Target Audience:
Professional technicians and advanced DIY enthusiasts.
Oil Change Interval:
Typically 3,000-5,000 miles or 3-6 months, depending on driving conditions and oil type. Consult manual for specific recommendations.
Transmission Fluid Change:
Every 30,000-50,000 miles for automatic transmissions. Check manual for specific intervals and conditions.
Coolant Change:
Every 30,000-50,000 miles or 2-4 years, depending on coolant type (Dex-Cool for later models).
Engine Oil Type:
SAE 5W-30 recommended for most conditions. API certified oil.
Coolant Type:
