Key Considerations for Choosing Between LPG and Fuel Generators

04/04/2025 / Generators

Choosing between a LPG and fuel generator depends on various factors, including fuel efficiency, cost, storage, and environmental impact. LPG generators offer a longer shelf life, quieter operation, and lower emissions, making them ideal for home backup and long-term use. However, they come with higher upfront costs and lower fuel efficiency. On the other hand, fuel generators are initially more energy-efficient, portable, and cost-effective but require careful fuel storage and frequent maintenance. Understanding the key differences in efficiency, cost, and usability ensures an informed decision based on individual power needs.

GT4000Gi - LPG/Petrol
I bought the GT4000 as part of my emergency preparedness/civil defence/power outage kit because these days, the price of the food in your deep freezers is in the thousands of dollars. Price of unit reasonable compared to other brands. Prompt delivery. Great customer support from Proline. Pros of unit itself: Quiet running on LPG. Has carry handle/wheels, so suitable for solo operators. Larger fuel tank maximises run time if using petrol. LPG option great for emergency situations when petrol becomes unavailable. Easy start. Operation of unit is intuitive and easy. Comes with everything you need, e.g., long-life fuel additive, LPG regulator kit, dust cover. Has 3 start methods (great redundancy): recoil start as well as remote and electronic button start. Good warranty period, same as leading brands. Cons: Instruction manual somewhat unclear. Unit could come with smart trickle charger thrown in since many users won't be running unit all day every day. Bulky, but probably no more so than other brands. Overall: Still haven't tested it extensively in emergency, but my brief test went smoothly. I think the GT4000 is a very good unit and will keep me out of trouble as long as the house stays standing.

I bought this to use as a backup generator and so far it has been excellent. I've had it for one month. I bought the LPG version so that I don’t have the hassle of petrol going bad in storage. I do not have any petrol powered equipment, so I would’ve been storing petrol just to power a backup generator. That said, I like that it can operate on petrol too because it’s nice to have options in an emergency situation. With one press of the wireless remote it starts instantly on both petrol and LPG. I tested the output with a 3.5kw load and it had no problems. It also started a 1hp induction motor easily (bench grinder). I appreciate the 4 year domestic warranty and 10 year spare parts availability guarantee! This generator will be rarely used in my application and I would be annoyed if it broke and I couldn’t repair it after only a few years. The only downside is that it is not cheap. Being quieter and dual fuel comes at a price. The generator is basically identical to the Westinghouse iGen4500DF that is sold overseas, so you can look that up and see lots of reviews. Shout out to Tim for the excellent service.
