How to save on heating oil in Connecticut
The best way to save is to compare at least 3 local dealers before ordering — prices between dealers in the same area can vary 10–20 cents per gallon. Buying in the off-season (May–August) when prices are typically lowest, or signing a price cap contract in spring, can also save 15–25 cents per gallon. Set a price alert to be notified when prices drop to your target.
