Home heating Oil (hho) Is the same as off road. In some rare cases it may still be LSD instead of ULSD but even better for you if so. Dont get hung up on the sulfer content though, just add something for lubricity, i wont get into the argument over that, some use trans fluid, power stroke, or 2stroke. So yes you can just go to an oil company and buy it from them, they usually have Offroad as well, and sometimes there is a different price even though its the same product. Ive been told HHO is more as they anticipate dragging a hose to the tank, while offroad is in a place where equiptment can be driven to thus all they do is pull up and fill it up. But when i called a place Offroad was more :confused2: even though i said to them "its the same thing", she responded yes and said the 2 different prices? :confused2:
Anyway, if you have to drive all over to find OFFroad or HHO your just as well off buying deisel at any pump. The price of fuel these days if you cant just stop by on the way somewhere its not worth the effort to go out of your way to save $.25-.35 / gallon. I have the last 2 times gotten onroad as the offroad place was not close or either closed. If your putting it in your yanmar you can go through what 5 gallons a weekend? Maybe 30 a year if your using it a lot! Or do you have other offroad deisel applications?
So my point if you can find a local close or HHO company near you fill up some old hydro buckets and cans to last you a few months or just go to the onroad pump.
A tip is find an area that has loggers and go to the local family owned gas station they will most of the time have it, but there the ones that are higher so you may only save .20 over buying deisel at say a racetrac or other cheap station in your area.
