Joe Hartley's first-half hat-trick of tries helped Oxford to a 48-7 win at Wheatley in the BB&O Premier Division.
Wheatley started well in the blustery conditions with Russell Neal going over in the corner and young fly half Sam Butler converting.
Wing Hartley bagged his first try after gathering a chip ahead before Joe McAnearney burst away from the back of a lineout and Hartley converted.
A charge down saw centre Dominic Clarke run in try No 3, while Hartley cruised over unopposed for his second and converted both.
Hartley also converted his hat-trick try, created by fly half Phil Longuet-Higgins, to give Oxford a 33-7 half-time lead.
Wing Mario Da Silva, Longuet-Higgins and flanker Rupert Martin all crossed after the break.
Gosford All Blacks fell to a 39-7 defeat at Broadmoor Staff despite a promising start.
Centre Ben Yates opened the scoring for Broadmoor, with Adam Redding converting his try.
Redding slotted a penalty after Murray Stewart had been sin-binned and converted the next try from Chris Bennett.
Bennett and Yates were next on target with Redding converting the former.
Gosford's Martin McNally, a replacement at No 8 for the injured Liam Beesley, immediately galvanised the pack.
But his influence was short-lived as he and a Broadmoor player were red-carded for a mild skirmish on 50 minutes!
Broadmoor managed another Bennett try, converted by Redding, who added a penalty.
Gosford's consolation try came from skipper Dan Hughes, converted by Elliott Newell.
