How Do I Start My Generator in Cold Temperatures?

Starting a generator in cold weather may require a few additional steps to ensure proper engine performance.

For operation in below-freezing temperatures, we recommend using 5W-30 full synthetic engine oil. Synthetic oil flows more easily in cold conditions and helps the engine start more reliably.

Tips for Cold Weather Starting

Use the Proper Engine Oil

Use 5W-30 full synthetic oil when operating the generator in freezing temperatures. This helps improve lubrication and reduces resistance during engine startup.

Allow the Generator to Warm Up

Once started, allow the generator to run for several minutes without load so the engine can warm up before connecting electrical devices.

Consider Fuel Additives for Gasoline

In extremely cold climates, using a fuel additive designed for cold weather may help improve gasoline performance and prevent fuel issues.

Use a Propane Tank Warmer (If Running on Propane)

If using propane in very cold temperatures, the propane tank pressure can drop due to cold weather. In these situations, a propane tank warmer may help maintain proper fuel pressure.

Important Cold Weather Tip

⚠ Cold temperatures can affect fuel pressure, battery performance, and engine oil viscosity. Using the correct oil and fuel setup will help ensure reliable starting.

Common Questions

Why is my generator harder to start in cold weather?

Cold temperatures can cause:

• Thicker engine oil

• Reduced battery performance

• Lower propane tank pressure

These factors can make the engine harder to start.

Should I store my generator indoors during winter?

The generator should be stored in a cool, dry location, but it should always be operated outdoors due to carbon monoxide safety concerns.
