Honda is replacing the Ultimate Full Synthetic oil (GF-6) with a new and improved HRC Formula R (GF-7A). HRC Formula R Full Synthetic oil was developed as a premium product in close collaboration with Phillips 66—Honda and Acura’s trusted partner for over 15 years and proud sponsor as well as the official lubricant provider of the race winning Acura ARX-06 race cars. Engineered under extreme conditions, HRC Formula R oils deliver unmatched thermal stability, wear protection and turbocharged engine performance. Every bottle carries the DNA of motorsport innovation. Backward compatible with all Honda models that require 0W-20, HRC Formula R oils meet or exceed API SP and GF-7A standards—ensuring peace of mind with every mile.
