Pour point of fuel oil is the

Temperature at which it solidifies or congeals

Indicated by 90% distillation temperature i.e., when 90% of sample oil has distilled off

It catches fire without external aid

Minimum temperature to which oil is heated in order to give off inflammable vapours in sufficient quantity to ignite momentarily when brought in contact with a flame
