Is using domestic heating oil detrimental to your diesel marine engine?
hypothetically if it was legal of course

I know that when I worked at a large airport all the ground power diesel engines were run on JetA1 fuel which is basically kerosene. Apparently with no problems. Much wou;ld depend on what heating oil is. There may be some question of lubrication properties for the fuel pump and I imagine heavier oil might not go through the injector so easily so giving less power or more throttle required. i dunno olewill

Search back. There are gigabytes of stuff on the topic. And yes of course it works. Legally if you declare your engine a diesel heater you might even get away with it. Its just a not a so efficient heater as it looses a tiny bit in mechanical energy. But basically its just a waterheater.

30 sec oil is a bit on the thin side - lacks lube properties - you could thicken it up a tad by adding veggie oil from the supermarket, but would need to check first to make sure they mix ok.
BTW, vegetable oil has a much higher lubricity rating than any mineral oil, and would be ideal as engine lube oil if only it didn't oxidise so readily into a solid fat. Indeed, Castrol got started by using Caster bean oil (hence the company name) as a base stock.
It's currently perfectly legal to use vegetable oil as a road diesel fuel in Britain, therefore a boat should likewise be ok - dunno about the heating oil though.

Fuels
Simply it depends on the set up and design of the engine mechanics verus the burn characteristics ( speed of flame advance in cylinder as detonation occurs ) of the fuel.
Thick textbooks have been written about this but any engine will run if the fuel burns to expand the fuel/air mix quick enough to move the crank around fast and long enough to get to the next power stroke BUT some lower quality fuel ( lower cetane numbers etc) may be still burning when exhausting and thus burn exhaust valves and lubricating oil off the cylinder walls - rapid wear of engine then takes place. Conversely more volitile fuel may burn too quick and what is called 'knock' then is heard and you run the risk of too much pressure on the small and big end bearings just before TDC and bearings then fail quickly.
Selection of different fuels has always been a matter of how much power you want, how long you want an engine to last, how much much maintenance you want, verus fuel cost, fuel handling etc. ( Heavy oil needs preheating etc)
Loads of people are trying to put cheaper fuel into engines these days, so you are not alone, but this is not new Diesel himself started out with cheap coal dust in his first compression ignition engines. TVO was cheaper than Petrol hence its use in the 1950s Little Grey Fergi Tractors etc

Heating oil is sold with a specific warning against being used as road vehicle fuel. Look at the printout from the delivery tanker.

found this on Wiki - read No 2 fuel oil
Fuel oil is classified into six classes, numbered 1 through 6, according to its boiling point, composition and purpose. The boiling point, ranging from 175 to 600 °C, and carbon chain length, 9 to 70 atoms, of the fuel increases with fuel oil number. Viscosity also increases with number, and the heaviest oil has to be heated to get it to flow. Price usually decreases as the fuel number increases.
No. 1 fuel oil, No. 2 fuel oil and No. 3 fuel oil are variously referred to as distillate fuel oils, diesel fuel oils, light fuel oils, gasoil or just distillate. For example, No. 2 fuel oil, No. 2 distillate and No. 2 diesel fuel oil are almost the same thing (diesel is different in that it also has a cetane number limit which describes the ignition quality of the fuel). Distillate fuel oils are distilled from crude oil.
Gas oil refers to the process of distillation. The oil is heated, becomes a gas and then condenses.
Number 1 is similar to kerosene and is the fraction that boils off right after gasoline.
Number 2 is the diesel fuel that trucks and some cars run on, leading to the name "road diesel". It is the same thing as heating oil.
Number 3 is a distillate fuel oil and is rarely used.
Number 4 fuel oil is usually a blend of distillate and residual fuel oils, such as No. 2 and 6; however, sometimes it is just a heavy distillate. No. 4 may be classified as diesel, distillate or residual fuel oil.
Number 5 fuel oil and Number 6 fuel oil are called residual fuel oils (RFO) or heavy fuel oils. More Number 6 oil is produced compared to Number 5 oil, the terms heavy fuel oil and residual fuel oil are sometimes used as names for Number 6. Number 5 and 6 are what remains of the crude oil after gasoline and the distillate fuel oils are extracted through distillation. Number 5 fuel oil is a mixture of 75-80 % Number 6 oil and 25-20% of Number 2 oil. Number 6 oil may also contain a small amount of No. 2 to get it to meet specifications.
Residual fuel oils are sometimes called light when they have been mixed with distillate fuel oil, while distillate fuel oils are called heavy when they have been mixed with residual fuel oil. Heavy gas oil, for example, is a distillate that contains residual fuel oil. The ready availability of very heavy grades of fuel oil is often due to the success of catalytic cracking of fuel to release more valuable fractions and leave heavy residue.

35 sec heating oil is similar to diesel and 28 sec oil is similar to paraffin. i have used the remains of a tank of 35 sec oil in my car with no ill effects - so far!

I think I might be inclined to try it in an old slow speed type diesel engine but I wouldnt in a modern high speed common rail car engine. People have previously said that red diesel is coloured gas oil rather than coloured white diesel
But why not just do what I've seen some people do and buy red diesel from your local farmer. Personally I use so little that it isnt worth the aggro but you might think differently.

For the first time ever, I saw red diesel for sale at the roadside this week. Little old country filling station on the A354 had reduced down to just one pump and was displaying a sign 'RED DIESEL 75p - sorry no petrol', Guess that was for local farmers.

My local garage sells it from the pump as well, 67p last week, trust it is for tractors etc.

Possibly, but may depend on your engine. Many years ago I owned an ex fishing boat fitted with a Gardner diesel. The hand book said that it would run on lamp oil (presumably paraffin) but as this had no lubricating effect some oil had to be added to prevent wear of the injector pump - it suggested used sump oil, but I can not remember the proportions.

It used to be half a pint of straight 30 engine oil per gallon.

This is when we need Refueler back in the pack to give us chapter and verse on this subject.
Red gas oil is sold roadside to the likes of refrigerated vans as well as tractors.
My understanding is that UK motorists can make (500 gall?) and use bio fuel without the need to register for duty or VAT providing it is for own use.

Where does ex-chip oil feature in the equation?
The Welsh were up on that for a bit and the smell in some towns was very appetising.

Chip Oil
Used Chip Oil is not a good idea as it contains starch and other solids from the frying process .. However you can use new chip oil and it does work but dont dilute more than 50/50. If you do the engine will start to suffer. You also notice a loss of power so fuel consumption goes up. It is however very illegal
