<font color=blue>… My guess is the Quickie-mart sells winter fuel year 'round?…</font color=blue>
No… it's whatever the supplier does… usually from about Mid October to End of April in NE US region will be winterized fuel… So soccer-mom is unaware of any changes to fuel… Most fuel stations will have signage posted stating “Winterized 1-D Fuel” on the pumps for the truckers…
Also most fuel suppliers will have limited tank storage and inventory and will only have 1-D available at their site… so delivery of “home heating oil” to that customer/farmer with the tank mounted “outside” will get 1-D fuel oil during the winter months…
{besides their supply tanks would “gel up” with straight 2-D fuel in the winter also…}
<font color=blue>… more hp than the winter blend…</font color=blue>
Yes, regular 2-D fuel has a higher “BTU” per gallon than blended winterized 1-D and “gasoline”… so in essence another reason you get better mileage and more work {horsepower/torque} from a diesel over gasoline engine…
<font color=blue>… what would happen if I have a more than 50/50 blend of Kerosene/diesel - would too much kerosene make it run rough? What would happen if I had 100% kerosene…</font color=blue>
Normally, after you cut your tank {mix 50/50}, the next time you buy fuel in the NE at the pumps… it will be winterized… so you won’t have to mix it again. On a severe sub-zero cold spell, running straight kerosene is not unheard of… but usually you will have hydraulic problems at this temp. stage {even with so called synthetic expensive hydraulic fluid…} The major disadvantage of running straight kerosene
tank after tank is you don’t have the “diesel” lubricant properties the diesel engines need over long term usage…
Note-The winterized fuel comments are made pertaining to the Northeast U.S., I’m sure San Diego, CA. and Tampa, FL doesn’t know what 1-D fuel is…so obviously mixing kerosene with diesel in those area’s shouldn’t be done as it would be unnecessary…
