Since taking over the ordering of this product for our company, I have found that this product not only meets our needs for our Tractors, but also cost effective as well. Shipping directly to us and ordering in bulk, makes this very cost effective.
I live in New England and the recent freeze drove temperatures below 0 or lower (if you take into account wind chill) for over a week. Needless to say, my outdoor oil tank line gelled up causing oil to stop flowing and as such my heat shut off. My oil service provider said there wasn't much they could do and it would just need time to thaw out. He mentioned Diesel 911 might help.
Given the forecast was showing another week of single digits temperatures, I started to call around trying to find this product. Apparently, so was everyone else. There was such high demand for this product, I was only able to find two bottles at a local automotive store. I grabbed both bottles and within hours, my heat was back on. I really lucked out finding this product. I decided I would never be in that position again, having to search high and low in frigid temperatures and ordered a small supply to have on hand if or when needed again. This is the only product I will ever use for gelled oil in my oil tank line.
I use this on home heating system outside oil tanks. This product works great on gelled oil tanks.
Wouldn't be with out 911. Have big rig, tractor and pickup. All diesel keeps everything running great.
