Mazda CX-60 Carbon Cleaning Malaysia — 2.5T
CX-60 2.5T: direct injection — carbon on intake valves at 60,000–80,000 km. Turbo: higher intake temperatures accelerate carbon vs naturally aspirated. Walnut blast: RM 1,100–1,800. Symptoms: rough cold idle, hesitation under boost. City driving: faster carbon buildup than highway.
