So Brown's loosening of the rules on gas blends is an attempt to fight back against that vulnerability and bring prices back down. The different grades of gas are measured on a system of RVP, or Reid Vapor Pressure, which is measured in pounds per square inch (PSI). Flickr / m, credit: flickr / m, lots of drivers out there probably didn't know (or care) that gasoline is blended differently for summer or winter.

The nation has some 20 different blends of gasoline to meet overlapping state and federal guidelines. Tesla Motors has announced a quarter-million orders with cash deposits for its new Model 3 electric car. Department of Energy figures tell us that the overall mix of the.S.

Or, sync up your compatible devices for instant fun. A major argument for government-subsidized electric vehicles (EVs) is the reduction of greenhouse-gas carbon dioxide (CO2) emissions. For example, in winter you can blend butane, which is relatively plentiful and cheap, with gasoline. Recently, though, that issue has been capturing headlines, thanks to a showdown in California, where Gov. More people travel in summer during peak driving season, for instance, putting more stress on demand.). Hybrid electric vehicles (HEVs plug-in hybrid electric vehicles (phevs and all-electric vehicles (EVs) typically produce lower tailpipe emissions than conventional vehicles.
