Do cars running on coal feel wrong? This mod replaces solid vehicle fuels with liquid fuel barrels.

• Disables solid fuels for supported vehicles
• Supports cars and tanks, AAI Vehicles: Ironclad, Hovercrafts, and ships from the Cargo Ships ecosystem
• Uses fuel categories derived from liquid fuel barrels such as light oil, petroleum gas, heavy oil, and optionally rocket fuel
• Small boats and larger ships can use different liquid fuel sets
• Startup settings let you define allowed fuel items for each supported vehicle family
• The crash site contains one barrel of light oil so your first car can be fueled immediately

Barrel production makes a bit more sense with this mod.

Recommended mods:

• No Vehicle Pickup or Vehicles retain fuel when picked up
• Liquid Rocket Fuel - adds rocket fuel barrels for vehicles
• Barrel recipes 2.0
• Barrel Fluid Icons
• Barreling Group
