your engines’ combustion process are cleared / cleaned from the engine. Top shelf fuel additives will do both.

Diesel additives also have major benefits in maintaining a clean diesel engine, and will help to prevent problems that can occur with your DPF (Diesel Particulate Filters) such as clogging or your engine running in reduced power mode.
Coby Autos use the BG Products range of Fuel Additives. We’ve listed the main benefits of different types of additives below, but for more information see their website.
Key Uses of Fuel Additives
Fuel additives, when used properly can:
- Improve Fuel Economy / MPG
- Restore Lost Performance
- Reduces Emissions
- Prevent Problems
Compression restoration & Engine flush
- Remove more of the old oil
- Restore vitally important compression
- Restores Power & Economy
- Prolongs life of emissions control devices (such as DPF etc)
Oil / Engine Protection
Soot formation in the oil can lead to accelerated wear of vital engine components
- Increases Friction Resistance
- Controls Soot formation
- Raises Acid Resistance
- Protects your engine for longer and better than standard oil
Fuel additives when used correctly will typically increases MPG from between 4% – 6%.
