Home-heating oil is similar to #2 diesel fuel but is slightly less refined and lacks certain additives used to improve diesel engine operations.
All petroleum fuels deteriorate over time, so when the furnace is off the fuel goes bad. Diesel is now less than a 90-day fuel – it will still burn, but will produce less BTU’s.
As the fuel deteriorates sludge and varnish build up in the bottom of the tank which, over time, can block the fuel line completely.
If the tank is outside, daily and seasonal temperature changes will cause condensation, which will form water that settles to the bottom of the tank and may eventually get into the supply line – and the fuel line may freeze in the winter.
Water and sulfur in the fuel form a weak acid that will eventually cause the tank to rust from the inside.
Home-heating fuel is a friendly environment for microbe growth, which can block the whole fuel supply line. These microbes grow especially well when there is any water present to aid respiration.
K100-D or K100-MD (for Storage): 1 Quart Treats 250 Gallons to:
- Stabilize fuel and keep it fresh
- Dissolve old sludge and varnish deposits to keep the system clean
- Encapsulate any water in the system so there is no free water to support microbe growth, rust and corrosion or winter freezing
- Clean the burner tip to allow a better spray pattern, giving a more complete burn and better furnace efficiency.
- Clean the heat exchanger plates, giving better heat transfer so the furnace works more efficiently
