2. WHAT IS RON?
RON stands for Research Octane Number
A rating used to measure a fuels knocking resistance in
spark-ignition internal combustion engines.
Knocking is what happens when parts or all of the air-
fuel mixture prematurely ignites before the flame from
the spark plug can reach it.
This can be caused by ignition timing that is too early or
engine overheating.
3. Basically RON is the grade of petrol capabilities against
abnormal combustion and generate energy at the
proper time during the burning process.
Highest grade Ron does not guarantee a good efficiency
of the vehicle
4. WHAT IS EURO4M ?
Euro 4M standard for RON97 petrol. Euro 4M is adapted
from the European Union’s (EU) strict rules on fuel
standards and specifications to manage fuel quality that
have impact on the environment.
The main objective of the fuel standard upgrade is to
improve emissions for better air quality. This also has to
be done in unison with the availability of Euro 4
compliant vehicles.
5. WHY IS THERE A CHANGE FROM
EURO 2M TO EURO 4M?
The Euro 4M implementation mandated by the
Malaysian government is to reduce exhaust emissions
Lower levels of harmful exhaust emissions from motor
vehicles and thus, cleaner and better air quality
The main difference between euro 2M and euro 4M
standard fuel is the sulphur content which was
significantly reduced from 500ppm to 50ppm.
6. DIFFERENCE BETWEEN
RON95 & RON97
RON95
95% containing octane
and the remaining is
pentane
Less efficient
combustion
Fast combustion
Price cheaper
Low viscosity
Suitable for carburator
Plumbum
RON97
97% containing octane
and the remaining is
pentane
More efficient
combustion
Slow combustion
Expensive price
High viscosity
Suitable for injection
engine
No plumbum

8. OCTANE PROPERTIES
Octane is the ability to withstand the pressure in the
combustion chamber.
The higher octane content, it's difficult to burn octane
in your vehicle engine
10. Ron97 is the best choosen to environment
because:
Complete combustion for engine
High efficiency, lower petrol consumption
which is better for environment
Lower exhaust emission (low carbon
dioxide/ monoxide)
Does not contain plumbum which lower
probability of carbon created
11. Sulphur in fuel results in vehicles emitting
harmful pollutants during the combustion
process.
Presence hinders exhaust after-treatment
technologies from operating as they
should,
Causing further harm to our health and
environment.
