acura rlx oil capacity

If the engine oil life is less than 15%, you will see the Maintenance Minder messages appear on the multi-information display every time you set the power mode to ON. The messages notify you when to change the engine oil, or when to bring your vehicle to a dealer for indicated maintenance services.

We recommend that you check the engine oil level every time you refuel. Park the vehicle on level ground. Turn off the power system. You can check the oil level without the engine having run beforehand. If the engine has been running, wait approximately three minutes before you check the oil.

Oil is a major contributor to your engine’s performance and longevity. If you drive the vehicle with insufficient or deteriorated oil, the engine may fail or be damaged.

This seal indicates the oil is energy conserving and that it meets the American Petroleum Institute’s latest requirements. Use a Genuine Acura Motor Oil or another commercial engine oil of suitable viscosity for the ambient temperature as shown here.

Synthetic oil

You may also use synthetic motor oil if it is labeled with the API Certification Seal and is the specified viscosity grade.

Engine Oil Additives

Your vehicle does not require oil additives. In fact, they may adversely affect engine performance and durability.

You can optimize your fuel economy with proper maintenance of your vehicle. Always maintain your vehicle in accordance with the messages displayed on the multi-information display.

  • Use the recommended viscosity engine oil, displaying the API Certification Seal.
  • Maintain the specified tire pressure.
  • Do not load the vehicle with excess cargo.
  • Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside adds weight and increases wind resistance.

You must change the engine oil and oil filter regularly in order to maintain the engine’s lubrication. The engine may be damaged if they are not changed regularly

You will need a special wrench to replace the oil filter. You can buy this wrench from a dealer. When installing the new oil filter, follow the instructions supplied with the oil filter.

Reinstall the engine oil fill cap. Start the engine. The low oil pressure indicator should go off within five seconds. If it does not, turn off the engine, and check your work.

Put a new washer on the drain bolt, then reinstall the drain bolt.

Tightening torque:

  • 30 lbf∙ft (40 N∙m, 4.0 kgf∙m)

Do not fill the engine oil above the upper mark. Overfilling the engine oil can result in leaks and engine damage. If any oil spills, wipe it away immediately. Spilled oil may damage the engine compartment components.
