Get it from petro, you'll be better off.
Just a comment offered me the loweI had Petro for 20 yr and I had to call then every year and they never offered me the lowest price. I had to call around and get the competitions price call back and ask again for the price . Then they would come down 20-40 cents a gal. Then one year they didnt match the lowest price whiich was slomins this after 20 yrs of being a good paying customer. I even bought a new boiler from them. So know your prices and be ready to move companies.
