Oil Purchasing Plans
| Purchasing Plans |
|---|
| Guaranteed Rate: Lock in a fixed rate for the season, protecting you from market fluctuations. Choose to lock in from 30% to 80% of your expected consumption in 100-gallon increments or 100% of your expected usage. No prepayment is required, but a nominal fee applies. |
| Cap Rate: Fluctuates like a variable rate but sets a maximum price per gallon. If rates fall, you benefit from lower prices. A $0.25 per gallon fee applies to cover the cost of this option. |
| Variable Rate: Pay the posted daily rate at the time of delivery. The price fluctuates with the market, making it ideal for those comfortable with price changes. |
| Next Steps: If you wish to continue with the Variable Rate, no action is needed. To enroll in the Guaranteed Rate or Cap Rate, call our office anytime for details. |
No matter which purchasing program you choose, you will still receive the same quality service you have come to know and trust. We know you will have questions about these various options, so don’t hesitate to call. Once again, thank you for choosing Thurston.
Anti-Gel Additive
During colder months, heating oil can thicken and restrict fuel flow, potentially shutting down your system. Our optional anti-gel treatment lowers the oil’s freezing point, preventing blockages and ensuring smooth operation. This additive enhances efficiency, reduces the risk of clogs and costly service calls, and helps maintain reliable warmth all winter long. For homes and businesses in cold climates, it’s a simple yet essential step to keep your heating system running smoothly.
Oil Tank Installations/Removals
At Thurston Energy, we offer oil tank pump-out, removal, and installation services to ensure your heating system remains safe and efficient. Whether you need to remove an old or contaminated tank, install a new tank, or simply need a pump-out to clear out remaining oil, our team provides professional and reliable service. We ensure that all work is done in compliance with regulations, providing you with peace of mind that your oil tank is properly maintained or replaced.

"Thank you so much for allowing us to use your large tank for the weekend of the Harvest Moon Festival. You helped us raise money for Troop 138 and had a great time doing it."
Sherri Lacroix
"Carl, Thank you so very much for coming out late on a Sunday night to deliver oil and restart our furnace. I know from lots of personal experience that being on call is not always fun, but I was so grateful that you were. I had just driven 9 hours with 3 kids and my sister to clean out the house for renters, we were exhausted and when we came into the house and found it freezing cold, I really didn't know what to do, and honestly never expected anybody to be able to get out that late."
Angie, Sarah, Jay and Logan Danek
"Thurston Energy has serviced our needs for 5 years. They have been very reliable and always responded promptly whenever we have had a problem. When one of our furnaces gave out they were here the next morning, offered possible solutions and installed a new furnace the same day! Their technicians are true professionals who take pride in their jobs and truly care about the customer. Thurston is a well run business and I would recommend them to anyone for their energy needs."
