Keeping your Mitsubishi Delica's engine in peak condition is paramount for its longevity and performance. A fundamental aspect of this is understanding its specific needs, particularly when it comes to engine oil. This vital fluid lubricates, cools, and cleans the internal components of your engine, and getting the quantity and type right is crucial. This guide will delve into the specifics of the Delica's oil capacity and provide a comprehensive overview of the engine oil and filter change process.

Understanding Your Delica's Oil Capacity
The exact engine oil capacity for a Mitsubishi Delica can vary slightly depending on the specific model year, engine variant, and whether you are changing the oil and filter simultaneously. However, for many popular Delica models, particularly those equipped with the robust 4D56 engine, the typical oil capacity is around 5.5 to 6.0 litres when replacing the oil and filter. It is always best practice to consult your vehicle's owner's manual for the most accurate and definitive information pertaining to your specific Delica.
Why is the Correct Oil Capacity So Important?
Overfilling your engine with oil can be just as detrimental as underfilling it. Too much oil can lead to:
- Increased Oil Pressure: This can stress seals and gaskets, potentially causing leaks.
- Aeration of Oil: The crankshaft can whip the oil into a froth, reducing its lubricating properties and leading to increased wear.
- Catalytic Converter Damage: Excess oil can be burned in the combustion chamber, leading to fouled spark plugs and damage to the catalytic converter.
Conversely, insufficient oil levels can result in:
- Increased Friction and Heat: Vital engine components will not receive adequate lubrication, leading to overheating and premature wear.
- Engine Seizure: In severe cases, a lack of oil can cause the engine to seize, a catastrophic and expensive failure.
Therefore, accurately measuring and filling the correct amount of oil is a non-negotiable step in maintaining your Delica.
The Engine Oil and Filter Change: A Step-by-Step Guide
Performing a regular oil and filter change is one of the most effective ways to ensure your Delica's engine runs smoothly for years to come. While it might seem daunting, with the right tools and a methodical approach, it's a task most DIY enthusiasts can undertake.

Tools and Materials You'll Need:
Before you begin, gather the following:
- New engine oil (check your owner's manual for the correct viscosity and type, e.g., 10W-30 or 15W-40 for many diesel Delicas)
- New oil filter (ensure it's the correct part number for your Delica)
- Wrench or socket set (for the drain plug and oil filter housing)
- Oil filter wrench (strap wrench or cap wrench)
- Drain pan or bucket
- Funnel
- Rags or shop towels
- Gloves (to protect your hands)
- Jack and jack stands (if access to the drain plug is limited)
- Wheel chocks (for safety)
The Process:
- Warm Up the Engine: Start the engine and let it run for a few minutes to warm the oil. Warm oil flows more easily, allowing for a more complete drain. However, do not let it get excessively hot, as this can cause burns.
- Prepare the Vehicle: Park the Delica on a level surface. Engage the parking brake and place wheel chocks behind the rear wheels. If you need to lift the vehicle for better access, use a jack to raise it and then securely place jack stands under the appropriate jacking points. Never work under a vehicle supported only by a jack.
- Locate the Drain Plug: Slide under the vehicle and locate the oil sump pan, typically at the bottom of the engine. You'll find a single bolt on the lowest point of the sump – this is the drain plug.
- Position the Drain Pan: Place your drain pan directly beneath the drain plug.
- Remove the Drain Plug: Using the appropriate wrench or socket, carefully loosen and remove the drain plug. Be prepared for the hot oil to gush out. Allow the oil to drain completely. This can take several minutes.
- Replace the Drain Plug: Once the oil has finished draining, clean the drain plug and the area around the drain hole. Inspect the drain plug's washer; if it looks worn or damaged, it's advisable to replace it. Reinstall the drain plug and tighten it securely, but do not overtighten, as this can strip the threads.
- Locate the Oil Filter: The oil filter's location can vary, but on many Delica models, it's often found on the side or underside of the engine block. Consult your owner's manual if you have trouble finding it.
- Remove the Old Oil Filter: Place the drain pan under the oil filter, as some residual oil will likely spill out. Use an oil filter wrench to loosen the filter. Once loose, unscrew it by hand.
- Prepare the New Oil Filter: Before installing the new filter, take a small amount of new engine oil on your finger and lightly coat the rubber gasket on the new filter. This helps create a good seal and prevents the gasket from sticking.
- Install the New Oil Filter: Carefully screw the new oil filter onto the engine block by hand. Once the gasket makes contact with the engine, tighten it an additional three-quarters to one full turn by hand. Again, do not overtighten. Some filters will have specific instructions printed on them – follow those if available.
- Add New Engine Oil: Open the bonnet and locate the oil filler cap (usually marked with an oil can symbol). Remove the cap and insert your funnel. Carefully pour in the correct amount of new engine oil. Start with slightly less than the specified capacity (e.g., if it's 5.5 litres, add 5 litres initially).
- Check the Oil Level: Replace the oil filler cap. Start the engine and let it run for a minute or two, allowing the new oil to circulate and fill the new filter. Turn off the engine and wait a few minutes for the oil to settle back into the sump. Pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again. Check the oil level against the markings on the dipstick. Add more oil incrementally if needed, rechecking the level each time, until it reaches the 'Full' or 'Max' mark. Do not overfill.
- Final Checks: Once the correct level is achieved, ensure the oil filler cap and dipstick are securely in place. Check under the vehicle for any leaks around the drain plug and the oil filter.
- Dispose of Old Oil and Filter: Properly dispose of the used engine oil and filter. Most local garages or recycling centres have facilities for this. Never pour used oil down drains or into the environment.
Frequently Asked Questions (FAQs)
Q1: How often should I change the oil and filter on my Delica?
A: The recommended interval can vary, but for many Delica models, a change every 5,000 to 10,000 kilometres or every 6 to 12 months, whichever comes first, is a good general guideline. Always refer to your owner's manual for the manufacturer's specific recommendations.
Q2: What type of oil should I use in my Delica?
A: This is critical. Most diesel Delicas benefit from a good quality diesel-specific engine oil with the correct viscosity rating (e.g., 10W-30, 15W-40, or 5W-40, depending on climate and engine type). Always check your owner's manual for the precise specification, including any API or ACEA ratings required.
Q3: Can I use a different brand of oil filter?
A: Yes, as long as the replacement filter is specifically designed for your Delica model and meets or exceeds the original equipment manufacturer's specifications. Reputable aftermarket brands are generally safe to use.

Q4: My Delica is older, does that change the oil I should use?
A: For older engines, particularly those that may have developed minor oil consumption or leaks, some owners opt for oils with slightly higher viscosity (e.g., moving from 10W-30 to 15W-40 in warmer climates) or those formulated with seal conditioners. However, stick to the manufacturer's recommendation unless advised otherwise by a qualified mechanic.
Q5: What if I can't find the oil capacity for my specific Delica model?
A: The most reliable source is your vehicle's owner's manual. If you don't have it, you can often find digital versions online by searching for "Mitsubishi Delica [your model year] owner's manual". Alternatively, a good auto parts supplier or a Mitsubishi dealership can often provide this information.
Conclusion
Understanding and adhering to your Mitsubishi Delica's engine oil capacity and performing regular oil and filter changes are fundamental to its health and performance. By following these guidelines, you can ensure your trusty Delica continues to serve you well on all your adventures, keeping its engine running smoothly and reliably.
