The Most Efficient Fuel in Last Day on Earth: Survival
In Last Day on Earth: Survival, there are five types of fuel you can use to power Campfires, Melting Furnaces, and Refined Melting Furnaces: Pine Logs, Pine Planks, Oak Logs, Oak Planks, and Charcoal.
These fuels are essential for cooking food and processing metals into metal bars.
But you might be wondering: Which fuel is the most efficient?
To find out, I conducted an experiment to compare the burn times of each fuel type. Here are the results…
The Most Efficient Fuel for Campfires and Furnaces
The time difference in the table below is due to differences in fuel consumption: furnaces burn fuel faster than campfires.
| Fuel | Campfire | Furnace |
|---|---|---|
| Pine Log | 2 Minutes | 1 Minute 20 sec |
| Pine Plank | 3 Minutes | 2 Minutes |
| Oak Log | 2 Minutes | 1 Minute 20 sec |
| Oak Plank | 3 Minutes | 2 Minutes |
| Charcoal | 6 Minutes 40 sec | 5 Minutes 20 sec |
As you can see, Pine Log, Oak Log, Pine Plank, and Oak Plank burn much faster than Charcoal.
Therefore, Charcoal is the most efficient fuel in terms of burning time, followed by Pine Plank and Oak Plank.
However, Oak Log and Oak Plank are harder to obtain than Pine Log, so I generally don’t recommend using them unless necessary.
Processing Time for Planks and Charcoal
Pine Planks and Charcoal are efficient, but they require additional processing. Converting 1 Pine Log into 1 Pine Plank through a Woodworking Bench takes 4 minutes.
Charcoal production also requires 4 minutes plus additional fuel. For example, making 20 Charcoal from 10 Pine Planks can take around 40 minutes.
So if you need fuel quickly for cooking food or smelting Iron Bars, Pine Log is your best choice.
That said, when you have the time, I still suggest turning Pine Logs into Pine Planks or Charcoal for better efficiency.
My Strategy for Making Charcoal
Here’s how I personally get the most Charcoal:
- Always stock up on Pine Logs.
- Place 20 Pine Logs onto two Woodworking Benches.
- After getting Pine Planks, place 10 of them onto a Campfire with 8 or more Pine Planks as fuel.
- Once you get 6 Charcoal, replace the fuel with the 6 Charcoal.
- Place 10 Pine Planks onto the Campfire to produce 20 Charcoal. Use the 6 Charcoal from the previous batch as fuel.
- Store 14 Charcoal and use 6 Charcoal to repeat the process from step 5.
That’s my recommended approach. Keep in mind that fuel resources and efficiency may change with future updates from Kefir!.
