Heating Oil Guide

When Should You Fill Your Heating Oil Tank in CT?

The safest rule in winter is to refill before your tank reaches roughly one-quarter full, then adjust based on weather forecasts and your home's usage trend.

Simple refill thresholds

  • Fall and spring: plan a refill around 1/4 to 1/3 tank.
  • Peak winter: refill closer to 1/3 tank for extra buffer.
  • If your household is away often, use a bigger cushion.

Why timing matters

  • Cold snaps can burn fuel faster than normal.
  • Storms may reduce route flexibility and increase delays.
  • Running fully out can require priming/restart service.

Monthly planning checklist

  1. 1 Check tank level weekly during winter.
  2. 2 Review forecast for long cold stretches.
  3. 3 Place your order before urgency builds.
  4. 4 Keep driveway and fill access clear.

Tudor Tip

Check your tank level indicator at the same time each week during the cold winter months. Letting the tank drop below 1/4 can stir up sediment from the bottom, which can clog filters and burner nozzles.
