Tallow which is made from animal fat, basically can be an ingredient for biodiesel. There is are many things to factor for biodiesel applications. CAT has a fuel specification guide which should be consulted.
Some things to consider:
1- what is your application? New engine, older engine, emissions requirements, etc...stationary, truck, tractor, ???
2- are long periods of fuel storage required? (Biodiesel is known to have storage issues as organic compounds will grow in the fuel.)
3- What is the blend of the biodiesel and does it meet the CAT fuel specs? (B100, thermodynamic energy, etc...)
4- Fuel treatment costs
5- what is your need for biodiesel? cost vs conventional fuel....? just experimenting??
Theres are many other factors to consider. I would contact your CAT dealer and have them run through the scenarios for your area and application...
