Diesel drivers are still paying more than they should be despite fuel prices falling for the fifth straight month in March, according to the RAC.
The motoring experts, who offer an online Fuel Watch service, have analysed data from last month and found that diesel motorists should be seeing "far bigger" cuts. Diesel has dropped to 162.94, saving drivers £15 a tank compared to November of last year.
They say that wholesale prices were very similar through the month and so diesel - costing 160.98p on average in Scotland by the end of March - should be priced closer to that of unladed fuel, which was 145.77p on average.
