What kind of oil does a 2015 Lexus IS350 take?
The 2015 Lexus IS350 typically uses 0W-20 synthetic motor oil. This article outlines the official spec, why that viscosity is recommended, and practical maintenance tips for keeping the engine in top condition.
Recommended oil type and specifications
Understanding the right oil starts with viscosity, synthetic composition, and the standards the oil must meet for a 3.5-liter V6 (2GR-FSE) engine.
- Viscosity: 0W-20 synthetic motor oil
- Type: Full synthetic recommended
- Specifications: API SN (or newer) and ILSAC GF-5 (or newer) compliance
- Capacity: Approximately 6.4 quarts (6.0 liters) with filter
- Change interval guidelines: Follow the owner’s manual; with synthetic oil, many Lexus models specify around 10,000 miles or 12 months, whichever comes first, though severe service may require more frequent changes
These specifications align with Toyota/Lexus guidelines for the 2015 IS350 and similar 2GR-FSE engines. Regional variations can occur, so it’s wise to verify against your exact vehicle manual or a Lexus dealer.
Notes on climate and driving conditions
In addition to the base spec, climate and driving habits can influence oil choice and maintenance cadence.
- Cold climates: 0W-20 remains appropriate because of its excellent cold-start performance
- Hot or performance-driven driving: Use a high-quality 0W-20 synthetic that meets spec; monitor oil level more frequently
- Regular checks: Check oil level monthly and before long trips; top up with the same grade if needed
Always rely on the owner’s manual for exact intervals and capacity. Severe service or regional requirements may adjust the recommended schedule.
Oil capacity and practical maintenance reminders
Knowing the capacity helps with oil changes and topping up, as well as avoiding overfilling during servicing.
- Oil capacity (with filter): about 6.4 quarts (6.1 liters)
- Best practice: Use a quality oil filter and dispose of used oil according to local regulations
For VIN-specific figures or any deviations by market, consult the owner’s manual or a Lexus-certified technician.
