Lewis Hamilton is unconcerned about engine issues that appear to have been creeping in at Mercedes, explaining that "it's not my job to worry about that stuff" during the remaining races of the season.
Hamilton was hit with a grid penalty at the Turkish Grand Prix after taking on a new engine and, despite recovering from 11th to fifth, he lost the World Championship lead to Red Bull rival Max Verstappen.
Speaking over the weekend, Mercedes boss Toto Wolff refused to rule out Hamilton needing a fifth engine to reach the end of the season, with six races still to go.
It comes after reports of Mercedes recently taking their entire stock of current power units back to Brixworth for extensive analysis, with claims that Valtteri Bottas has even lost a fresh engine from his pool.
Asked if he is concerned about Mercedes' engine situation, and potentially being forced to take another engine before the end of the season, Hamilton claimed that he is not giving much thought to the situation.
"I don't really give any energy to it," Hamilton told media, including RacingNews365.com.
"It's not my job to worry about that stuff, so I let the guys focus on that, worry about it.
"My engine is in good condition. My first engine, I think, did six races. We still have engine two, and I think engine three is still there.
"As far as I'm aware, hopefully I don't have to [use a fifth engine], but I can't predict what's up ahead."
Hamilton now trails Verstappen by six points in the standings, with the Dutchman coming home second at Istanbul Park, behind Bottas.
