Woods, who plays host at the Sherwood Country Club, took full advantage of the birdie opportunities that came his way to tie his own course record and move to 11 under par overall.
Woods' day-two efforts were a far cry from his opening round, which began with a bogey on the first before he made gains at five and 11. Twenty-four hours on Woods kicked off with a birdie at the first, repeating the trick on the second hole before further gains at five, seven and eight.
The birdies continued after the turn as he picked up shots at 10, 11, 13, 14 and 16, before a pair of pars finished off a blemish-free round.
Johnson looked in similarly sweet form as he birdied three of the first five holes, but he parred the next 12 there before picking up an extra stroke at the 18th to put him clear in second.
Matt Kuchar was a shot behind on eight under, while defending champion McDowell moved into fourth place, improving vastly on his level-par first round by going five under.
While four bogeys hampered him on Thursday, he was blemish-free second time around with five birdies moving him up the field, one clear of Bubba Watson.
There was worse news still for McIlroy whose five-over 77 left him joint 16th in the 18-strong field.
The Northern Irishman struggled all day, with a double bogey at the fourth and further dropped shots at the eighth, 12th, 13th and 14th, but the low point came with a quadruple bogey at the 16th.
