Engine wear and tear
All engines are designed and built to run on petrol with a specific octane, or cetane in the case of diesel. The problem is that over time, as a car ages, its thirst for octane increases. This is caused by the accumulation of deposits inside the engine, although, the main problem from carbon deposits, gums, varnishes, and dirt also play a part. When your engine´s "appetite" for octane increases, it will eventually lead to obvious signs of octane starvation such as poor drivability, lack of engine response and/or power, excessive exhaust emissions, knocking and pinging.
Previously, the only options were to run your car on expensive higher octane fuel, to get your vehicle de-carbonized with additives which dissolve carbon residues or, perhaps, add one of the many doubtful octane boosters. However, none of these options are satisfactory as some have questionable long term effects, and all work out to be expensive in the short and long term.
But on the market now, there is an answer to this problem:
Boogie Energy Pill!
Origin of Boogie Energy Pill
Fuel conditioners pills were first produced over 20 years ago. At that time people were looking for ways to improve:

The unique combination of three effective components makes all driver´s wishes come true!
An oil substance and emulgator create a slipery film in roadrollers, which reduces surface tension.
The Ferrocene substance was found to adjust the molecular structure of fuel, ensuring the mixture burns completely.
Boogie Pill causes better fuel burning of molecules of light, medium and heavy elements, thereby improving fuel economy.
What is so special about the Boogie pill?
Boogie Pill is a fuel conditioner which is hydrocarbon compatible. It burns completely – no residue is left. Most other fuel treatments are additives, which are not chemically compatible, and over a long period of time leave unburnt residues in the engine. The Boogie pill with its high tech formulation performs many tasks on its own. Cost of engine treatment by Boogie Energy Pill is more affordable than having to buy four or more products.
Boogie Energy Pill dissolves quickly in petrol, diesel or ethanol fuel, which implies an improvement in the combustion process. Improved combustion create a cleaner burn in the engine, reduces emissions of exhaust gases and enhances air quality in places with heavy traffic.
