“Retail gasoline prices across the country appear to have hit a plateau and that's not surprising given the mix of potentially upward and downward forces working simultaneously on crude oil prices," said Gregg Laskoski, senior petroleum analyst for GasBuddy.

"On one hand we have the news that OPEC issued over the weekend; that a group of non-OPEC oil producers led by Russia have agreed to collectively cut 2017 production by 600,000 barrels..." said Laskoski.

"But on the other hand the promises for next year do little to change the robust global supply we have today. OPEC's November output rose 370,000 bpd to 34.19 million bpd, a record high.  Reuters reported that Russian oil production for November also set a new record. Nobody's saying anyone will cheat on the agreement but old habits are hard to break," he noted.
