Bio Fuel Refining Guide
With the Biofuel refiner you can convert raw food and honey into fuel for your engines.
The quantity of raw food needed to create 1 biofuel depends on which type of food you use.
So i decided to test all raw foods and share the results.

Since the potato has the lowest efficiency all foods, all other foods will have their efficiency measured in potatoes.
It is important to know that a single unit of biofuel requires 20 potatoes worth of food (plus 1 unit of honey) and the refiner can store up to 40 potatoes worth of raw food.
Here is the list from best to worst.

Potato equivalent
********************
mama bear head = 40
puffer head = 30
shark head = 20
warthog head = 20
screecher head = 20
bear head = 20
sharkmeat = 15
red berries = 12.5
milk = 10
catfish = 10
salmon = 10
melon = 8
drumstick = 8
raw meat = 7
tilapia = 6.5
mackerel = 6.5
egg = 6
mango = 4
pineapple = 4
coconut = 4
pomfret = 4
herring = 4
raw beet = 1

2 raw foods are not compatible/bugged at the time of writing:
Mushrooms show prompt to add but nothing happens when pressing E.
Silver algae is not treated as compatible raw food (this one could be by design rather than
a bug).

Hope this info is of use.

for finishing the story line in chapter 2 I used to medium crop plots with melons. I prefer them as a source because they grow relatively quickly and do give a good fill. Going with the milk/egg variant is kinda bothersome in mid-game because I was way too lazy to water the fields, set up the irrigation or even collect the milk. Melons on the other hand are easy to handle.

Thanks for your guide tho. I didn't even know meat and fish could be used. Now I know where to put all these heads and stuff

Mushrooms are very useful. I think you should check it soon, as it is the most effective food item that i will use (including most heads)

anyone know how efficient banana's are I use banana's and am wondering if there are easier methods because they work pretty wel

I have about 8000 shark heads so this is gonna be good

Egg's are 1000% easiest to do, 7 of them fills a biofuel converter on top egg's also being a good source of emergency food while powering the generator to keep animals fed.

I found most efficient to just farm Eggs. With 6 birds and 10 beehives it´s almost unlimited biofuel.

Never realised that the heads of animals give you bio material, so thanks for that. I normally just use potatoes and they are pretty quick to grow, but maybe I can cut down on manual labour growing something else!

Hi! Thanks for making this guide :) can you add strawberries and bananas? also how do you measure this? thankss!
