Complete Oil Specifications
Your 2022 Mitsubishi Eclipse Cross with the 1.5T 4B40 engine requires 0W-20 full synthetic oil meeting API SP / ILSAC GF-6A. The 4B40 is Mitsubishi’s turbocharged four-cylinder featuring direct injection and S-AWC (Super All-Wheel Control) integration for confident all-weather traction.

Why 0W-20 for the 4B40 Turbo
The 4B40’s turbocharger and direct injection system demand low-viscosity oil for rapid cold-start flow to the turbo shaft bearings. Despite its small 1.5L displacement, the 4B40 produces over 150 hp through boost pressure — loading the turbo bearings significantly under acceleration. 0W-20 full synthetic provides the right balance of cold-start fluidity and high-temperature film stability for this application.
Using incorrect oil will:
- ❌ Slow oil delivery to turbo bearings at cold start, increasing shaft wear
- ❌ Increase friction losses and reduce the 4B40’s fuel economy
- ❌ Risk LSPI events without the GF-6A anti-LSPI chemistry

Severe Service Check
Use the 3750-mile interval if you:
- Make frequent short trips under 5 miles where oil never reaches full operating temperature

- Drive in extreme cold below 0°F or extreme heat above 95°F
- Use S-AWC in demanding off-road or winter conditions frequently

Pro Tip: The 4B40 holds only 4.5 quarts — it’s easy to accidentally overfill if you pour without checking. Add 4.0 quarts, check the dipstick, then top up to the full mark. The dipstick is located on the driver’s side of the engine bay.
FAQs
What oil does a 2022 Mitsubishi Eclipse Cross take?
0W-20 full synthetic meeting API SP / ILSAC GF-6A.
How many quarts does the Eclipse Cross 1.5T need?
4.5 quarts with a new filter, 4.3 without.
Can I use 5W-30 for extra protection in summer?
Mitsubishi specifies 0W-20 for the 4B40. Modern full synthetic 0W-20 provides adequate summer protection. Only use an alternative viscosity if 0W-20 is completely unavailable.
Is synthetic oil required?
Yes, full synthetic is required to meet API SP / GF-6A standards for the 4B40 turbo.
How often should I change the oil?
Every 7500 miles under normal conditions, or every 6 months — whichever comes first.
