Complete Oil Specifications
Your 2023 Genesis GV80 with the 2.5T turbocharged four-cylinder requires 0W-30 full synthetic oil meeting API SN. The G25DT engine is Genesis’s advanced turbocharged unit combining direct injection with dual continuously variable valve timing (CVVT) for a balance of power and efficiency in this luxury SUV.
Quick Reference

| Normal Interval | 8000 miles |
Why 0W-30 for the G25DT Turbo
The G25DT is a turbocharged direct-injection engine where the turbocharger bearings demand reliable oil flow at both cold start and high-load conditions. Genesis specifies 0W-30 — not the more common 0W-20 — because the slightly higher high-temperature viscosity (30 vs 20) provides a better protective film at the turbocharger shaft, which can reach temperatures well above the combustion chamber.
Using incorrect oil will:
- ❌ Thin out too quickly at the turbo shaft, causing accelerated bearing wear
- ❌ Reduce protection for dual CVVT cam actuators during cold starts
- ❌ Risk LSPI (Low-Speed Pre-Ignition) in direct-injection conditions without proper API SN certification
Genesis-Approved Oil Brands
-
✅ Genesis Genuine Motor Oil 0W-30
-
✅ Mobil 1 Extended Performance 0W-30
-
✅ Pennzoil Ultra Platinum Full Synthetic 0W-30
-
✅ Castrol Edge Full Synthetic 0W-30
-
✅ Shell Helix Ultra 0W-30
Use only oils meeting API SN or higher. The 0W-30 viscosity grade is non-negotiable for this engine — do not substitute 0W-20 or 5W-30.
Severe Service Check
Use the 4000-mile interval if you:
- Frequently tow or carry maximum passenger/cargo loads
- Drive primarily in urban stop-and-go traffic
- Operate in extreme temperatures or high-altitude conditions
- Use the vehicle for track or performance driving

Drain Plug Torque: 26 ft-lbs
Replace the drain plug washer at every oil change — Genesis uses a soft aluminum crush washer.

Pro Tip: The GV80 holds 6.6 quarts — more than many owners expect from a 2.5L four-cylinder. This large sump volume is intentional: Genesis designed it to support longer 8,000-mile intervals under normal driving conditions.
FAQs
What oil does a 2023 Genesis GV80 2.5T take?
0W-30 full synthetic meeting API SN or higher.
How many quarts does the GV80 2.5T need?
6.6 quarts with a new filter, 6.3 without.
Can I use 0W-20 instead of 0W-30?
No. Genesis explicitly specifies 0W-30 for the G25DT turbo engine. Using 0W-20 will result in insufficient high-temperature viscosity at the turbocharger bearings.
Is synthetic oil required?
Yes. Full synthetic is required to meet API SN standards and achieve the 8,000-mile service interval.
How often should I change the oil?
Every 8000 miles under normal driving conditions. Genesis’s Maintenance Reminder System will alert you based on actual driving patterns.
