At Quogue Sinclair, our Oilheat is different from the type our competitors deliver. The heating oil we deliver to your home contains Avalux, a state-of-the-art additive that is specially formulated to maximize your energy dollars while optimizing the performance and extending the life of your heating system. Best of all, we deliver this premium grade Oilheat to you at no extra charge! With Quogue Sinclair's FREE automatic delivery service, all you need to do is sit back and enjoy the warmth — no wondering whether your fuel gauge is on "empty" ... no worrying about your family's comfort ... and no waiting for the truck to arrive. By combining your past history with state-of-the-art software, we determine exactly when you are in need of a fuel delivery. We typically plan our deliveries when your tank has used three-quarters of the available fuel plus a safety margin of five days.
