#2 oil vs Diesel

[smitty]

? I like to run #2 in my cummins 6b. But is it worth it?

#2 diesel is a specification for heating oil. Its physical characteristics are the same as motor diesel. It doesn't have to meet motor diesel's cetane (compression ignition capability), lubricity (affects injection pumps) and other specs.

Sometimes it will meet those specs because refiners don't make any distinction between the two, but sometimes it doesn't. It depends on the refinery supplying your fuel pumps.

You pays your money and you takes your chances.

Every lonsterman around here has been using it for as long as I can remember, But we do replace engines every 20 years because they get 25 or 30 thousand hours on them.

What are your concerns?

 

[smitty]

Getting stuck out at the canyon! But maybe iam just thinking to much!

Smitty,i have used both and i cant see any difference

We bunkered the ship i work on with 786,000 gallons of Marine Gas Oil, aka #2 fuel oil the day before i left. We burn around 15000 gallons a day and never had an issue. The whale watch and tour boat I help run in the summer both run #2 diesel oil through detroits, and havent had an issue with the unit injectors in well over 10 years. I run it in my boat, and will keep on doin so!!.

 

[smitty]

Next time i fill up. I will give it a go. thank you men.

Some very interesting points here. Let me ask you this. What about additives?

I know when we buy bulk oil, aka for the ship we have to dose it for its low lubricity properties. We see that in our bunker samples of that sulfer.

The question is when you buy it off the truck or at a marina, what has been done to it? My understanding is that it has a lubricity additive put into it, as its being sold as shell, texaco, etc.

 

[smitty]

i use Stanadyne.

 

[WoundUpMarine]

shawn what do you put into it for an adative?? the only thing we put in is amerstat 25.

It's my understanding that you can't run it in a tier II motor. The " dirty fuel " wipes out injectors & pumps because it's designed to run on ULSD. It also stinks when you burn it. If I get straight ULSD the exhaust burns clean. If the truck had some leftover #2 oil in it and it's mixed with the ULSD, you can smell it in the exhaust immediately.

I lost speed and gained soot
Never again, only diesel for me
The higher the cetane level the better

I use Aronol in my boat, works great
Aronol Diesel Fuel Additives Heating Oil Detergents & Conditioners

Plus they sponsor the races, we give away cases of product at Searsport

We use Drew Marine as well, Amergy XLS, its for ultra low sulfur fuels. They make us do it to protect fuel pumps, etc. Remember I'm working for the Navy, they demand we use it and go after people who do not. They can tell and have heard of fuel system issues. Its nice too because the Amergy XLS, also has the Amergy 222, which can take care of residual heavy fuels left over in bad bunker barges, etc. It basically grabs it and drops it to the bottom of the tank, your choice where you dose it, as do you want to screw up your storage or settler tanks...

On my ship we dose Amerstat 25 with the biocide and then Amergy XLS for lubricity. Now if Drew only sold them by the quart!

"tier 11 motor" ???

Tier 2 compliant engine
We're on tier 3 currently
Tier 4 starts in 2014

The big companies will not fuel you up with #2 (because it's all illegal and stuff)

If I'm reading that right tier 1 started 2003
So my 2001, what were the standards then ?

As WoundUpMarine and CEShawn, I too work on ships and like Shawn am responsible formaking sure the fuel we bunker will burn. With todays regulation ULSD is becoming commonplace. We are talking 0.000x% of sulfer. So we use the additives on motor ships.

#2 fuel will work fine in your boat, the problem is I have never seen a spec sheet when they deliver it to my home boiler. So what are you getting and what is important? #1, the flash point and specific gravity. #2 sulfer content, #3 cetane index you want a min of 40, mid 50's is better, finally take a look at the ash content.

So this will work no problem but just remember as others have stated there are more specifications put into road diesel, or Marine Gas Oil, the Navy uses F-76 Diesel fuel Marine, which is just a bit better quality diesel "with different specs".

Got you worried?, then stay with the diesel. An old timer would use the #2 off the truck and dump some mystery oil in the tank.

I could go on more.....one other thing is your engine, are you using a higher speed engine like a yanmar doing 3000+ rpm or running at 2200. The higher speed requires a bit quicker ignition so it won't lag. This isn't a concern on a ship but is on smaller craft.....

that's enough.....FWE

Thanks for all this info. I've got a brand new QSC8.3 and I'd be insane if I put #2 in it... Too risky for me.
