27 HP Kohler Engine Oil Capacity(For ALL Series)

One of the most important aspects of Kohler engine maintenance is keeping the oil level correct and changing it at the right intervals. In this guide, we’ll cover the oil capacity of the 27 HP Kohler engine, the best oil types to use, and some essential maintenance tips.

27 HP Kohler Engine Oil Capacity

Most 27 HP Kohler engines, such as those in the Command PRO and Courage series, have an oil capacity of about 2.0 to 2.1 quarts (1.9 to 2.0 liters) when changing the oil filter and slightly less, around 1.8 to 1.9 quarts, without a filter change.

Kohler 27 HP Engine Series	Oil Capacity (with filter)	Oil Capacity (without filter)
Command PRO CH752	2.0 quarts (1.9 liters)	1.8 quarts (1.7 liters)
Command PRO ECH749	2.1 quarts (2.0 liters)	1.9 quarts (1.8 liters)
Command CV742	2.0 quarts (1.9 liters)	1.8 quarts (1.7 liters)
Courage SV840	2.0 quarts (1.9 liters)	1.8 quarts (1.7 liters)
7000 Series KT745	2.0 quarts (1.9 liters)	1.8 quarts (1.7 liters)

Kohler recommends SAE 10W-30 oil for most conditions, with 5W-20 or 5W-30 for temperatures below 32°F (0°C) and SAE 30 for consistently hot climates above 80°F (27°C).

Recommended Oil for a 27 HP Kohler Engine

Kohler recommends SAE 10W-30 oil for most operating conditions. However, the right oil weight may vary depending on the temperature in your area:

Above 32°F (0°C): SAE 10W-30
Below 32°F (0°C): SAE 5W-20 or 5W-30
For hot climates above 80°F (27°C): SAE 30

For best results, choose API Service Class SJ or higher, and look for oil that’s specifically formulated for small engines. While automotive oils can work, small engine oils often have additives designed to protect against corrosion and handle the higher operating speeds of mower engines.

Why Oil Capacity Matters

Using the correct amount of oil is not just a technical recommendation—it’s a necessity for the health of your engine.

Too Little Oil: This leads to inadequate lubrication, increased friction, and higher operating temperatures, which can cause premature engine wear or even complete failure.
Too Much Oil: Overfilling can cause foaming, reduced lubrication, and excessive pressure that may damage seals and gaskets.

Keeping oil at the proper level ensures that moving parts are adequately lubricated, heat is dissipated efficiently, and contaminants are suspended until the next oil change.

How to Check Oil Level on a 27 HP Kohler Engine

Checking the oil is a quick maintenance task that can save you from costly repairs. Here’s how:

Park on a Level Surface: Ensure the mower is on flat ground to get an accurate reading.
Turn Off the Engine: Let it cool for a few minutes before checking.
Locate the Dipstick: Usually found on the side of the engine near the oil fill cap.
Wipe and Reinsert: Remove the dipstick, wipe it clean, insert it fully, then remove again to check the oil level.
Check Against Marks: The oil should be between the “Full” and “Add” marks.

Oil Change Procedure for a 27 HP Kohler Engine

Changing the oil in your Kohler engine is straightforward. Here’s a step-by-step guide:

Tools and Materials Needed:

2 quarts of recommended oil
New oil filter (if changing)
Oil drain pan
Funnel
Clean rag

Steps:

Warm Up the Engine: Run it for 2–3 minutes to make the oil flow more easily.
Drain the Oil: Locate the drain plug (usually under the engine), remove it, and let the oil flow into the pan.
Replace the Oil Filter: If changing, remove the old filter, lubricate the gasket on the new one, and screw it into place.
Refill with Fresh Oil: Using a funnel, add the recommended amount of oil slowly.
Check the Level: Run the engine briefly, turn it off, let it settle, and recheck the oil level.
Dispose of Old Oil Properly: Take used oil to a recycling facility.

Oil Change Intervals

Kohler generally recommends:

First oil change: After the first 5 hours of use (break-in period).
Regular changes: Every 50 hours of operation or annually, whichever comes first.
More frequent changes: If operating in dusty, dirty, or extremely hot conditions.

Tips for Longer Engine Life

Always Use Fresh Oil: Avoid using oil that’s been sitting open for years.
Replace Air Filter Regularly: Dirty air filters allow dust into the engine, contaminating oil.
Check for Leaks: Oil spots under your mower could indicate seal or gasket issues.
Keep Cooling Fins Clean: Overheating can break down oil faster.
Use OEM Parts: Kohler filters and recommended oils ensure compatibility and performance.
