Quick Answer
Yes, the type of oil matters for long-term storage as it affects the oil's viscosity and degradation rate, potentially leading to engine damage or reduced performance when used.
Choosing the Right Oil for Long-Term Storage
When storing a generator for an extended period, the type of oil used is crucial for maintaining its condition and ensuring a smooth start-up when needed. It is essential to use a high-quality oil that is designed for long-term storage, such as a synthetic or synthetic blend. These oils are more resistant to oxidation and degradation, which can occur due to exposure to heat, light, and air.
Storage Oil Specifications
Look for oils with a high viscosity index (VI) and a low pour point to ensure they remain fluid and lubricate the engine properly even in cold temperatures. A good starting point is to use an oil with a VI of 120 or higher and a pour point below -20°C (-4°F). Some examples of suitable oils include 10W-30, 5W-30, and 0W-30 synthetic blends. It is also essential to check the oil’s shelf life and ensure it is not expired or near its expiration date.
Proper Storage and Handling
Proper storage and handling of the generator and oil are also critical for long-term storage. Store the generator in a well-ventilated area, away from direct sunlight and heat sources. Keep the oil level at the recommended minimum to prevent degradation and contamination. If the generator will be stored for an extended period, it is recommended to change the oil every 6-12 months to maintain its quality and prevent degradation.
