Detailed Product Description
Honda Genuine Ultimate Full Synthetic Motor Oils are premium quality, full-synthetic engine oils designed to provide maximum engine protection for Honda and Acura vehicles under all operating conditions. They surpass Honda and Acura requirements to further minimize harmful engine deposits and maximize fuel economy. Honda motor oils are tested and approved by Honda R&D.
Honda Genuine Ultimate Full Synthetic Motor Oil is formulated with synthetic base stocks that provide enhanced performance benefits compared with conventional engine oils. These benefits include improved protection against viscosity breakdown and deposit formation at high temperatures; lower volatility for reduced oil consumption; and faster oil circulation at low temperatures for easier starting and better protection during cold starts.
Honda Genuine Ultimate Full Synthetic Motor Oil exceeds API SN and ILSAC GF-5 performance requirements for gasoline engines. It is "Resource Conserving" for improved fuel economy and protection of emissions system catalysts. The SAE 5W-30 viscosity grade also meets Honda HTO-06 requirements for protection of turbocharged engines such as on the RDX.
