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

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

It catches fire without external aid
