"For its eighth straight week, the national average has declined even as oil prices have bucked the trend in the last week, moving higher on optimism over upcoming trade talks between China and the United States," said Patrick DeHaan, head of petroleum analysis for GasBuddy. "While most of the country saw gas prices continuing to drop, it certainly was not all. The West Coast has gas prices rise gently in recent weeks, but those increases likely won't last. Moving forward, I believe the market will closely watch the October trade talks and any comments made between the countries until then, and gas prices will track with optimism- should there be a positive conciliatory tone between the two, we may see a more organized, but temporary, upward move. If trade talks fall apart, then expect more price declines that will accelerate in the weeks ahead. Markets have been reliably unreliable in recent weeks and it seems that will likely continue as the talks hold significant meaning for oil and gasoline demand."
