Gas Prices

Please note that CARB diesel has been combined with EPA on-road diesel.
This is done to track refinery capacity for overall diesel production.
The yellow area denotes the highest and lowest production or inventory levels for the past five years.

Carp and EPS Diesel Inventories.

For much of the past year, diesel production has been consistently at or above average historical levels while inventory levels have been consistently below average. This implies that demand has increased, preventing inventories from attaining average levels.

For the first quarter of 2005, diesel production was maintained at a high level in response to increased demand from the farming sector. The demand is evident with the decrease in stock levels despite the high rates of production. For April, diesel production consistently stayed at or above production highs of the past five years.
This constant high output of diesel fuel kept inventory at a steady level due to robust demand.

A gallon of gasoline in California contains approximately 111,500 Btu (which is the standard for British Thermal Units). By comparison, M85 contains approximately 65,000 Btu/gallon and E85 contains approximately 81,000 Btu/gallon. The lower energy content of these fuels will result in fewer miles per gallon or a shorter driving range.

What is Low NOx Software Upgrade?

Low NOx software upgrade is computer programming for electronic control modules in certain heavy-duty diesel engines that reduces excess emissions of oxides of nitrogen (NOx).

Owners of most 1993-1999 model year California registered heavy-duty diesel trucks, school buses, and motor homes, and interstate vehicles that visit California, with engines manufactured by Caterpillar, Cummins, Detroit Diesel Corporation, Mack/Renault, Volvo and International have an obligation to have low NOx software installed. When installed, the low NOx software reduces NOx, a component of smoke.
