How Much Oil Does a Malibu M5 or M6 Engine Need?

For an 8-quart oil change, purchase:

• One 5-quart bottle of Mobil 1 Full Synthetic 5W-30

• The correct Malibu engine oil filter for your engine

Always confirm the exact oil capacity for your engine and check the oil level using the manufacturer's procedure. Do not overfill.

Important: Select Malibu M6Di Engines Require 0W-40

Some Malibu Monsoon M6Di engines are subject to an updated manufacturer oil specification requiring 0W-40 Full Synthetic engine oil instead of 5W-30.

Based on the supplied service information, M6 engines manufactured between March 1, 2021, and May 31, 2024, may be affected by this change.

For affected engines, do not continue using 5W-30 when the applicable manufacturer bulletin specifies 0W-40.

Before ordering, verify your engine model, production date, and current oil specification.

Unsure which oil your M6Di requires? Contact Bakes Marine with your boat's Hull Identification Number (HIN) and engine information for assistance identifying the correct service parts.

Malibu Monsoon LT4 Oil Requirements

Do not use this 5W-30 oil in Malibu Monsoon LT4 engines that specify 0W-40.

The supercharged Malibu Monsoon LT4 uses a different engine oil specification. Select the manufacturer-approved 0W-40 Full Synthetic engine oil and correct LT4 oil filter when servicing this engine.

Marine Engine Oil Change Intervals

For applicable Malibu M-Series engines, the supplied maintenance guidance identifies a standard engine oil and filter service interval of every 50 operating hours or annually, whichever comes first.

Certain severe or extreme operating conditions may require oil and filter changes as frequently as every 25 operating hours, depending on the applicable maintenance schedule.

Examples of demanding operating conditions include:

• Extended operation with heavy ballast loads
• Frequent low-speed, high-load wakesurfing
• Extended idling
• High-elevation operation
• Commercial or other severe-duty use

Always follow the maintenance interval specified in your engine owner's manual and current manufacturer service information.
