Capacity by Engine Option

Oil Change Interval

For the 6.6L V8 gasoline engine, Isuzu recommends the following oil change intervals:

• Normal Duty: Every 7,500 miles or 12 months, whichever comes first.
• Severe Duty: Every 3,000 miles or 3 months, whichever comes first. Severe duty includes conditions like frequent short trips, extensive idling, towing, or operating in dusty conditions.

Drain Plug Torque

For the 6.6L V8 gasoline engine, the oil drain plug torque specification is 18 lb-ft (25 Nm). Always replace the drain plug gasket/crush washer to ensure a proper seal and prevent leaks. Consult the dealer for the correct crush washer part number.

How to Change the Oil (6.6L V8 Gas)

1. Warm up the engine to operating temperature, then shut it off. This helps the oil drain more completely.
2. Locate and place a suitable drain pan beneath the oil drain plug, typically on the passenger side of the oil pan.
3. Remove the oil drain plug with an appropriate wrench and allow all the old oil to drain completely. Inspect the drain plug and replace the crush washer.
4. Reinstall the drain plug and torque to 18 lb-ft (25 Nm).
5. Locate the oil filter, usually near the front of the engine, above the drain plug. Prepare for some oil spillage when removing the old filter.
6. Remove the old oil filter. Apply a thin coat of new oil to the rubber gasket of the new filter.
7. Install the new oil filter and tighten it by hand until snug, then an additional 3/4 to 1 full turn. Do not overtighten with a wrench.
8. Locate the oil fill cap on top of the engine and remove it.
9. Add 7.0 quarts of fresh 0W-20 engine oil, meeting dexos1 Gen2 or Gen3 specifications.
10. Reinstall the oil fill cap.
11. Start the engine and run for a few minutes while checking for any leaks around the drain plug or oil filter.
12. Shut off the engine, wait a few minutes for the oil to settle, then check the oil level on the dipstick and top off if necessary.

Common Issues / Tips

• Diesel Engine Information: This article primarily focuses on the 6.6L V8 gasoline engine. For the 5.2L Diesel (4HK1) engine, oil capacity, type, and filter specifications are significantly different and require specific diesel engine oil (e.g., CK-4 or FA-4) and filters. Always consult your owner's manual or an Isuzu dealer for precise information regarding the diesel powertrain.
• Correct Oil Specification: Using oil that does not meet the dexos1 Gen2 or Gen3 specification for the gasoline engine can lead to premature wear and potential engine damage. These specifications are crucial for modern engines with technologies like direct injection. Always look for the 'dexos' logo on the oil bottle.
• Filter Quality: While aftermarket filters are listed, always ensure you are using a high-quality filter from a reputable brand to ensure proper filtration and engine protection. Inferior filters can lead to oil flow restrictions or inadequate contaminant removal.
• Check for Leaks: After every oil change, visually inspect around the oil filter and drain plug area after running the engine. Even minor drips can indicate an issue with the filter seal or drain plug washer.
