Ideal for intermittent use

✅ Diesel Generator Advantages:

Better fuel efficiency

Longer lifespan

Lower operating costs

Better for continuous operation

Detailed Comparison

1. Fuel & Operating Costs

Gasoline Generators:

Higher fuel prices

Higher fuel consumption

Best for short-term use

Diesel Generators:

More economical fuel

15-20% higher thermal efficiency

More cost-effective for long-term use

2. Performance Characteristics

Starting Performance

Gasoline Generators: works at -20°C

Diesel Generators: needs preheating below 0°C

Power Output

Gasoline Generators: 1-12kW range

Diesel Generators: 5-50kW+ range

Maintenance & Lifespan

Gasoline Generators: oil change every 100h; 1,500-3,000h lifespan; simple maintenance

Diesel Generators: oil change every 500h; 5,000-10,000hr lifespan; requires professional maintenance

Buying Guide-Choose by Application
