2023 Infiniti Q50 Engine Oil and Fluids Guidelines

Managing the engine oil and fluids in the 2023 Infiniti Q50 is an important part of keeping the car in good shape and making it run at its best. This high-end automobile is known for its precise engineering and smooth driving experience. It relies on a carefully thought-out system to keep the engine running at its best while keeping it lubricated and cool. The carefully chosen engine oil’s thickness and quality not only lowers friction and wear in the engine, but it also helps get rid of heat, which improves performance and extends the life of the engine. In addition to engine oil, the Q50 manages other important fluids like gearbox fluid, coolant, brake fluid, and power steering fluid. All of these play key roles in making sure the car runs smoothly, reliably, and safely. Following maintenance schedules, checking the car regularly, and changing fluids are important for keeping it in good shape and letting drivers enjoy the Infiniti Q50’s unique mix of luxury, power, and precision on the road. This shows the brand’s dedication to engineering excellence and driver satisfaction.

ENGINE OIL

CHECKING ENGINE OIL LEVEL

1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15 minutes for the oil to drain back into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range . If the oil level is below , remove the oil filler cap and pour recommended oil through the opening. Do not overfill .
6. Recheck oil level with the dipstick.

It is normal to add some oil between oil maintenance intervals or during the break-in period, depending on the severity of operating conditions.

CAUTION
Oil level should be checked regularly. Operating the engine with an insufficient amount of oil can damage the engine, and such damage is not covered by warranty.

CHANGING ENGINE OIL AND FILTER

Vehicle set-up

   • Then remove the other bolts that hold the undercover in place.

CAUTION
Make sure the correct lifting and sup-port points are used to avoid vehicle damage.

Engine oil and filter

1. Place a large drain pan under the drain plug.
2. Remove the oil filler cap.
3. Remove the drain plug with a wrench and completely drain the oil.
   CAUTION
   Be careful not to burn yourself, as the engine oil is hot.
   • Waste oil must be disposed of properly.
   • Check your local regulations.
4. (Perform steps 4 to 7 only when the engine oil filter change is needed.) Loosen the oil filter with an oil filter wrench. Remove the oil filter by turning it by hand.
5. Wipe the engine oil filter mounting sur-face with a clean rag.
