I thought I'd ask if there's anyone who knows what the current heating oil Sulphur levels are in Pa. consumer #2 heating oil.
I did some digging around on the web and found that the PA. limit dropped to 500 ppm on Jul 1, 2016. It had been 2000 to 5000 ppm, depending on the area of the state. I know that NY and some other states are already requiring ULS heating oil at under 15 ppm. I'm guessing that 500 ppm oil may be enough to keep microbial growth at bay? If we are even getting that level.
My main concern, in Pa., is that the same fuel sold as diesel fuel ( ULSD) is being passed on to heating oil customers anyhow. I know that my heating oil dealer also handles gasoline and on and off road diesel. As do a couple of other dealers that I can think of. I also read that the Sunoco refinery in SE Pa. only makes ULSD now. Sunoco is the supplier for most of the gasoline and diesel stations around here, regardless of brand.
Do any forum members in Pa., work in the heating oil business and can tell us? Most of my home heating comes from a hand fired coal stove, but I burn ( too much) heating oil year-round for DHW and a little heating in the shoulder months. I'm going to start using Biobor JF. I started using some anti-gel stuff last year. I have an outdoor tank, about 14 years old. I had never added anything but 15 or 20 gals of kerosene in the Fall.
