ULSD / ULTRA LOW SULFUR DIESEL

We have #1 and #2 diesel available year round. Clear for the on road users and dyed for off road use.

BIODIESEL

Keck Energy has received the Iowa Department of Agriculture’s “Biodiesel Retailer of the Year” award for our strong promotion of Iowa produced soy biodiesel. We offer blends from B5 all the way to B99. The ULSD diesel fuel can benefit from the additional lubricity of biodiesel, and the biodiesel blends do a great job of keeping the injectors clean.

GASOLINE

Regular unleaded, E10 gasohol or even higher blends such as E15 and E85 are available. Ethanol blended gas help our local farmers and keeps fuel dollars here in Iowa.

PREMIUM FUEL ADDITIVE

Increases the cetane, lubricity and long term storage characteristics of the fuel.

BIOCIDE TREATMENT

Becoming more important now that the sulfur has been removed from the diesel. Dark, wet and warm surfaces encourage the growth of micro organisms referred to as bugs, bacteria or fungus. Left untreated, they accumulate and form a blackish slime which plugs your filters and injectors. Best treatment is a regular application of biocide, or, if conditions warrant, a “shock” treatment is required.

COLD FLOW ADDITIVE

When the temperatures are expected to be lower than a plus 10 degrees, a cold flow additive is highly recommended. This additive lowers the cold filter plug point “CFPP” by 15 degrees. When the temps are going to be well into the negatives, a blend of #1 and #2 is highly recommended. Our sales staff can give you advice on the proper ratio, based on the weather forecast.
