Conservative MP Robert Halfon is set to raise the issue of the UK's high fuel costs in Westminster Hall as part of a parliamentary debate.
The MP claims despite a recent fall in oil prices, fuel companies have not reduced the prices they charge.
Mr Halfon said the cost of running a vehicle is the "number one" issue in his constituency and across the nation as a whole.
With motorists facing rising fuel and car insurance costs, the issues resonates nationwide.
Speaking before the debate, Mr Halfon said: "Motorists and businesses are genuinely suffering, and the high fuel price is an obstacle to bringing jobs back and getting our economy moving again.
"The oil price is falling internationally but hard-pressed British motorists, businesses and road freight companies are still paying inflated prices at the pump. That's why I have written to all the major energy companies, to ask if they will lower their prices across the country."
The FairFuelUK campaign is also backing the debate, which will be attended by motoring expert and TV presenter Quentin Willson, who also seeks a probe into the matter.
He said: "Who's making the money and why aren't these oil price falls being passed on? We need an inquiry into this and we need it now."
