S-OIL makes various efforts to clear up consumers' suspicions related to product prices and maximize consumer benefits by applying a reasonable and competitive pricing policy. Implementing an independent product pricing system that takes on board various factors that affect domestic fuel prices such as fluctuations in international oil prices, F/X rates and domestic market trend, S-OIL is leading the domestic pricing with fair and reasonable policy.
