Jamie Whincup has once again run out of fuel at Mount Panorama - but this time it was planned, as the team determines the Red Bull Holden Commodore's fuel consumption.
Whincup finished 12th in the first practice session of the Supercheap Auto Bathurst 1000 and is looking to redeem himself after running out of fuel on the last lap and succumbing to a charging Chaz Mostert.
"This one was a bit more planned than the last one," Whincup said.
"We obviously do a fair bit of fuel stuff, as you always do at Bathurst - and we ran out of fuel and had to be pushed up pit lane."
Whincup said the team wanted to be 100 per cent sure of the fuel numbers, as economy is always a huge factor in the endurance races.
The cars have a new gear ratio this weekend, which could effect consumption.
The six-time and defending champ played down the team's tactics in practice and the focus on fuel numbers.
"No more than usual to be honest," he said.
"It's [about] making sure that if we need to conserve right until the end we can, because we have our fuel numbers spot on."
