Having claimed top spot last weekend with a 2-1 victory over Ratchaburi, the Thunder Castle had no such problems once again at the Nongprue Stadium.
Philippines international Javier Patino fired them ahead eight minutes before the break with his ninth goal of the campaign, before adding a second in the 70th minute after racing down the right and unleashing a cracking effort into the top corner.
Four minutes later, Carmelo Gonzalez tapped home his side's third from eight yards to cap off a fine outing for the league leaders.
The result also allowed Buriram to extend their lead at the top of the table to four points after second-placed Muangthong United fell to a 1-0 defeat at Bangkok Glass.
Plenty was expected from the defending champions given it was the first game since ex-Thailand boss Winfried Schafer took charge but he was unable to inspire his new charges, who ultimately succumbed to Piyachart Tamaphan's 60th-minute winner.
Elsewhere, Bangkok United made it two wins from two after beating Songkhla United 3-1 at the Thai-Japanese Stadium.
Thailand international Sompong Soleb opened the scoring for the hosts in the 14th minute and it was 2-0 six minutes later when Cameroonian striker Paul Ekollo found the back of the net.
Ekollo then netted his second of the game in injury-time to wrap up the three points for his side, although Songkhla did manage a consolation shortly after through a Aron da Silva effort.
In Sunday's final game, Ratchaburi were held to a 0-0 draw at home to Chiangrai United.
On Saturday, Chonburi maintained their grip on third place with a hard-fought 1-0 win over Police United; veteran striker Pipob On-mo scoring the only goal of the game in the 64th minute.
BEC Tero Sasana extended their unbeaten streak to nine matches but had to settle for a 1-1 draw at home to Osotspa Saraburi.
Japanese midfielder Sho Shimoji had put the Fire Dragons ahead on the stroke of halftime, but they ultimately had to settle for a share of the spoils after the visitors equalised through a strike from Chananan Pombuppha; his third in as many outings.
High-flying Suphanburi got back to winning ways with a 2-0 triumph over Chainat at the Suphanburi Municipality Stadium, a week after their run of three victories in a row was halted by a 0-0 draw against Bangkok Glass.
Suphanburi took the lead in the seventh minute when star striker Wuttichai Tathong struck his ninth league goal of the year, but they were unable to make sure of the three points until the 87th minute when Christian Castillo netted to kill off any hopes of a opposition fightback.
Finally, goals from Danny Invincibile and Monkol Tossagri either side of the break handed Army United a 2-0 win over Samut Songkhram at the Thai Army Sports Stadium.
