This coming weekend will be extremely cold. Please make sure you have enough oil in your tank! If you have an outdoor oil tank, insulate your oil line and put an anti-gel additive in the tank.

We can not stress this enough … if you have an outside oil tank, PLEASE get some heat tape on those oil lines. With temperatures as low as they are, your lines will freeze.

Insulate those lines from outside oil tanks!

Do you have an outside oil tank? With temperatures as low as they are, especially for an extended period of time, you may experience your lines freezing. We strongly recommend insulating your oil lines with heat tape. It’s an inexpensive fix to make sure your system stays running properly. Can be purchased at Lowe’s or Home Depot.

Meet the newest member of Bertrand Oil Service! Congratulations to Anthony and Robyn. They welcomed their daughter, (our first grandchild), Valentina to the world on December 11th. While she won’t be ready to join Daddy and PopPop out in the field for quite awhile, Gigi has definitely already crowned her employee of the month!
