Lexus LC 500 V8 Direct Injection Carbon Buildup Malaysia
The 2UR-GSE V8 uses direct injection — intake valve carbon accumulates from 80,000–100,000 km. Walnut blasting for a V8 is a complex, expensive job. The LC 500h's V35A-FTS uses bi-injection (port + direct) — less severe carbon. Schedule carbon cleaning at 100,000 km for LC 500.
LC 500 D-4S Carbon Buildup
The LC 500 2UR-GSE uses D-4S dual injection — port injection reduces carbon risk compared to pure DI. On a flagship V8 driven conservatively on Malaysian roads, carbon buildup is slow. Walnut blasting at 80,000 km is recommended as a precaution. The LC 500h V6 hybrid has even lower carbon risk. After any intake cleaning, follow up with fresh 0W-20 oil to flush debris.
