Natural gas vehicle drivers will likely see their gas prices go up at least 50 cents a gallon after a federal tax credit runs out at the end of the year.

ONRL & GM prototype low-viscosity ionic liquid-additized engine oil delivers 2% fuel economy improvement over 5W-30
A team from Oak Ridge National Laboratory and General Motors, led by ORNL researcher Dr. Jun Qu, has developed a new group of ionic liquids as lubricant additives that could help improve the energy efficiency of cars and trucks.
Prototype low-viscosity ionic liquid-additized engine oil demonstrated a 2% improved fuel economy compared to Mobil 1 5W-30 engine oil (3.93% over the 20W-30 baseline oil) in standard fuel efficiency engine dynamometer tests. The prototype oil also successfully passed a 100-hour high-temperature, high-load engine dynamometer test.
