Default diesel fuel vs HHO?

Thinking of bringing a five-year-old creampuff Mercedes B18D diesel home to pair up with my XJ Sport 2000. Question: in a pinch, can I tank up with home heating oil?
Aware that fed tax is an issue, and I am law-abiding but curious anyway.
I have read Yes in a Google search, and I have read No. Anyone out there a fuelhead?

Very strong probably.

Since the mid-2000s, almost all #2 Fuel Oil has been the same rack product from the refinery. A couple decades ago they were dissimilar, but with modern emissions standards, all #2 Fuel Oil must be ultra-low sulphur (2008 was the last cutoff, I believe). To be sold as diesel fuel, the oil must meet certain requirements, such as minimum cetane ratings. Home heating oil may or may not hit these performance numbers, depending on your market, so it's a good idea to add some PowerService or whatever you like to boost the cetane rating. In my area, however, stove oil and off-road diesel are literally the same thing.

If you want to see some serious fuel nerds at work, pay a visit to forums.tdiclub.com. Not exactly your engine but fuel knowledge is universal!

It's the same stuff, except for the dye. I run HHO in my tractor because I get it for free. No problem.

1995 Cummins 5.9 diesel with a p7100 injection pump runs just fine on heating oil. It runs on 2 stroke cut with diesel. Straight motor oil runs just fine.

HHO may or may not have the same lubricity as D2. Otherwise it works just fine, I have a client with an 80's era MB W126 W/om617 5 cyl diesel that runs just fine on HHO. Ditto for the 6 cyl MB diesel (sometimes he runs that on jet fuel). To make sure the injection system gets enough lube he mixes a quart or so of ATF or two cycle oil per tankful of fuel. In the winter he mixes in a few ounces of PS or Howes to prevent gelling. I run a Detroit 4-71 on HHO mixed w/B99. The old Austin London taxis (60s era w/Perkins) were designed to run on HHO.
