Oil type and maintenance recommendations
Using the right oil and following the schedule helps protect the engine and maintain warranty coverage. The 3.5L V6 in the RX 350L is designed for modern synthetic oil under Lexus guidelines.
- Viscosity: usually 0W-20 full-synthetic oil is recommended for this engine.
- Oil specification: a grade that meets API/ILSAC 0W-20 standards and Lexus/OEM approval is preferred.
- Oil change interval: follow the owner's manual; synthetic oils typically allow longer intervals than conventional oil, but conditions and mileage affect timing.
- Oil filter: install a new OEM or equivalent filter with every oil change to ensure proper filtration.
Regular checks are important. After adding oil, recheck with the dipstick and avoid overfilling, which can lead to engine problems.
Do-it-yourself oil change steps
For readers who plan a DIY job, here are general steps commonly followed by enthusiasts. Always consult the official service manual for specifics to your VIN and locale.
- Prepare the correct oil grade and a new filter (0W-20 synthetic) and a drain pan.
- Warm the engine, then park on level ground and set the parking brake.
- Place a drain pan under the oil drain plug, remove the plug, and let the old oil drain completely.
- Remove and replace the oil filter, lubricating the new gasket with a small amount of new oil.
- Reinstall the drain plug securely; pour in the recommended 6.4 quarts gradually.
- Start the engine, run it for a minute, then shut off and check for leaks; after cooling, check the dipstick to ensure the level is at the full mark.
Note: If you’re unsure about any step or VIN-specific requirements, have a certified technician perform the service.
