The 2018 Volkswagen Tiguan is recommended to use RON 95 unleaded gasoline in Malaysia. This is the most common type of fuel locally and can fully meet the requirements of the vehicle's 1.4-liter TSI or 2.0-liter TSI turbocharged engines. Meanwhile, it complies with the fuel standards set by the Malaysian government. Although some high-performance models may require RON 97 for better power performance, the Tiguan can perform normally with RON 95 as per the factory settings, and it's more cost - effective. Malaysian car owners should note that the main difference between gasoline with different RON values lies in their anti - knock capabilities. RON 95 can effectively prevent engine knocking, while RON 97 is more suitable for engines with a higher compression ratio. It is recommended to have regular maintenance at authorized service stations and use the fuel additives recommended by the manufacturer to keep the fuel system clean. This can extend the engine's lifespan and maintain fuel efficiency. Additionally, due to the hot and humid climate in Malaysia, try to avoid running the fuel tank completely empty before refueling to prevent condensed water from mixing into the fuel system.
