Mark Webber had few complaints about his running at Barcelona on Friday other than the "less enjoyable" part of putting mileage on old tyres.
After a wet start to proceedings on Friday morning, which saw Red Bull finish well off the pace on a drying track, the Bulls were back on form in the afternoon's session.
Almost immediately Webber and his team-mate Sebastian Vettel made a charge up on the timesheets on the hard Pirelli tyres and when everyone swapped to the mediums they put in a repeat performance.
Vettel finished at the top of the timesheets while Webber, who was third quickest, was just 0.083s down on the German.
"It looks reasonably tight," Webber said.
"We had a good time on fresh tyres and enjoyed it and then we go out and drive around and save tyres, the less enjoyable part of the job! But anyway that's what we've got to do.
"We couldn't have got much more out of it today in terms of info considering the first session was a bit scrappy for everybody because of the weather.
"But overall, a pretty good day for us. We'll find out on Sunday."
