Wouldn't a truck with external tanks be much more susceptible to algae than a bus with internal tanks? The sun beating on the tank will keep the fuel warmer, causing increase in growth. Not all algae require sunlight.

Algae needs nitrogen to grow where does it come from inside a fuel tank ? now a Fungus growth I can see

Snake oil, save yer ca$h.

As noted, 40 wt, low ash, CF2, which is an old rating, some may not print the rating on the bottle, even if it meets/exceeds the rating. New oils are al low ash, ash is bad for the DPF in new equipment.

Exception to every rule: anti-gel may be considered for real winter conditions.

If the fuel tank has developed growth, the fix is to have it cleaned properly. Killing bugs alone, then their residue/bodies plug the fuel filters. Over and over... destroying your reliability.

Happy coaching!

I try to put 16 oz of lucas when i fuel up.

Thanks luvrbus--that makes sense about the old injection system vs today's.
No Amsoil products chessie, mainly Lucas, Howes, Power Service, and FPPF is the algaecide people..

Snake oil salesman am I Warrior? lol... You know, I'm no mechanic, but I've learned a lot from my customers over the last 17 years managing a heavy duty truck/trailer parts store in western Okla. It seems not much of that is going to help me much with my 81 mc-9, which Ive had in my possession now roughly 72 hours.

I'm anxious to service it, it's been sitting for over a year and I was concerned, apparently needlessly, about the 1/4 tank of diesel I drove home on.
Thank you everyone for the input---cant wait to get started on this.
Until next time!!!

You know what they say about a dealer sampling their own product... LOL!

Someone has to take the others' ca$h, might as well be you?

With the billions of dollars of capital at stake, the engine manufacturers and the fuel and oil companies would not be leaving anything out, if it was going to help an engine improve its profit making abilities.

Best thing a bunut can do, is run the coach regularly. Sitting makes way more trouble than any other item of discussion.

Fill 'r up, and down the road!

Happy coaching!

Generally, its better to keep tank topped off to ward off condensation in fuel tank. Stanadyne used to or still does sell a biocide to kill the bacteria growth in fuel tanks. Many of the products sold today only remove moisture. Check label carefully. We had to add this in the 80's to the Olds diesels to stop the black slime growth on the in tank screens. The stuff worked well.

Well you guys were right about one thing..this ol 8v71 isnt picky about the fuel she burns..
Just changed fuel filters...black goo sitting at the mouth of the primary, still purring like a kitten...a large, loud kitten

Thats tar and bug guts from the diesel and the diesel eating away at the inside of old rubber hoses.

OKIE9ERS · June 22, 2018, 11:48:55 AM

I hate to think how long them filters been on there

Dave5Cs · June 22, 2018, 11:50:47 AM

Whats real fun is to take a chisel and make a hole in it then cut it open and see all the different crude inside it.

You can get this from fuel fillups that don't have a fuel contaminent prevention program.
Here is some info: https://www.bellperformance.com/bell-performs-blog/recognizing-diesel-fuel-algae

Fppf and Stabil, among others sell fuel treatment. Look for the term "biocide" on container. Stabil is available at tractor supply.
If the fuel treatment container doesn't have the term biocide, it is mainly used to remove moisture from fuel.
Biocide shouldn't be used regularily, but at least once or twice to kill the bacteria. Then you can use a fuel treatment as you see fit. Keeping fuel tank full will help to minimize moisture entering fuel due to condensation. Especially when not being used for long periods in warm to hot weather.
Biocide is available at most auto parts stores and Walmart, however it may need to be ordered in. I'd try Tractor Supply or Napa first. You can order from Amazon, but more expensive.

Thanks chessie, I actually keep several fppf products on the shelf..their biocide they call Killem...they also add lubricity to the fuel with all their products, something that has been removed with some of today's diesel, apparently..

But...

You have to get the resulting black trash out.

Depending on contamination, you could be changing fuel filters by the mile. Picture the surface area of the tank bottom, compared to the size of a fuel filter.

For the newbie, plugged fuel filters means engine doesn't run right, eventually won't run at all.

And when you think you have it cleaned up, the next washboard road you bounce over liberates another cloud of gook...

The boat peeps suck it up and get the tank cleaned, it is harder to pull to the side ofthe road in a boat...

Happy coaching!

Anybody with a 30 plus year coach should remove and clean their tanks. Most won't. I've done both our GMC's. The layer of crud will suprise you.
