Honda G23 Engine: Specs, Configuration, Oil & Service Intervals

Honda G23 Engine Specs

The Honda G23 engine is a four-stroke, gasoline-powered engine that is commonly used in a variety of applications, including lawn mowers, generators, and small construction equipment. This reliable and efficient engine is known for its durability and performance. In this article, we will explore the engine configuration, engine oil specs, and service intervals for the Honda G23 engine.

Engine Configuration

The Honda G23 engine features a single-cylinder design with a displacement of 230 cubic centimeters (cc). It is an overhead valve (OHV) engine, which means that the valves are located in the cylinder head, allowing for better airflow and improved combustion efficiency. The engine is air-cooled, meaning it relies on air circulation to dissipate heat and maintain optimal operating temperatures.

The G23 engine is equipped with a recoil starter, which allows for easy manual starting. It has a bore and stroke of 70 mm x 58 mm, and a compression ratio of 8.5:1. The engine is designed to run on regular unleaded gasoline with a minimum octane rating of 87.

Engine Oil Specs & Service Intervals

Proper maintenance and regular oil changes are essential for the longevity and performance of the Honda G23 engine. Here are the engine oil specifications and recommended service intervals:

• Engine Oil Type: The Honda G23 engine requires a high-quality, four-stroke engine oil. It is recommended to use a SAE 10W-30 oil for general operating conditions. However, for extreme temperatures, such as very hot or cold environments, a different viscosity oil may be required. Consult the engine manual or contact a Honda dealer for specific recommendations.
• Oil Capacity: The engine has an oil capacity of approximately 0.6 liters (0.63 quarts). It is important not to overfill or underfill the engine with oil, as it can lead to performance issues or engine damage.
• Oil Change Interval: The recommended oil change interval for the Honda G23 engine is every 50 hours of operation or once a season, whichever comes first. However, if the engine is operated in severe conditions, such as dusty or dirty environments, more frequent oil changes may be necessary.
• Oil Change Procedure: To change the engine oil, follow these steps:
  1. Run the engine for a few minutes to warm up the oil, as warm oil flows more easily.
  2. Turn off the engine and let it cool down for a few minutes.
  3. Locate the oil drain plug underneath the engine.
  4. Place a drain pan underneath the engine to catch the old oil.
  5. Remove the drain plug and allow the oil to completely drain into the pan.
  6. Once all the oil has drained, reinstall the drain plug and tighten it securely.
  7. Refill the engine with the recommended amount and type of oil.
  8. Check the oil level using the dipstick and add more oil if necessary.
  9. Dispose of the old oil properly by taking it to a recycling center or an authorized oil collection facility.

By following the recommended engine oil specifications and service intervals, you can ensure that your Honda G23 engine operates smoothly and efficiently for years to come. Regular maintenance and proper care will help maximize the engine’s performance and reliability.
