10w40
For a Suzuki 750 King Quad, it is recommended to use a high-quality gear oil specifically designed for final drives. A common choice is 80W-90 or 75W-90 hypoid gear oil, which provides the necessary protection and lubrication for the differential and final drive system. Always check the owner's manual for specific recommendations and ensure the oil meets the required specifications.
To check the oil on a Suzuki 750 King Quad, first ensure the vehicle is on a level surface and the engine is off. Locate the dipstick, usually found on the oil filler cap, remove it, and wipe it clean with a cloth. Reinsert the dipstick without screwing it in, remove it again, and check the oil level against the markings. If the oil level is low, add the appropriate oil type until it reaches the correct level.

To add front differential fluid to a Suzuki King Quad 300, locate the front differential housing, which is typically situated near the front axle. Remove the fill plug, usually found on the top or side of the differential case. Use a funnel to pour the appropriate type of differential fluid into the housing until it reaches the fill level, then securely replace the fill plug. Always refer to the owner's manual for specific fluid specifications and maintenance recommendations.
