Neal soon took his former team-mate come the end of lap four in the same move that first saw him past Plato. Unlike the SEAT, Thompson was unable to offer a riposte, and had far bigger concerns as he clipped a kerb and got luridly sideways.
The front was still a battle between Muller and Reid, with Frenchman Muller placing his car perfectly to make any clean passing move from Reid not quite come off, no matter where or how the Scotsman might make it.
Behind the duo Colin Turkington had dropped back, and was soon to be reeled in by the hard-charging Matt Neal with what was to be the race's other one-on-one battle.
Race two sees the top ten reversed grid so attention was focused on tenth as ever in the first race of the day. For much of the race this place was occupied by Shaun Watson-Smith, but Jason Plato's thoughts soon changed to this position after he had been taken by Matt Neal.
Slowing for a cigarette and allowing his competitors through with good grace, Plato masterfully got himself into ninth, meaning a second place start for the afternoon's first race, and the SEAT should be a very strong contender here.
Along side Plato and in pole for race two sits Michael Bentwood who gained the tenth place after some of the usual fraught movement for position in the midfield in the dying laps of the 14 lap BTCC encounter.
During this Oulton park winner Dan Eaves found himself in the tyre wall from eleventh place, and long-term tenth position holder Shaun Watson-Smith lost out to finish in twelfth.
As the cars crossed the line it was Muller who had resisted the Anthony Reid onslaught for the entire race to take the chequered flag by a mere 0.227secs. It was then a 6 second gap to Colin Turkington who was afforded a little breathing space from Matt Neal after a solid resistance for the latter half of the race.
The race win was Muller's fourth win of the year and means he equals James Thompson's 29 wins. For the next race at the hard to pass track Muller will start in tenth on the grid. Things could get interesting.
