Red Bull team principal Christian Horner has expressed his doubts about the re-introduction of refuelling to Formula 1, saying that people have "short memories".
Refuelling was used in F1 between 1994 and 2009 but was abandoned due to safety concerns and financial factors which in turn had made races much more of a tactical battle.
Horner believes that if it will not improve racing, then the idea should be scrapped.
"Perhaps a bit more time to consider it might show it was not the best thing. If it's going to create better racing, I am all for it. But at the moment I can't see that it will," Horner told BBC Sport.
"We need to be a bit careful. People have short memories. We got rid of refuelling for good reason - not just cost but because the races became more tactical between the teams.
"You are going to slow the pit stops down, fuel according to what competitors do, the races could become more stagnant."
F1's governing body announced last week that refuelling will make a return to the sport in 2017.
