How to Check and Change Kohler Engine Oil
Step 1: Gather Your Supplies
To change your Kohler engine oil, you’ll need:
- Correct oil type (refer to the Kohler engine oil chart)
- Oil filter (if applicable)
- Wrench or oil filter removal tool
- Drain pan
- Funnel
- Clean rag or paper towel
Step 2: Warm Up the Engine
Run the engine for a few minutes to warm up the oil. This helps it drain more efficiently.
Step 3: Drain the Old Oil
- Place a drain pan under the engine.
- Remove the oil drain plug and let the oil drain completely.
- If your engine has an oil filter, replace it at this stage.
Step 4: Refill with Fresh Oil
- Replace the drain plug.
- Use a funnel to add the recommended Kohler engine oil based on your temperature conditions.
- Check the oil level using the dipstick and adjust as needed.
Step 5: Run and Recheck
Start the engine and let it run for a minute. Turn it off, wait a few moments, and check the oil level again. Add more oil if necessary.

FAQs
What oil do I use in my Kohler engine?
The best oil for your Kohler engine depends on the temperature and operating conditions. Below is a general guideline:
- Above 50°F (10°C): Use SAE 30 (conventional) for best performance.
- 0°F to 100°F (-18°C to 38°C): Use 10W-30 for a wider temperature range.
- Below 0°F (-18°C): Use 5W-30 synthetic oil for cold-weather operations.
For heavy-duty or commercial applications, 15W-40 or 20W-50 may be used, depending on the load and conditions.
Always check your engine manual for specific recommendations.
2. Should I use synthetic oil in a Kohler engine?
Yes, Kohler allows and recommends synthetic oil, especially in extreme temperatures. Full synthetic oils like 5W-30 or 10W-30 provide:
- Better cold-start performance
- Enhanced engine protection and lubrication
- Improved fuel efficiency
- Longer oil change intervals
However, if switching from conventional to synthetic oil, always follow the manufacturer’s guidelines and perform regular oil changes.
