What oil does a 2018 Lexus RX take?
The 2018 Lexus RX uses 0W-20 synthetic engine oil for both the RX 350 and the RX 450h (hybrid) models.
For 2018 RX versions, Lexus specifies a low-viscosity, full-synthetic oil that meets API SN (or newer) standards and ILSAC GF-5 (or newer). The same oil grade applies to the gas-powered RX 350 and the hybrid RX 450h, with differences limited to capacity and maintenance intervals rather than the oil type itself. Always verify the exact specification in the owner’s manual or with a Lexus dealer, especially if you live in extreme climates or have unique driving conditions.
Oil specifications for the 2018 Lexus RX
Below is a quick reference to the recommended oil type by the primary 2018 RX variants. Both variants share the same recommended viscosity and standard, with any model-specific notes focused on capacity and service timing rather than a different oil grade.
- 2018 RX 350 (3.5L V6): 0W-20 synthetic oil; API SN or newer; ILSAC GF-5 or newer.
- 2018 RX 450h (hybrid): 0W-20 synthetic oil; API SN or newer; ILSAC GF-5 or newer.
In both cases, use a high-quality full-synthetic oil that meets the above standards. Always confirm the exact specification and any regional notes in your owner’s manual or with a Lexus service advisor.
Why 0W-20 and practical tips
0W-20 is chosen for its balance of cold-start performance, fuel efficiency, and protection for modern engines. If you cannot source 0W-20, consult Lexus guidance before substituting with a different viscosity, and avoid extending oil-change intervals beyond what the manual recommends.
Additional notes on service
Oil capacity and exact service intervals can vary slightly between the RX 350 and RX 450h depending on production year and regional guidelines. Always follow the maintenance schedule in your owner’s manual and use the oil grade specified above. If in doubt, ask a Lexus technician or your dealership for the precise specification for your vehicle’s VIN.
Summary
In brief, the 2018 Lexus RX requires 0W-20 synthetic engine oil for both the RX 350 and the RX 450h. Use full synthetic that meets API SN or newer and ILSAC GF-5 or newer, and always refer to the owner’s manual for exact capacity and maintenance intervals. This ensures optimal protection, performance, and efficiency for your vehicle.
