How to Change the Oil in a 2023 GAS GAS MC-E 5 — MotoSport.com Guide

Shop parts for a 2023 GAS GAS MC-E 5 Dirt Bike.

The 2023 GAS GAS MC-E 5 is an all-electric motocross bike, so it does not use engine oil in the traditional sense required for combustion engines. However, for the benefit of those seeking routine maintenance, it's important to clarify what maintenance you should perform and to highlight oil-related maintenance considerations for similar GAS GAS models. This post also outlines the process for changing oil on comparable GAS GAS models in case you have multiple bikes in your garage.

Do You Need to Change the Oil in the MC-E 5?

No engine oil change is required for the electric 2023 GAS GAS MC-E 5 because it uses a brushless electric motor, not an internal combustion engine. Regular oil changes are only necessary for gas-powered motorcycles, not for all-electric bikes like the MC-E 5.

Related Maintenance for the MC-E 5

  • Check and maintain battery charge and connections regularly.
  • Inspect the drive chain and lube with suitable chain lubricant as needed.
  • Check front fork oil by servicing suspension per manufacturer guidelines (recommended every 20-40 hours for fork oil changes, depending on riding conditions and usage).
  • Inspect and replace brake fluid as required by manufacturer's service intervals.

If you also ride a gas-powered GAS GAS model, here is a detailed, proprietary guide for routine oil changes based on MotoSport.com expertise and GAS GAS factory recommendations.

Tools and Supplies Needed

  • MOTOREX Cross Power 4T 10W/50 full synthetic oil (amount varies per model)
  • OEM oil filter (for four-stroke engines)
  • Oil drain bolt crush washer
  • Socket wrench set (with correct sized sockets for drain plug and filter cover)
  • Drain pan
  • Torque wrench
  • Clean shop rags and gloves
  • Contact or brake cleaner
  • Needle nose pliers (optional–for removing screens)
  • Funnel

Step-by-Step Oil Change Procedure for GAS GAS Four-Stroke Models

  1. Warm up the bike. Run the engine for 2-3 minutes to circulate oil and suspend contaminants for draining. Shut off and ensure the bike is upright.
  2. Remove the skid plate (if equipped) and locate the oil drain plug at the bottom of the engine.
  3. Place a drain pan under the plug. Carefully remove the drain plug using a socket wrench. Allow all oil to fully drain.
  4. Clean the drain plug and replace the crush washer. Inspect the oil for metal particles or debris, which can indicate engine wear. Minor metallic shavings are normal, but large chunks are cause for concern.
  5. Inspect and clean the oil screen. Remove it as per your model's manual. Clean with contact cleaner and reinstall. Be careful with O-rings–replace if damaged or flattened. Lubricate O-rings before reinstalling the screen to prevent leaks.
    Note: For some models, alignment of the oil screen is critical for proper oil flow. Use needle nose pliers if necessary for installation and to avoid letting debris bypass the screen.
  6. Remove the oil filter cover and old filter. Use a clean rag to wipe sealing surfaces. Inspect O-rings–a damaged seal can cause leaks. Replace the filter with a new OEM one.
  7. Reinstall the drain plug and torque to manufacturer spec (e.g., 14.8 ft-lbs for most current GAS GAS 250/350 models; check your manual for specifics). Avoid over-tightening.
  8. Add fresh oil. Use a funnel to avoid spills. Pour in the required amount:
    • MC 250F/350F: Typically about 1.0 liter. Check your owner's manual for exact capacity.
    • MC 85: About 0.5 liter (85cc models use gear oil, not engine oil, for transmission).
  9. Reinstall the oil filter cover and torque bolts to spec (often 7-11 ft-lbs).
  10. Check the oil level. Start the engine, let it idle for a minute, shut off, then check again with the bike upright. Add oil if necessary.
  11. Dispose of old oil and filter responsibly. Take used oil to a recycling center.

Call-outs for 2023 GAS GAS Models

  • MC-E 5: No engine oil change is required. Focus on battery, chain, fork oil, and brake fluid maintenance.
  • MC 85: Remove or reposition the rear brake pedal for access to the drain plug. Use 500cc of specified transmission/gear oil (Maxima MTL or equivalent).
  • 250F/350F Four-Stroke: Always use a new crush washer. Carefully align the oil screen. Avoid removing the oil pressure bypass spring and ball (often mistaken for a drain plug).

Common Mistakes and Model-Specific Tips

  • Never overfill the oil – check specs for your year and model.
  • Avoid removing the oil pressure bypass plug; this is NOT for oil changes.
  • Inspect all O-rings and replace if they are flattened or damaged to prevent leaks.
  • Always torque bolts per GAS GAS factory specs to avoid stripping threads or causing oil leaks.
  • Use only recommended oil for your model to ensure longevity and proper function.

Conclusion

For the 2023 GAS GAS MC-E 5, regular maintenance focuses on non-oil items. For other GAS GAS models, follow the outlined steps using OEM quality parts and proper torque specs for a smooth, reliable ride. Always reference your specific model's owner's manual for up-to-date procedures and recommended intervals.
