Autogas is typically a mixture of propane and butane but can be all propane.
The chemical formulas for propane – C3H8 – and butane – C4H10 – are different. However,the formula for butane and isobutane are the same. Isobutane (i-butane) is an isomer of butane, so it has a different arrangement of its atoms.
