I saw my oil delivery company used this so I ordered. One bottle treats 275 gal.

I had an issue with water getting into my oil tank. This would usually happen after a soaking rain storm or a period of rain over several days. The water would eventually cause my burner to stop running as we know it will not run on water. After spending countless hundreds of dollars, I was told of this product. Simply add it to the tank just before a fill up and it will help eliminate these costly repair bills. Seems to work great as I have not had a repeat in almost a year now. I would recommend for anyone having a similar issue or just old equipment.

Super easy to use and helps keep furnace working well and reduces tank corrosion.

I had been using another brand and switched to Fuel Ox. What a difference. My burner has never been this quiet. It went quiet right after adding Fuel Ox and getting the tank filled. This is now my favorite.

I always used SId Harvey's STR-2+ fuel oil conditioner to keep my fuel oil from gelling and to take care of any water that makes its way into the tank. But they won't sell to retail customers anymore, even when there's no one in the store.I've been using this for the past five months, no issues with gelling or water at all. Works great.
