Water in the fuel tank getting stirred up when you gas up or water in the gas station tank?

[TimW]

Ah, for diesels you want BK 245 Fuel system cleaner for Diesels.  $25 on Amazon.

Did you mean BG 245?  https://www.bgprod.com/catalog/diesel-fuel-system/bg-245-premium-diesel-fuel-system-cleaner/

[gspren]

I recommend a can of BG 44K.  The stuff is amazing at dissolving engine deposits.  It will clean your system better than any fuel system cleaner I know of.

Pour in half a can of seafoam, she purrs like a kitten. Top off the gas tank after it's down, random misfire codes.

Grrrrrrrr?!?!

Do you always fuel up at the same place, if so try somewhere else. Maybe try a tank of premium and if that works try some mid grade, sounds like poopy fuel.

[rusticretreater]

Yes BG 245. Typo

It's usually the same brand (local convenience chain), but different stores w/in the brand. I was reading a few things about that, suggested a zero-alcohol high-octane fill-up (as if it's not expensive enough!) I usually get the 97-octane no-alcohol fuel for my small engine machines (including my sawmill), thinking of putting 5-gallons in the tank to see if it helps (sans seafoam).
It ran good yesterday, after re-setting the ECM, but there's some seafoam in the tank, so, not sure it's fixed. I plan to do some running this morning, will add fuel to the tank and see if the misfires come back. Want to check the local shop for that BG42 or some Redline (interesting read on the ingredients here: https://ricksfreeautorepairadvice.com/the-best-fuel-injector-cleaner-and-fuel-system-cleaners/ )

I had a Colorado PU I bought used and that had some rough running issues.
It would stall at stop signs sometimes and run rough at times.
I put some super gas in it and it helped out some.
I always got my gas at the same place.
They close the place to count money around 1, when I would go on lunch.
So I got some super from another gas station. That truck ran great!!!
Then I went back to the same place I always get gas.
Started to run rough again.
Then I went back to the other gas station.  Ran great again.
I did this 4-5 times and every time I went to the other gas station to get gas it would run great.
I went to the other place to get my gas.
Just so you know this took a while too, I only drove that truck to work, about 50 miles to work each week.
I always thought all gas was just about the same.

[NewYankeeSawmill]

Thanks @thecfarm . About the only thing I haven't tried yet is dropping the tank, dumping it out, and putting a fresh fuel pump in (only 30 bucks!)

[barbender]

Ray you sound like a quick learner in this case😁

[aigheadish]

I went out today and got the starter in the backhoe and she fired right up! Picked up a big fuel tank the neighbor gave me, and scooped out a few stumps! Good stuff! 

[aigheadish]

Does anyone know if it's standard to put de-gell-er in pump diesel? I always add some come winter time but it's coming up on time to buy another bottle of it. Maybe I don't need it? My FIL is giving me a diesel tank, 150 gallon I think, and I'm hoping to get farm-use fuel to put in it.

[Resonator]

In winter, northern states treat the diesel at the pump, southern states not so much. When in doubt, put in some anti-gel to treat it (can't over do it). Also good to keep the tank full, then there's no air to condense moisture inside the tank.

[RetiredTech]

I've never used it down here, but I probably would If I were further north like you. I have 150gal. above ground tank myself. I haven't been able to find anyone to deliver diesel to it. I think the minimum delivery size here is 500 gallons. It's kind of a pain, but I use one of those big metal framed plastic totes to keep it filled. I have a 12volt pump on a pipe that I use to transfer it from tote to the tank. The good thing is I only have to do it a couple times a year and I always have diesel available.

[Magicman]

Like RetiredTech above, my Diesel fuel is not gonna gel due to weather, but I still add an ounce of Stanadyne and a teaspoon of PS BioKleen per 5 gallons. 

Whether needed or not, I replace both the primary and secondary fuel filters with every oil change. 

[aigheadish]

I haven't called about getting the tank filled yet to see if it's possible, but i think I'm close enough to civilization that I don't think it'll be an issue. 150 gallon tank, if that's what it is will last me a long time. 

[Tom K]

I don't us any additives in my bulk diesel tank, but it also gets used & refilled once or twice a year. Typically gelling isn't an issue where we are. If it's going to take you years to use 150 gallon I would maybe only fill it half way, and use a stabilizer.

[SawyerTed]

Watch out for condensation in those large tanks that aren't full.   Just be vigilant about it.  

[Magicman]

I only have a 50 gallon transfer tank at the farm, but I try to keep it topped off with my 5 gallon sawmill jugs. 

I am using the additives because I had a failed engine probably due to bad "off road" Diesel.  Other users also had problems that were so bad that the station discontinued keeping and selling "off road".  I now only use highway pump Diesel.

TimW questioned my recipe for the above treatment items.  The Stanadyne is simple to follow the mixing ratio.  The PS BioKleen not so simple.  The bottle states one ounce to shock treat 20 gallons and one ounce for maintenance treating 55 gallons.  My 5 gallon jugs rarely require over 4 gallons to fill because they are rarely empty and I never fill to the line.  It takes 6 teaspoons to equal an ounce so one teaspoon per 4-5 gallons is close enough for me.

[doc henderson]

Lynn, I am sure you know this but the maintenance ration for your diesel is about half a teaspoon per 5 gallons, or 2.7 cc.  better safe than sorry I guess.  

[Magicman]

Yup, I am not using a measuring teaspoon which is also not filled level anyway.

[doc henderson]

quarter glug!

[aigheadish]

Thanks for the notes guys. I've used a neighbors off-road diesel before without any issues and I don't think he's the type to do much tank maintaining, though I certainly will, to some extent. 

[doc henderson]

Does your neighbor know you are using his fuel?  

[aigheadish]

Haha! Yeah, I was doing work for him and would take a fill-up in leau of payment. 

[RetiredTech]

I set mine up with a fine wire strainer (I think it was stainless steel) inside the tank a few inches off the bottom. That keeps any big stuff and any condensation out of the pump. Then there's a regular moisture removing fuel filter on the output of the pump. I put a spring loaded vent cap on the top. That probably helps some with the condensation. I've never gotten much out of the bottom of the tank. The only maintenance I do is change the filter whenever needed and check for water at the drain valve once a year or so. I run off road diesel in my tractor, sawmill and generator and have never had a problem with the fuel. There are three stations 30-45 minutes away that have pumps. I just have to take a mourning to go get it.

[Stephen1]

I hear ya @SwampDonkey ! 
I swore off Fords after my BIL (a retired Ford truck tech) said he wouldn't buy any F-series truck made in the last 20 years. My cars have all been Honda or Toy, they run like champs. Have you seen the prices on used Tundra's?!?!?    Why I bought the Dodge....

and now you wish for the used Toyota? 
I just buy them brand new and drive them for 10-15 years. I am on my last one I hope. 2022, and they are going to put in a new engine for me soon, so I figure my last one for sure. I might end up with 100k on it before they finally get around to putting the new engine in.
