“My wife and I try to reduce our environmental impact as much as possible. We were able to choose a B20 Bioheat oil blend for six years, and then we immediately switched to B30 when that became available. And when Cubby notified us last year that they were increasing the Bioheat percentage to B40 (40%), we were excited to reduce our carbon footprint even more.”
—John P. from Newton
