Parts for your 2008 Mitsubishi Lancer-Engine oil

2008 Mitsubishi Lancer engine oil — what it does and when to change it

Engine oil is absolutely relevant to the 2008 Mitsubishi Lancer. Mitsubishi’s 2008 Lancer (CJ) Owner’s Manual specifies engine oil grades and capacities for the 4B11/4B12 petrol engines, and the service schedule calls for routine oil and filter changes. Technical references: Mitsubishi Motors 2008 Lancer Owner’s Manual (CJ series), Mitsubishi Australia Service and Warranty Booklet, and Mitsubishi Workshop Manual for 4B1 engines.

For this Lancer, engine oil keeps the four‑cylinder humming by reducing friction, carrying away heat, suspending contaminants, protecting against corrosion, and helping seal the piston rings. That all adds up to smoother running, better fuel economy, and a longer‑lived engine.

Recommended oil types (check the oil cap and owner’s book for your exact variant):

• Petrol 2.0/2.4 (4B11/4B12): Typically SAE 5W‑30 meeting API SM/SN or ILSAC GF‑4/GF‑5, some markets allow 0W‑20 for fuel economy.
• Ralliart turbo (4B11T): High‑quality full‑synthetic 5W‑30 or 5W‑40 meeting API SN or better.
• Diesel models (where fitted): Low‑SAPs ACEA C3 5W‑30.

Typical capacities: around 4.3–4.6 L for the petrol engines, and roughly 5+ L for the diesel, including the filter. Always verify for the exact engine code.

Service timing in Australia and New Zealand is straightforward. Under normal use, aim for every 15,000 km or 12 months, whichever comes first. If the Lancer does short trips, lots of stop‑start, dusty roads, hot towing, or spirited driving, halve that to about 7,500 km. Turbo models benefit from the shorter interval due to higher oil stress.

Good habits make a big difference:

1. Check the dipstick monthly, top up to the upper mark with the correct grade.
2. Replace the filter at every oil change and use a new sump washer.
3. Warm the engine before draining, then torque the drain plug correctly.
4. Watch for rising oil level (possible fuel dilution) or rapid consumption — address promptly.
5. Dispose of used oil and filters responsibly at a recycling point.

Following the manual’s spec and these intervals keeps the 2008 Lancer running sweet, protects the timing components, and helps avoid costly wear. If in doubt about grade or capacity, use the owner’s manual for the exact VIN/engine or check the under‑bonnet label.

Popular questions

What oil grade should a 2008 Mitsubishi Lancer use?
Most 2.0/2.4 petrol CJ Lancers run well on SAE 5W‑30 meeting API SM/SN or ILSAC GF‑4/GF‑5. Some markets permit 0W‑20 for economy. Turbo Ralliart models prefer a full‑synthetic 5W‑30 or 5W‑40. Always match what’s on the oil cap and in the owner’s manual.

How often should the oil be changed?
Under normal Aussie/Kiwi driving, every 15,000 km or 12 months. For short trips, stop‑start, dusty conditions, or turbo use, tighten it to about 7,500 km. Fresh oil and a new filter each time keeps the 4B1 engines healthy.

How much oil does it take?
Petrol engines are typically around 4.3–4.6 litres with the filter. Diesel variants are usually just over 5 litres. After refilling, run the engine briefly, wait a minute, and recheck the dipstick to fine‑tune the level.
