Culter produced an excellent display at Ian Mair Park to hit Dyce for six and stay top of the Superleague.
The visitors got off to the perfect start after only nine minutes when Andrew Sim played a one-two with Greig and left two defenders in his wake before curling a terrific shot into the top corner.
Duffy was quick off his line to deny Steve Bartlet but, seconds later, the Culter ‘keeper totally misjudged a deep cross and was glad to see Kelly kick Neish’s goal-bound effort off the line.
Culter doubled their lead in the 29th minute. McAllister found space on the right and his perfect pass found Scott McArthur who slotted home with ease.
McAllister was through with only Buchanan to beat in the home goal but his right-foot shot spun past the post.
McAllister then latched on to Leith’s long pass but Buchanan saved the striker’s shot. Brown’s brilliant block denied Reid before McBain replaced the injured Taylor on the 41st minute.
In first half stoppage time Robertson’s long ball was flicked on by McBain, the ball was picked up by Davie Greig whose stinging 20-yard shot could only be palmed into the net by Buchanan.
Dyce were quick off the blocks and Mark Bartlet’s header flew just wide.
Steve Bartlet then had Duffy at full stretch as he turned the ball away for a corner.
From the resultant kick, he then produced a great reflex save to once again deny Bartlet.
Brown robbed Neish of the ball and found McBain, whose first-time cross was turned into the net from close range by Jamie McAllister in the 57th minute.
Two minutes later, McBain flicked the ball wide to Greig whose cross found McAllister and he rammed the ball into the net for 5-0.
In the 69th minute,, Youngson’s pass over the home defence found George McBain whose run also produced the perfect finish when he scooped the ball over the home keeper.
