I've had better service from them than Generac engined units. Mitsu is good though.
I got a new Generac 10K that woldn't run, and when I brought it back they had me unload it next to 5 others just like it.....

Not true here. Legally, number 2 fuel oil has a lower cetane, worse cleanliness spec, higher cloud point, and wider lubricity spec than ULSDon road fuel.

From a practical standpoint, all of our local distributors simple sell the same fuel as on road, off road, and home heating oil because of storage and tankage issues.

I think that’s the case through most of the country.

Fuel oil has largely fallen out of favor as a heating fuel, so it makes sense for the distribution network to commonize product.
All fuel oil sold in US is low sulphur. How can you share on and off road as same product when one is dyed? Fuel oil, Off road and on road are all different products. Some dealers may sell off road and fuel oil as same product but in cold climates that ain't going to work out to well when fuel oil congeals

The most GJ way is to get a big 3 phase diesel generator to run some machine tools from and just use it as backup in case of power cuts. I actually know someone who did that here in the UK as it was far cheaper than getting the large 3 phase supply they needed.

Why not just run a VFD?

it's the same stuff man. They all fill up at the same fuel depot. It's not worth the effort to bring in two different, nearly identical product. It's all ulsd. #2 fuel oil gets dyed, on-road diesel does not.

As i said earlier in this thread, we've been renting a 200kw diesel generator right from one of the biggest cat dealers in the northeast. We use their fueling service. Every monday a home heating oil truck shows up and pumps 200 gallons of red dyed #2 fuel oil into that generator. You better tell the cat dealer that they've voided their own warranty...

Ah yes, a cheap and nasty chinese diesel generator is just what i want for a backup generator.

hopenn?

Around here most HHO tanks are inside. The ones that are outside mostly are for mobile homes, and the oil companies normally will fill it once with oil, then the next time with kerosene to keep it from gelling.

What about a NG backup generator, with a large propane tank as backup if the NG is cutoff? Most generators can be configured for either fuel, and a tank of propane would not require the recurring maintenance of a large tank of diesel fuel.

I assume you would need to swap out fuel components in the generator to switch from NG to propane, but that would only be needed if the NG supply was cut off and you decided to switch to propane. Or do I misunderstand how it might work?

What the delivery truck says .... has nothing to do with what's in the tank. There are different grades for what you are talking about .. it is what it is. They may do all the deliveries of that fuel on Monday with that truck .. who knows. The people fueling the generator know what to buy and get delivered.

I can order different fuels .. they are not all the same.

I literally talked to the delivery guy. He said it's the exact same fuel they put in houses. It's not even the same home heating oil company every time. Just whatever local company is available at the time. Reality doesn't fit with your narrative.

Is the delivery guy some sort of chemical engineer ??

Not to be flippant ... I have no idea what comes to your local terminal. I'm just telling your there is a difference. They are backward compatible .. you can burn the cleaner in a furnace.

The reason I know it's still an issue. Outside of my city property/ office all last summer ... there was a semi truck (it was a huge portable boiler) ... the city had a water main crack and they needed this contraption to keep part of the steam loop running (that's what they said). It also needed a generator -- I guess they could not connect it to the grid ?? Big generator w/ a separate tank. The fuel for the generator was diesel and the fuel for the boiler was #2 ... since it sat out there 24/7 for months .... I actually saw them test the fuel for the generator. It all got delivered by the same company -- a fuel oil company. Different deliveries. They had a guy watching it 24/7 in a separate truck.

Maybe there are markets where it is not economic to transport various fuel grades -- so it's all the same higher grade product ?? With the refineries in the mid-atlantic -- it's available.

The guy has bigger kit in his home shop than many actual engineering shops, rebuilds steam engines for fun. When one of our pallet forks got bent we took it there and he bent them back on his 100 ton hydraulic press, VFD's are not cheap once you get big and need a lot of them. He could have got a 3 phase supply but they are expensive to have when you only use the power some of the time.

well thats beyond most home shop grade kinda stuff.

but a 100ton press could be run off of some 9v batteries and a century worth of time. unless you want decent cycle time.
