Service Intervals:
Refer to manual for specific intervals. General recommendations include oil and filter changes every 5,000-7,500 miles or annually, coolant checks, brake fluid checks, and comprehensive inspections at major mileage points (e.g., 15,000, 30,000 miles).
Engine Oil Type:
High-quality synthetic engine oil, viscosity typically 10W-60 or 10W-50. (Exact spec in manual)
Coolant Type:
Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. (Exact spec in manual)
Brake Fluid Type:
DOT 3 or DOT 4 high-temperature brake fluid. (Exact spec in manual)
Transmission Fluid Type:
Specific manual transmission fluid (e.g., GL-5 rated gear oil). (Exact spec in manual)
Differental Fluid Type:
Specific limited-slip differential (LSD) fluid or gear oil. (Exact spec in manual)
Known Issues:
Can include electrical system gremlins, HVAC system performance issues, aging rubber components, potential clutch wear due to performance driving, and general maintenance complexity due to exotic nature. Proper maintenance is crucial for reliability.
Common Wear Items:
Clutch assembly, suspension bushings, brake pads and rotors, ignition coils, and fuel injectors are common wear items on high-performance vehicles of this age.
Brand Heritage:
Lamborghini has a storied history of producing exotic, high-performance sports cars, starting with the iconic Miura and Countach, establishing a reputation for dramatic styling and powerful V12 engines.
Model Evolution:
The Diablo succeeded the Countach. The 1993-1994 models represent an evolution of the original Diablo, with minor styling updates and performance improvements. The 2WD version was introduced to make the car more accessible and manageable for some drivers compared to the all-wheel-drive variants.
