Keeping your 2023 GAS GAS MC 350F running smoothly and reliably requires regular oil changes. Performing this routine maintenance yourself is straightforward and helps protect your engine for maximum performance out on the track or trails. Below, we’ll guide you through each step–using the best practices and calling out specifics unique to your MC 350F.

Tools & Supplies Needed

• 1.0 liter Motorex Cross Power 4T 10W/50 full synthetic oil or OEM equivalent
• OEM oil filter
• Crush washer for drain bolt
• Drain pan
• 13mm socket and ratchet
• 8mm socket or Allen wrench
• Needle nose pliers
• Torque wrench
• Shop towels
• Measuring cup (for oil volume check)
• Contact cleaner (optional, for clean-up)
• Grease (for sealing O-rings)

Preparation: Safety & Setup

• Warm up the bike for several minutes. This helps the oil flow freely and brings any contaminants into suspension for a thorough drain.
• Place your motorcycle upright on a stable stand, with a clean workspace around you.

Step 1: Drain the Old Oil

• Locate the main oil drain bolt under the engine. Use a 13mm socket to loosen and remove it. Have the drain pan ready as oil will begin to flow out rapidly.
• Remove and inspect the crush washer on the bolt; if it’s damaged or excessively worn, replace it with a new one from your oil change kit.
• Wait until oil flow slows to a drip. Letting it drain fully ensures minimal contaminants are left in the engine.

Step 2: Remove the Oil Strainer

• With the oil nearly finished draining, locate the oil strainer bolt (13mm) on the engine side. Slowly remove it; some additional oil will drain here.
• Using needle nose pliers, gently extract the oil strainer from its housing. Wipe the strainer clean and check for any debris or metal shavings.
• If debris is found, consult your service manual or a certified technician—it might indicate internal engine wear.

Step 3: Replace the Oil Filter

• Open the oil filter cover (typically an 8mm bolt or Allen). Remove the old filter with a pick or clean fingers.
• Clean the inside of the filter housing with a shop towel. Lightly grease the O-ring on the new OEM filter if required.
• Install the new filter, ensuring correct orientation (consult the service manual illustration if unsure).
• Reinstall the cover and torque the bolts to the specification listed in your owner’s manual.

Step 4: Reinstall Components

• Reinstall the cleaned oil strainer and strainer bolt. Tighten to the specified torque.
• Reinstall the drain bolt with the new crush washer. Use a torque wrench according to the manufacturer’s specification to avoid over-tightening.

Step 5: Add Fresh Oil

• Remove the oil fill cap, then pour in 1.0 liter of Motorex Cross Power 4T 10W/50 full synthetic oil (as recommended for the MC 350F) using your measuring cup for accuracy.
• Replace the oil fill cap securely.

Step 6: Final Checks & Clean-up

• Start the engine and let it idle for two minutes. Check for any oil leaks from the drain bolt, filter cover, or strainer.
• Shut off the bike and let it sit for a minute. Check the oil level via the inspection window or dipstick, and top up if needed.
• Dispose of the old oil and filter according to your local hazardous waste regulations.

Model-Specific Call-Outs: 2023 GAS GAS MC 350F

• The MC 350F shares its engine architecture closely with KTM and Husqvarna 350 models from the same years, so oil change procedures and specs are almost identical.
• Always use the recommended 10W/50 full synthetic oil to ensure proper lubrication and cooling.
• Check for the latest torque specs and oil capacity in your owner’s manual, as small updates occur year-to-year. For 2023, the oil capacity with filter change is approximately 1.0 liter.
• Oil change interval: Replace the oil every 10–15 hours of riding under typical conditions. Under racing or extreme conditions, consider shorter intervals.
• Crush washer replacement is critical for leak prevention—never reuse an old one.
• If your bike has an aftermarket skidplate, a tool like the Bullet Proof Designs Oil Drain Tool can speed up the process and prevent messy spills by allowing oil to drain without skidplate removal.
