Loeb is 12.2 back in fourth spot, with Ogier down by 28.7.
The Rally France is one of the hardest tests of the season and combines wide and narrow roads with sections through the forest and a hilly climb to the village of Laitre.
Conditions in the morning were slippery but the roads dried out and Loeb dominated early.
"It was damp in places, tricky and difficult, so I tried to keep the temperature in my tires and be careful in muddy places," the Frenchman said.
He finished ahead of Sordo on the second stage, and then Neuville on stages 3 and 4.
Ogier struggled to keep up with the pace and only placed in the top four twice all day. Heading into the day's last special, Neuville led Loeb by 2.6 seconds and Sordo by 3.7, with a despondent Ogier lagging 24.7 seconds back in fifth.
"We didn't make the right choice of tires in the afternoon, when the roads were dry," Ogier said. "There are days like that."
There are seven stages on Saturday and a further six on Sunday.
"The weather was very difficult and I lost a lot of time in the afternoon," Loeb said. "The weather looks like it will be the same tomorrow. It's a shame, but that's the way it goes."
