The 2015 Nissan Frontier does not use a 2.4-liter engine; the four‑cylinder option is a 2.5-liter QR25DE. It requires 5W-30 engine oil (conventional or synthetic) and about 4.6 quarts with a filter. Always verify the exact specification for your vehicle in the owner’s manual or on the underhood placard.
Engine options in the 2015 Frontier
Understanding which engines were offered helps determine the correct oil guidance. In 2015, the Frontier was available with two gasoline engines: a 2.5L inline-four and a 4.0L V6. There was no 2.4L option in that model year.
- 2.5L QR25DE inline-four
- 4.0L V6 VQ40DE
Both engines share the general approach to oil, but exact capacities and maintenance intervals can vary by engine. Always consult the specific manual for your VIN.
Oil specifications for the 2.5L QR25DE
For the 2.5L QR25DE, Nissan specifies an engine oil with a viscosity of 5W-30. You may use conventional or synthetic oil as long as it meets API SN or newer and ILSAC GF-5 (or newer) standards.
- Viscosity: 5W-30
- Oil type: conventional or synthetic acceptable
- Standards: API SN (or newer) and ILSAC GF-5 (or newer)
Choosing synthetic oil can offer better protection in extreme temperatures and longer intervals, but always follow the manufacturer’s guidance for your climate and driving conditions.
Oil capacity and service notes
When performing an oil change on the 2.5L QR25DE, plan for about 4.6 quarts of oil with the filter installed. Exact capacity can vary slightly depending on the filter type and drainage procedure.
- Oil capacity (with filter): approximately 4.4–4.8 quarts
- Oil filter: replace at every oil change
Always verify the precise capacity for your specific vehicle and engine variant using the owner’s manual or the service placard under the hood.
Summary
In short, the 2015 Nissan Frontier’s four-cylinder option uses 5W-30 oil, either conventional or synthetic, with an approximate capacity of 4.6 quarts (with filter). There is no 2.4L engine in the 2015 Frontier; if you own a Frontier, confirm your exact engine and follow the manual’s oil grade, standards, and capacity recommendations for the best results.
