Either one, and no oil needed.

 

No worries, you will ony be able to find ULSD in the good ole' USA...
"United States
As of September 2006, on-highway diesel fuel sold at retail locations in the United States is ULSD[4].

Ultra-low sulfur diesel was proposed by EPA as a new standard for the sulfur content in on-road diesel fuel sold in the United States since October 15, 2006, except for rural Alaska. California required it since September 1, 2006, and rural Alaska will transition all diesel to ULSD in 2010. This new regulation applies to all diesel fuel, diesel fuel additives and distillate fuels blended with diesel for on-road use, such as kerosene, however, it does not yet apply to train locomotives, marine, or off road uses. By December 1, 2010, all highway diesel will be ULSD. Non-road diesel transitioned to 500 ppm sulfur in 2007, and to ULSD in 2010. Locomotive and marine diesel also transitioned to 500 ppm sulfur in 2007, and to ULSD in 2012. There are exemptions for small refiners of nonroad, locomotive and marine diesel that allow for 500 ppm diesel to remain in the system until 2014. After December 1, 2014 all highway, nonroad, locomotive and marine diesel produced and imported will be ULSD..."

 

You can buy LSD in many places (like many Flying J truck stops) except the state of CA. The EPA allowed the sale and use of LSD for on road use until 2010 so long as 80% of all diesel made is ULSD. IIRC all refiners have to stop making LSD for on road use by the last day of May in 2010. Also you don't need to be using any 2 cycle oil as its not needed.

 

thanks fella's
