This is one of the most common questions that we get asked by our customers. Buying oil has become increasingly expensive as of late, and every homeowner wants to know that their tank is in shape to withstand all temperatures to ensure their safety. We’ve covered this question in our past blogs, but it comes up time and time again and stirs up even more questions. So, we hope to walk you through it again in this blog as the weather is getting increasingly cold and oil becomes more of a necessity.

In general, oil prices are the lowest in summer due to lower demand. Of course, any time in the off-season is ideal; however, we recommend summer as this has benefits outside of just monetary savings. Refilling your oil tank in the summer and then keeping it full throughout the year will increase the longevity of your oil tank and ensure the likelihood of fewer (hopefully no) repairs.

One of the critical components of keeping an oil tank “healthy” is avoiding condensation. When an oil tank is damp, microorganisms can breed at an accelerated rate. These microorganisms form a sludge that clog the lines and corrodes your tank. One of the best ways to avoid this is to keep your tank full. When there’s too much air in your storage tank, condensation forms, and as we’ve covered, that’s the worst-case scenario for the well-being of your tank.

Genove Oil and air highly recommends choosing an automatic oil delivery plan.

If the idea of a corroded tank sounds like an unnecessary headache and you’d like to take the guesswork out of buying oil, then we would highly recommend choosing an automatic oil delivery plan. You can get great deals on home heating oil and Bioheat® fuel, and it certainly is a stress reliever. Automated delivery is an easy option that will lock in a set monthly price and ensure that you don’t run out of oil in the middle of a snow storm. Often these services come with perks such as 24/7 emergency service, convenient payment plans, dependability, and the ability to lock in oil prices or pre-buy. We love this option for those who want to save without putting too much thought into the process.

If you like to be more involved and keep an eye on oil prices, the simple answer to the question of when to buy oil is avoiding purchases between late September and April. If you’re willing to buy in bulk, watching oil prices can save you a lot of money. However, you will need additional oil tanks to store your oil when prices are high throughout the winter. If this sounds more appealing to you and you need a source to keep tabs on oil prices yourself, you can stay up to date on the cost of home heating oil in Massachusetts at the website:
