The 1993 Lexus SC400 uses R-12 refrigerant for its air conditioning system. However, R-12 is no longer produced and is considered a controlled substance due to its environmental impact. Many owners choose to retrofit their systems to use R-134a, which is more environmentally friendly. If considering a retrofit, it's important to ensure that the system is properly converted to avoid damage.
