Maintain a balanced level of petroleum, heavy and light oils by switching different refinery methods and oil cracking
Two blueprints available in this book
- Base Refinery BP: only petroleum, heavy and light oil
- Additional Refinery BP: Base Refinery + sulphuric + lubricant manufacturing
NOTE:
There is a small bug that crude oil pumps are not working when storage tanks are empty or near empty (lower than 1%). To avoid this use a bypassed pipe to one set of oil refineries until tanks have more than 1% of oil in it.
