We have 2 small diesel tractors, 35 and 45 hp, the 35hp (Oliver Super 55) was inherented from my father. It had the dreaded black goo in the fuel system. It is almost back together after a full engine rebuild. What diesel additive should I use to avoid a return of the black goo?
Thanks

For decades i have used power service with good results in my diesel engines, but really anyone would be better than nothing

+1 for Power Services, have also used for several years and it works!

Years ago we had the dreaded diesel Oldsmobile. We used to buy cheap fuel in Mexico and would store it in 55 gal drums. The black goo might be algae growth. Biobor was what we used for this plus an added Racor water separator/filter.

I drove Mercedes diesels for 35 years. I used nothing but Howe's and even put 425,000 miles on one.

the Black goo in diesel fuel is most defiantly Black algae! and Power server or Howe"s will do nothing to prohibit its growth. it is very common issue in seasonal use equipment. and a real pain.
Regardless of how many miles one has on there vehicle or how many years one has used P S or Howes, Black algae is a problem if you get some contaminated fuel.
Most auto part stores sell an algicide product specifically for diesel fuel and it matters not what color your diesel fuel is. Once you tank has been introduced to a batch of fuel with algae growth in it, only an algicide will kill the algae but you still have to filter the dead algae out, eliminate the black goo.
If your local auto parts store doesnt have the algicide for diesel then go to a fuel oil supplier and get it there.
Your old Oliver was designed for fuel with sulfur in it to lubricate the injection pump and injectors. you tractor most likely has a Wakashaw engine with a Rossamaster injection pump. You can use anything from clean used engine oil to the already suggested additive for lubrication in the crappy LS fuel.

As others mentioned earlier, all I ever used was PowerService. I bought my fuel from reputable stations and added it year 'round as my diesel was a '92 7.3 and it was suggested after the switch to low sulphur diesel.
Sold it at 420K miles after the body rotted off so I guess I did something right. Never did a thing to it besides change oil and filters and replace the fuel return lines twice.
You need a biocide. I order mine online. It is not cheap but a little goes a long way.
Screwbolts gave you good advice.

Lots of options

This is the one I use. https://www.amazon.com/BIOBOR-Diesel...s%2C131&sr=8-4
The only issue that I have is one oz does 80 gallons and my tank is 24 gallons.

I'm sure many algaecides will work, but I've had good results with fppf killem. When you use any algaecide, keep a few spare filters on hand. The dead algea will look like coffee grounds and plug the filter quickly. In older diesel engines, some type of lubricity additive is a good idea to keep the fuel pump from wearing out as well.

Definitely steam clean your tanks and lines if you know it is full of junk... ANY kind then use these two items .. owned a fleet of diesels before I retired and I can tell you I let the drivers pick their diesel treatment and after two hard winters in a row the only rigs that could run in the below zero cold were the ones running Howes diesel Treat and never injector problems ..the fleet went 100% Howes after that
I used a fleet contract fuel service but they guaranteed no algae which they did directly in their huge tanks with 55 gallon drums of Howes Algaecide that they once had in consumer size bottles but no longer ..
I would bet the "Farm Meaner Cleaner" has the algae treatment in.

just buy real diesel, absolutely no bio-diesel and you wont have the problem. you will need to ask for it at a fuel supplier, the stuff from gas station pumps all have the bio-diesel, no farmer in his right mind will buy the bio stuff due to them needing to store it for extended periods of time, i have 5 year old real diesel thats still good.
if you are ever being chased by a taxidermist, don't play dead
Our Ultra Low Sulphur Diesel is DRY. Our diesel standards are much lower in the US than in EU, and lots of systems are made in EU! Lubricity is what you need. Stanadyne Lubricity Formula at Tractor Supply.
A friend purchased a diesel Mercedes-Benz van for him and his wife to tour the US. It's one of the really tall ones that they can stand up in. I believe it is a 2019. It is not biodiesel compatible. They can't take it to some of the mid-western states since the only fuel available at the pump is biodiesel. They also have to plot their course to ensure they can fill will regular diesel.Originally Posted by Cast10
Additives may or may not work to run biodiesel in it but Mercedes-Benz's states no to any biodiesel period.

I once was able to get free stale aviation kerosine .....this was the very worst Ive ever had for fuel fungus ......and is the reason, I gather, that planes must be drained and refilled with fresh fuel every 30 days.....Anyhoo,a lot of people around the airport ran cars and trucks (like 8 ton trucks) on free aviation kero.......Potentially a massive penalty ,but as far as I know only bulk users have ever been caught by the Excise .
I've heard some guys add a tiny bit of gasoline to keep the algae from growing.
When I quit the refinery ,I took precautions while I still had my pump key ,and managed to get enough diesel to last 5 years .......knowing it would be stored for years ,I put a bottle of boat service biocide in every drum.........the last drop was as good as the first ,and I sure missed free fuel........everyone in the oil co used to get free fuel ,and just after I left the Feds cracked down on it,and the free fuel was cut off ......no excise paid,only to be used inside the refinery site by contractors.
I have tried but all diesel around here has some bio in it. The local bulk distributor carries it but won't sell in small quantities. I usually only keep 10-15 gallons on hand. That will do a lot of the work we do around our place. I just can't justify a bulk tank for 2 small tractors.

I’ve used additives in the Arctic to keep diesel from gelling and others in the tropics to keep down algae growth, but one of the best things you can do is add a Raycor type drainable filter.
People hook up oil tanks to oil burners with 3/8 copper.
The black goo will stopper it solid.
I used "DieselPep" and a handpump to push the crud back.
Then added a spin-on filter after the old "filter".
The cellulose filter is the water trap, and the spin-on catches fines.
Trouble with spinons, is a little water will plug them up,
but a cellulose filter will pass nice clean water.
Beware cleaning an old oil tank!
The black goo is plugging up the pin holes!
