McLaren has been forced to call an early halt to its running on the penultimate day of pre-season testing in Barcelona.
The team made an apparent breakthrough on day two, as Jenson Button completed 101 laps at the wheel of the Honda-powered MP4-30, but Kevin Magnussen just managed just 39 laps on Saturday before encountering an oil leak.
Despite the early stoppage, Magnussen was pleased with his first day at the wheel of the MP4-30 this year.
Jenson Button will drive the McLaren on Sunday, as pre-season testing concludes at the Circuit de Catalunya.
