Australian Mark Webber admits he has been frustrated by Red Bull Racing's reliability problems this season.
The Austrian-owned squad's year has been blighted by reliability issues, with eight retirements through mechanical issues in 12 races so far.
Webber has retired five times this year, including his exit from the Turkish Grand Prix two weeks ago, when he was the only driver who failed to cross the finish line.
"The whole team is getting frustrated with it (reliability problems) but all we can do is keep trying to press on and learn from the errors that we've made," Webber told a news conference in Italy.
"It's not as painful when you're in good point-scoring positions, because I've had plenty of those as the season has gone by. But in Turkey we were not quick enough to get any points anyway, so it saved me the hard work of driving around for nothing."
The Australian, who has scored Red Bull's only podium finish of the season, says he has been happy with his own performance throughout the year.
Webber admits, however, that it's not easy to stay fully motivated when not fighting for point-scoring positions.
"I'm happy with how I have driven this year. That's been enjoyable to an extent," he said. "But you can only drive around in that sort of position for so long until you're not really enjoying it as much and your motivation to keep pushing for P11, P10, so, yeah, it's just so competitive.
"Renault, Toyota, it doesn't mater who, it's hard to get into the points. And there's only one thing you can do about it, and that's make a quicker car and be consistent with yourself each weekend to try to do the best job possible. If the car breaks, it's not my job to try to fix those problems.
"I think we should finish off more strongly, reliability-wise. Which wouldn't be hard. We did some tests here to try and simulate why my failure happened in Turkey, and it didn't happen again, so that was that reason out of the window. So we're getting more information."
