How to Find the Right Oil Capacity:
1. Consult the Owner's Manual: The most reliable source is the owner's manual for your specific Isuzu vehicle or equipment.
2. Check the Oil Fill Cap: The oil fill cap (usually on the engine's valve cover) might have the oil capacity printed on it.
3. Look for an Engine Information Plate: There's often a plate on the engine block or nearby that provides engine details, including the oil capacity.
4. Contact a Mechanic or Isuzu Dealer: A mechanic familiar with Isuzu engines or a local Isuzu dealer can provide the correct oil capacity for your specific engine.
Important Note: Always use the correct type and amount of oil recommended by Isuzu for your engine. Using the wrong oil can damage your engine.
