New diesel older motors

[daman1]

Do I have to add any treatment to the fuel so it is ok to run it in the backhoe?

Yes good idea...why?

older machines like yours(and mine) usually had mechanical injectors and injector pumps and are lubricated to protect against wear by the fuel that flows through them, fuel of yesterday had more lubricity to it then todays "dryer" fuel and just don't provide the lubrication theses older units need.

so yes yes do use a lubricity additive your unit needs it for longevity.

As usual I am probably wrong/out of date/mistaken, But I thought it wasn't an issue of mfg. date, but an issue of if the engine injector pump was fuel lubricated, or sump pressure lubricated, and of the seal/oring material.

right.. modern fuel injection systems are built with LSD and ULSD in mind.... older systems that were built "back in the day" were designed for using the old high sulfur fuels.... Clearances, metals, seal materials..... all designed for use with high sulfur diesel.

The older injection pumps benefit from the use of added lubricity.

There are long, long discussions (with some solid research) on The Diesel Place
Lubricity Additive Study Results - Diesel Place : Chevrolet and GMC Diesel Truck Forums is one of the threads.

As I recall, one of the best solutions for older engines is 2 cycle outboard motor oil (as already mentioned here). Some of the other products are more expensive and less effective...or not effective at all.

YMMV.

Well, I've been wondering the same thing. The seals went on my 2.8 litre Toyota ute (pickup) a while back. That was sweet as BP paid for the pump overhaul - $800 + in a huge compensation package. Thanks guys. I keep an eye on my 20 yr old Ford 4110. No leaks yet - but I'm sure BP will not come to the party again. A full pump overhaul out here is around the 8 to 9 hundred $ mark. That includes 12 months warranty. If you want to just get the seals done, it's about 5 hundred, but has no warranty. I figure it's false economy to just get the seals when for a bit more the whole thing is newed & covered. Cheers, Ged

Hi Folks,
I just had some diesel delivered for my bulk tank. I have a loader/backhoe that is 30 years old. As I understand it current diesel fuel is low sulfer content. Do I have to add any treatment to the fuel so it is ok to run it in the backhoe?

No.
The lubricity of the fuel as blended is adequate.

As with shark repellant in an inner city community pool, you don't NEED it, however some folk just "feel better" knowing that they have it.
Folk know that sharks a) swim b) sometimes bite humans - - so they conclude that shark repellant is needed any time they are in water.

If you are of the "If some is good then more must be better" persuasion, then go ahead and pour in money.

BTW, "Its cheap insurance" and "Three bucks of additive is a lot cheaper than a $6K engine" are both true statements, though irrelevant since the NEED is not there.

On what do you base your statement? Government bureaucrats with who don't care if your ten year engine fails and you have to buy something new?

Have you read the thread I mentioned in The Diesel Place? I trust that more than the government BS.

I KNOW that I do not trust the oil companies to provide proper lube for ANY of my diesel engines. The additives are worth the price even if they are not needed because I sleep easier knowing that my equipment is protected.

A set of fuel injectors or one pump cost more than a couple of lifetimes of additives.

I too believe the article in The Diesel Place more than ANY govt crap.

Incorrect above statement,,talk to any reputable fuel injection rebuild place they'll tell you on older systems a lubricity additive is very highly recommended.

lubricity additives are blended into todays fuel yes BUT it is by no means enough for older systems.

That sounds very much like;
"A vial of shark repellant is a lot cheaper than surgery to have a limb re-attached, or a funeral."

The cred of those who scribble in the Diesel Place is hardly above reproach, but we read what we believe - and believe what we have decided to read.
