Marussia believes it will have to fight to hang on to 10th place in the constructors' championship following its best-ever finish in the Singapore Grand Prix.
Timo Glock's 12th place at the Marina Bay circuit was enough to lift the outfit ahead of Caterham.
Marussia is now on for a potential leap in income if it can keep tenth until the end of the season. However, the team knows it can take nothing for granted with six races remaining.
President and sporting director Graeme Lowdon told AUTOSPORT: "We are well aware, like everyone else, that we still have to fight at every race from now until the end of the season.
"There can easily be carnage somewhere and it would be desperately disappointing if we are not at the front of the battle if that happens.
"None of the new teams have finished higher than 12th [since joining the grid in 2010], so statistically this is a mega result. But we cannot sit back and think that is it. We have to keep pushing."
Marussia's step forward in form over recent races is the result of an upgrade package that was introduced at the Belgian Grand Prix.
And although historically finishing top ten in the standings has had significant commercial benefits, Lowdon says it is too early to judge what lift in income his outfit could expect to get if it holds onto the position.
"Because there is a new Concorde [Agreement] period, it is unclear," he said when asked if there was any idea of how much his team could stand to earn from finishing 10th.
"There are a lot of strange things in F1, but you would hope that finishing tenth is better [financially] than finishing 12th.
"I think the key focus for us is to finish as high as we can and hopefully everything else will come out in the wash.
"Historically there has been a massively large difference, so we should not underestimate the potential value."
