The 2008 Mitsubishi Endeavor uses SAE 5W-30 motor oil, typically available as a synthetic blend or full synthetic, and it holds about 5 quarts (roughly 4.7 liters) with a new filter. Oil used should meet API SN or newer specifications.
The Endeavor's 2008 model year is equipped with a 3.8-liter V6 engine, and Mitsubishi generally specifies 5W-30 oil for most climates. This guidance appears in the owner’s manual and is echoed by service professionals. For precise guidance, especially in extreme temperatures or unusual driving conditions, always consult the manual or a Mitsubishi dealer.
Oil specifications
Grade and standards
Before listing recommended oil types, here is a concise guide to the standards that meet the Endeavor’s requirements.
- SAE 5W-30 motor oil that meets API SN or newer (conventional, synthetic-blend, or full synthetic).
- Oil that also meets ILSAC GF-5 standards is acceptable for this engine.
- Full synthetic 5W-30 is a common choice for improved performance and potentially longer drain intervals.
In practice, choose a reputable brand that clearly states API SN or newer and ILSAC GF-5 compliance, and select 5W-30 for the 3.8L V6 in most climates.
Capacity and service interval
Capacity and maintenance tips
Before listing estimated capacity and intervals, note the following figures and guidance for the Endeavor’s engine.
- Oil capacity (with filter): approximately 5 quarts (about 4.7 liters).
- Recommended oil-change interval: around every 5,000 miles (8,000 kilometers) under normal driving with conventional oil; if using synthetic oil, intervals can be longer (often 7,500–10,000 miles) depending on driving conditions and manufacturer guidance.
- Always replace the oil filter with every oil change.
For exact intervals and any climate-specific recommendations, refer to the owner’s manual or the service reminder sticker on the vehicle.
Summary
In short, a 2008 Mitsubishi Endeavor typically takes SAE 5W-30 motor oil meeting API SN or newer standards, with an oil capacity of about 5 quarts (4.7 liters) including the filter. Use a conventional, synthetic-blend, or full-synthetic 5W-30 and follow the manual’s maintenance schedule to keep the engine running smoothly.
