Synthetic, compatible with exhaust gas after-treatment systems, motor oil for gasoline and diesel engines of passenger cars. Produced using a low-ash additive package in accordance with the requirements for Euro IV engines. Specially developed for high-performance diesel and gasoline engines of passenger cars equipped with catalytic converters (TWC) or particulate filters (PDF), and requiring the use of low-ash oils with HTHS viscosity values of more than 3.5 mPa.s. It has exceptional anti-wear and cleaning properties, reduces the formation of carbon deposits on pistons and sediment deposits in the engine and turbocharger. The performance characteristics of Gulf Formula RNX 5W-30 exceed the requirements for oils for the latest Renault models and other automakers, which recommend the use of ACEA C4 oils. FEATURES AND BENEFITS Active detergent components reduce the formation of carbon deposits on pistons, prevent the formation of sludge deposits in the engine and thickening of the oil with soot, helping to extend engine life. Low SAPS additive package helps extend the life of diesel particulate filters and minimizes the damaging effects of exhaust gases on the catalytic converter. The latest additive technologies provide long-term, reliable protection of engine components against wear, oxidation and corrosion. Good low-temperature fluidity makes it easier to start the engine in winter and provides improved protection of its parts from wear during cold starts. APPLICATION Recommended for the latest models of Renault passenger cars, in particular for Euro IV diesel engines with particulate filters, which require the use of an oil to Renault RN 0720 specification. Suitable for the latest diesel and petrol engines of cars, vans and light trucks equipped with catalytic converters or particulate filters that require the use of ACEA C4 class motor oils. Note: This oil is not suitable for use in some engines that require a high viscosity oil or those that operate on low quality, high sulfur fuels. STANDARDS AND APPROVALS Complies with: ACEA C4; MB 226.51. Officially approved: Renault RN 0720.
