Lewis Hamilton: I pushed for win in Mexico
The Brit finished runner-up to Mercedes team-mate Nico Rosberg on Sunday, seeing the German return to second in the drivers' championship.
Hamilton said he was still trying to win at the Autodromo Hermanos Rodriguez, where he finished almost two seconds behind.
"I was pushing the whole way it's just that you can't follow," he told a news conference.
"Soon as I'd get four, five, a few car lengths behind, just to lose the aero, and he had perfect aero so it was impossible to get close enough but I had good pace.
"But as soon as you get closer and closer and closer you lose all your downforce."
Hamilton, whose lead atop the championship is 73 points, said he was happy with how the track played.
The 30-year-old had no problems with his brakes or engine temperatures.
"It was fairly easy, it was fairly easy," Hamilton said.
"There was not really much degradation on tyres, if any, and the brakes, yeah, you just have to do a little bit of lifting and coasting but it's no different to anywhere else."
