Why 0W-20 is Critical for This Engine
The J35Y6 combines Honda’s proven 3.5L SOHC V6 architecture with direct injection and i-VTEC variable valve timing on both cam banks. As a unibody truck platform, the Ridgeline sees higher sustained loads than a typical SUV — the oil must maintain film strength under trailer towing and bed-loading conditions. Honda’s 0W-20 specification is a full synthetic formulation precisely calibrated for the J35Y6’s high-volume oil passages and VTEC hydraulic circuits, providing both cold-start protection and high-temperature shear stability.
Using thicker oil will:
- ❌ Increase hydraulic resistance in VTEC solenoid passages, causing delayed cam phasing
- ❌ Reduce fuel economy, particularly at highway speeds where the J35Y6 runs lean
- ❌ Add unnecessary load on the oil pump during cold starts
Honda-Approved Oil Brands
-
✅ Honda Genuine Motor Oil 0W-20
-
✅ Mobil 1 Advanced Fuel Economy 0W-20
-
✅ Castrol EDGE 0W-20
-
✅ Pennzoil Platinum 0W-20
-
✅ Valvoline Advanced Full Synthetic 0W-20
All oils must meet API SP (or SN Plus) and ILSAC GF-6A. Full synthetic is required — synthetic blend is not sufficient for Honda’s extended Maintenance Minder intervals.
Severe Service Check
Use the 5000-mile interval if you:
- Tow a trailer or haul heavy payloads regularly (this is the most common trigger for Ridgeline owners)
- Use the truck bed for frequent heavy cargo with engine lugging
- Drive off-road on unpaved roads
- Experience frequent cold starts in temperatures below 10°F
Installation Details
Drain Plug Torque: 29 ft-lbs ⚠️ The Ridgeline’s oil pan is aluminum. Replace the crush washer at every service — reusing it risks a slow drip that’s hard to detect before damage occurs.
OEM Filter: Honda 15400-PLM-A02
Aftermarket Filters:
-
Mobil 1 M1-110A
-
K&N HP-1010
-
WIX 51365
Pro Tip: The Ridgeline’s dual-action tailgate and in-bed trunk make it easy to store a drain pan during DIY oil changes. The drain plug is accessible without a lift on a flat surface, but the filter is tight — use a compact cap-style filter wrench for clean removal.
FAQs
What oil does a 2023 Honda Ridgeline 3.5L V6 take? 0W-20 full synthetic oil meeting API SP and ILSAC GF-6A standards.
How many quarts does it need? 5.0 quarts with a new filter, 4.6 without.
Can I use 5W-30 for towing? No. Honda does not recommend thicker oil for towing. The J35Y6’s oil system is designed for 0W-20, and the factory oil cooler (AWD models) provides sufficient thermal management at rated tow capacity (5,000 lb).
Is synthetic oil required? Yes. Full synthetic is mandatory for the 2023 Ridgeline to meet Honda’s 7,500-mile Maintenance Minder intervals and protect the VTEC system adequately.
How often should I change the oil? Follow Honda Maintenance Minder — do not exceed 7500 miles or 12 months. Tow frequently? The system will shorten the interval automatically.
