Crude oil is a key ingredient in petrol and diesel, meaning higher oil prices could eventually drive up prices at the pumps.
The AA motoring group says that over the next few weeks fuel costs could return to where they were at the start of the year.
That would be a change to the general trajectory of fuel prices, which have been falling on UK forecourts over the past few weeks.
Further rises will depend on the magnitude and duration of the conflict, the AA said.
Currently, the average price for petrol is 133.2p a litre and 142.7p for diesel, according to AA data.
Simon Williams, from rival motoring group the RAC, said: “The oil price would have to rise significantly and stay that way for some time to have a dramatic effect.
“If oil were to climb to and stay at the $80 a barrel mark, then drivers could expect to pay an average of 136p for petrol.
“At $90, we’d be looking at over 140p a litre and $100 would take us nearer to 150p, but it’s all too soon to know.”
