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.

The following website is an excellent resource and overview for all fuel-type information and statistics from the most populous state in the U.S.: California. The heading, Transportation, is frequently updated and full of statistics, charts and other useful information: 

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.
