The RAC urges motorists to consider filling up ahead of the coming week after warning that petrol and diesel prices are likely to increase. Both reports cite RAC policy chief Simon Williams, who links pump prices to movements in global oil markets. Williams says the prices drivers pay at the forecourt depend heavily on the global oil price, which has been rising following the end of a ceasefire. The articles describe the outlook as “pretty grim,” with expectations that further increases may occur during the week. While the sources differ slightly on the specific cutoff day mentioned—one advises drivers before Thursday and the other before Friday—they broadly agree on the message: rising global oil prices are filtering through to UK fuel costs and may lead to higher pump prices soon. No specific figures, locations, or confirmed price changes are provided in the excerpts, but both outlets frame the situation as a near-term risk for drivers facing higher petrol and diesel bills.
