Rey “R.T.” Trevino, oil and gas expert and CEO of Pecos Country Energy, breaks down the latest gas market trends. AAA reports the national average price for a gallon of gasoline is $3.08, down five cents from last Monday and lower than last year’s $3.20. With demand at a four-month low and the seasonal switch from summer- to winter-grade fuel, Trevino predicts gas prices will continue to fall in the coming weeks.
