Engine Oil Change Procedure

- Locate Drain Plug: Identify the engine oil drain plug, typically located at the lowest point of the engine's oil pan.
- Drain Old Oil: Using the appropriate wrench, carefully loosen and remove the drain plug. Allow all the old oil to drain completely into the drain pan. This may take several minutes.
- Replace Drain Plug: Once drained, clean the drain plug and replace its washer (if applicable). Reinstall the drain plug and tighten it to the torque specification provided in your motorcycle's owner's manual. Do not overtighten.
- Remove Old Oil Filter (if applicable): If your motorcycle has an external oil filter, use an oil filter wrench to remove it. Be prepared for additional oil to drain from the filter housing.
- Install New Oil Filter (if applicable): Apply a thin film of new engine oil to the rubber gasket of the new oil filter. Install the new filter and tighten it according to the manufacturer's specifications (usually hand-tight plus a quarter to half turn, or to a specific torque).
- Add New Oil: Locate the oil fill cap on your engine. Using a funnel, slowly pour the recommended amount of Maxima Racing Oils Pro Plus+ 10w30 Synthetic Motorcycle Engine Oil into the engine. Refer to your motorcycle's owner's manual for the exact oil capacity.
- Check Oil Level: After adding the oil, replace the fill cap. Start the engine and let it run for a few minutes to circulate the new oil. Turn off the engine and wait a few minutes for the oil to settle. Check the oil level using the dipstick or sight glass, ensuring it is within the recommended range. Add more oil if necessary, but avoid overfilling.
- Inspect for Leaks: Visually inspect the drain plug and oil filter area for any signs of leaks.
- Dispose of Used Oil: Transfer the used oil from the drain pan into a sealed container and take it to an approved oil recycling facility.
Maintenance
Routine Checks
- Regular Oil Level Check: Periodically check your engine oil level, especially before long rides. Maintain the oil level between the minimum and maximum marks on your dipstick or sight glass.
- Oil Change Intervals: Adhere to the oil change intervals recommended by your motorcycle manufacturer. Maxima Pro Plus+ is a high-performance synthetic oil, but regular changes are crucial for engine longevity.
- Observe Oil Condition: While checking the level, observe the oil's color and consistency. Extremely dark, milky, or gritty oil may indicate a problem and should be changed immediately.
Storage
Store Maxima Racing Oils Pro Plus+ in its original sealed container in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the cap is tightly sealed to prevent contamination.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Oil Level | Oil consumption, leaks, or insufficient fill. | Check for leaks. Top up oil to the correct level. If consumption is excessive, consult a mechanic. |
| Rough Shifting / Clutch Slippage | Incorrect oil type, worn clutch, or low oil level. | Ensure you are using Maxima Pro Plus+ 10w30 (JASO MA compliant). Check oil level. If issues persist, inspect clutch components. |
| Engine Overheating | Low oil level, old oil, or other engine issues. | Check oil level and condition. Perform an oil change if due. If problem persists, seek professional diagnosis. |
| Oil Leakage after Change | Drain plug not tightened correctly, damaged drain plug washer, or improperly installed oil filter. | Re-tighten drain plug to spec, replace washer, or re-install oil filter correctly. |
