Synplus SN GF-5 5W/20 represents the pinnacle of full synthetic engine lubricants, offering top-notch engine protection and fuel efficiency for both new and older petrol engines. This exceptional oil not only meets but surpasses the latest API SN Plus specification and boasts ILSAC GF-5 fuel efficiency performance. It’s also compatible with older API petrol specifications, making it versatile for various applications.

Designed with a focus on meeting Ford specifications WSS-M2C945-A and Chrysler MS-6395, Synplus SN GF-5 5W/20 is particularly well-suited for vehicles requiring these standards, and it’s also recommended for many later model Subaru vehicles.

This oil is meticulously crafted using full synthetic base oils and specially selected additives, resulting in a low SAPS (Sulfated Ash, Phosphorous, and Sulfur) high-performance engine oil. It incorporates the latest advancements in oil formulation and additive technology to provide superior engine protection.

Synplus SN GF-5 5W/20 is ideal for petrol four-stroke engines, especially small turbocharged engines operating under various conditions, including moderate, severe, or fluctuating situations such as cold starts, stop-and-go driving, and high-temperature highway cruising.

In recent years, automakers have introduced smaller, more powerful engines to meet stringent fuel economy standards. While these smaller engines reduce vehicle weight and enhance fuel efficiency, they also demand higher-quality lubricants due to:

• Increased Heat Output: Smaller engines generate higher temperatures, leading to accelerated acid formation, nitration, and the buildup of deposits and sludge. These conditions degrade the oil and cause a rapid increase in oil viscosity, which can harm fuel efficiency.

• Increased Engine Pressures and Speed: These engines operate at elevated pressures and speeds, making it more challenging for the oil to maintain a lubricating film that prevents metal-on-metal contact. This contact accelerates wear on components like the valve train.

• Low-Speed Pre-Ignition (LSPI): Some turbocharged small-capacity engines are prone to LSPI, a phenomenon that this oil helps combat.

In essence, Synplus SN GF-5 5W/20 is engineered to tackle these modern engine challenges head-on, ensuring top-tier engine protection, fuel efficiency, and longevity.


• Full Synthetic Base Oils: Crafted from top-tier synthetic base oils, this oil offers extended lubricant lifespan and exceptional cold start protection.

• Low-Speed Pre-Ignition (LSPI): Compliant with the API SN Plus performance level, this oil is specially formulated to combat LSPI and mitigate timing chain wear in small turbocharged petrol engines.

• Oxidation/Corrosion Resistance: Synplus SN GF-5 5W/20 goes above and beyond by exceeding API SN Plus oxidation requirements in the TEOST MHT Deposit Formation test. It also surpasses corrosion requirements in the Sequence VIII Bearing Weight Loss test and the Sequence VG Engine Sludge and Oil Screen Clogging test.

• Excellent Cam Wear Protection: This oil provides outstanding protection against cam wear, exceeding the API SN Plus Sequence IVA Average Cam Wear Limit by a substantial margin. This promotes longer engine life, with cam wear results consistently below 20μm compared to the API SN limit of a maximum 90μm cam wear.

• Excellent Emission Control: Synplus SN GF-5 5W/20 not only meets but surpasses modern emissions standards, contributing to extended durability of emissions systems.

  • Catalytic Converter Protection: One of the standard tests for the API SN Plus Resource Conserving performance level is the measurement of the % of Phosphorus retained in the engine oil using the Sequence IIIGB test. Phosphorus leaching out of the engine oil, poisoning and clogging the catalytic converter in the vehicle exhaust system, can be a major issue. API SN Plus measures and puts limits on this leaching, thus controlling catalyst poisoning and exhaust system degradation.
  • Fuel Efficiency: Synplus SN GF-5 5W/20 meets the ILSAC GF-5 as well as the API SN Plus Resource Conserving performance requirements, having the technology for better handling of internal friction, thus translating into better fuel economy and reduced maintenance costs. Performance in the Sequence VID test for Improved Fuel Efficiency of greater than 2.6% and Sequence IIIG Oil Thickening and Cam Lifter Wear support these claims.
