Kimi Raikkonen is reluctant to make any predictions about the upcoming Chinese GP after experiencing both highs and lows already this season.
While the 2007 World Champion's season got off to a winning start in Australia, Lotus were unable to keep up in Malaysia.
Raikkonen, who had a "tough" race in the wet, finished down in seventh place, which meant he dropped to second in the Drivers' standings.
The Finn trails Sebastian Vettel by nine points and isn't willing to say whether he can make up the deficit this weekend in China.
"It's always difficult to predict what will happen in the next race as we haven't been there yet with this car, and every car reacts differently to each circuit," he said.
"Unfortunately we didn't achieve any points there last year so we can only improve from that.
"I have been first, second and third in Shanghai in previous years so it would be nice to add to that list."
Lotus head into round three with various minor upgrades including tweaks to the front wing, rear wind end-plates and sidepod vanes.
"There's no reason why we shouldn't go well there," Raikkonen added. "We have some new parts for the E21 and the last upgrades we had seemed to help so it will be interesting to see what will happen if it doesn't rain."
