The 2015 Ford Explorer with the 3.5-liter V6 typically requires SAE 5W-20 engine oil, with full synthetic preferred. A synthetic-blend that meets the same viscosity is acceptable if full synthetic isn’t available.
This article explains the recommended oil type for the engine, typical capacity and change intervals, and practical tips for maintenance to help you keep the V6 running smoothly.
Recommended oil type
Choosing the right oil starts with the correct viscosity and oil family. For the 3.5L V6 in the 2015 Explorer, use SAE 5W-20. Full-synthetic is preferred for better protection and longer drain intervals, but a high-quality synthetic-blend 5W-20 is also acceptable if needed. Always confirm the exact specification on the vehicle’s owner manual or the under-hood oil label.
The following points summarize the key oil requirements for this engine:
- Viscosity: SAE 5W-20
- Oil type: Full synthetic preferred; synthetic-blend acceptable
- Standards: Oil should meet modern automotive standards and be appropriate for a gasoline V6 engine
In practice, sticking with 5W-20 full synthetic ensures optimum cold-start protection and consistent performance across seasons. If towing or consistently hot conditions are a factor, follow the manual’s guidance and consult a dealership or qualified technician for any deviation.
Oil capacity and change interval
Knowing how much oil the engine holds and when to change it helps plan maintenance. The 3.5L V6 in the 2015 Explorer generally holds about 6 quarts (roughly 5.7 liters) of oil with a filter replacement, but exact capacity can vary by engine variant and drain procedure.
The following points cover typical change intervals and capacity:
- Oil capacity: Approximately 6 quarts (5.7 L) with filter
- Change interval: About every 7,500 miles when using synthetic oil under normal driving; about every 5,000 miles if using conventional oil or under severe service (extreme temperatures, heavy towing, or frequent short trips)
- Note: Always reference the owner’s manual for the precise recommendation on your vehicle’s configuration
Regularly scheduled changes with the recommended oil help protect the engine’s bearings and overall performance. If you’re unsure about which exact interval applies to your driving conditions, err on the side of more frequent changes, especially in harsh climates or heavy-use scenarios.
Practical tips for maintenance
If you plan to perform oil changes yourself or want to talk with a shop, these practical tips can help ensure you get it right the first time.
- Warm up the engine briefly to loosen oil, then turn off and safely raise the vehicle if needed.
- Place a drain pan under the oil pan and remove the drain plug to allow used oil to drain completely.
- Remove and replace the oil filter with a new one of appropriate specification.
- Reinstall the drain plug and add the recommended amount of 5W-20 oil, using a high-quality oil filter.
- Check the oil level with the dipstick after a brief engine run and recheck once the oil has settled.
- Dispose of used oil and filter at an approved recycling facility.
For those who prefer professional service, providing the above information helps ensure the service matches the engine’s needs. Always use the correct oil grade and a compatible filter to maintain warranty coverage and engine health.
Summary
In short, the 2015 Ford Explorer's 3.5 L V6 generally requires SAE 5W-20 engine oil, with full synthetic preferred. The engine holds about 6 quarts of oil, and the recommended change interval is roughly 7,500 miles with synthetic oil (5,000 miles if using conventional oil or under severe service). Always verify exact specifications in the owner’s manual or on the under-hood label, and follow maintenance guidance based on your climate and driving conditions.
