Expiring tax credit to drive CNG prices higher

Expiring tax credit to drive CNG prices higher

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.

The cover story in the August 2009 edition of Fleet Maintenance looked back on the first two years of 2007-EPA emission compliant diesel engines for commercial trucks. The EPA had mandated that starting in 2007 all new on-highway diesel engines must limit the emission of particulate matter (PM).

Biodiesel tips every fleet can use

1. Understand your OEMs’ warranty position on biodiesel and communicate with them your desire to use biodiesel blends in your diesel vehicles. For more information on OEM support for biodiesel, visit www.biodiesel.org/using-biodiesel/oem-information.

2. Ensure the biodiesel meets the ASTM specification for pure biodiesel (ASTM D 6751) before blending with petro diesel. Write these ASTM specifications into your fuel supplier’s bid specs.
