What kind of oil does a 2015 Lexus RC 350 F Sport take?
The 2015 Lexus RC 350 F Sport uses synthetic 0W-20 motor oil, with a typical fill of about six quarts (approximately 5.7 liters) including the filter. Always verify the exact specification on your vehicle’s oil filler cap or in the owner’s manual.
The RC 350 F Sport, powered by a 3.5-liter V6, relies on precise oil specifications to maintain performance and reliability. Here is what owners and technicians need to know about the official guidance and practical considerations for this model year.
Official specification
Lexus specifies a high-quality synthetic motor oil with a viscosity of 0W-20 for the 2015 RC 350 F Sport. The oil should meet API Service SN (or newer) and ILSAC GF-5 (or newer) standards. Using 0W-20 helps with cold-start performance, engine wear protection, and fuel efficiency.
Viscosity and standards
Viscosity: 0W-20. Standards: API SN (or newer) and ILSAC GF-5 (or newer). For the 2015 model year, these specifications were standard, and many shops now accept newer GF standards as compatible. Always use oil that meets or exceeds the listed specs and verify on the filler cap or in the manual.
Oil capacity and service interval
Oil capacity is roughly 6 quarts (about 5.7 liters) with the oil filter installed. For normal driving, Lexus generally recommends changing synthetic oil every 10,000 miles or 12 months, whichever comes first; more frequent changes may be advised under severe driving conditions. The vehicle’s oil life monitor will indicate when a service is needed.
Practical guidance for owners
To stay within the official guidance, choose a synthetic 0W-20 that meets API SN or newer and ILSAC GF-5 or newer. Use a quality oil filter and either OEM or equivalent parts. Do not substitute with viscosities outside the approved range without consulting a dealer or the owner’s manual. If you’re in a region where 0W-20 is hard to find, check with your Lexus dealer before making a change.
Right oil and filter selection
Select a synthetic 0W-20 oil that meets API SN and ILSAC GF-5 (or newer) standards and pair it with a high-quality oil filter that meets Lexus specifications. Proper installation and torque on the drain plug are important to prevent leaks and ensure accurate oil level readings.
Seasonal and climate considerations
0W-20 performs well across a wide range of temperatures, making it the typical choice for cold starts and fuel efficiency. In extreme climates or under heavy-duty use, consult a Lexus service professional to confirm the recommended change interval and whether any adjustments to the oil specification are advisable for your circumstances.
Bottom line
For the 2015 RC 350 F Sport, the recommended oil is synthetic 0W-20 that meets API SN and ILSAC GF-5 or newer, with a typical replacement interval of about 10,000 miles under normal driving. Always verify the exact specification for your vehicle in the owner’s manual or on the oil filler cap.
Summary
In short, synthetic 0W-20 is the standard oil for the 2015 RC 350 F Sport. Use a quality oil and filter, follow the maintenance schedule, and rely on the vehicle’s oil life monitor to guide service timing. If in doubt, consult the official owner’s manual or a Lexus dealer.
