Engine Oil:
Likely 10W-30 or 10W-40 for gasoline engines, with specific API service classifications provided in the manual. Diesel engines would have different specifications.
Transmission Fluid:
ATF+3 or ATF+4 for automatic transmissions (specific designation varies by year), and manual transmission fluid (e.g., gear oil) for manual gearboxes. Refer to manual for exact part numbers and specifications.
