API SG/SH or higher, SAE 10W-30 or 10W-40 recommended (check manual for precise grades and requirements, including potential for specific rotary oil additives).
Coolant Type:
Ethylene glycol-based antifreeze (typically a 50/50 mix with distilled water)
Brake Fluid Type:
DOT 3 or DOT 4
Gear Oil Type:
API GL-4 or GL-5 hypoid gear oil (SAE 80W-90 recommended for manual transmission and differential)
Known Issues:
