Gasoline is a fuel for engine widely used for automobiles and

motorcycles. The numbers 91 and 95 stated the Octane, which

is the rate of resistance to ignition of Gasoline. It also implies

that the higher the Octane, the higher its resistibility to engine

knockdown. The most important part is to choose the right

Gasoline for the right engine. In that way, it will help support

the engine and enhance its performance. On the other words it

will also help us to keep some maintenance money in the

pocket.

IRPC offers various grades of Gasoline :

ULG91Granted Euro 4 standard, IRPC ULG 91 is one of the best

Gasolines for automobiles that is not only help cleansing your

engine and enhance its performance during the usage, but also

help reduce pollution and be environmental friendly.
