additive to diesel fuel for winter?

[terraplane]

When I winterized my gas driven boats i added Stabil to a full tank. My R 25 is now on the hard, winterized all systems, and it has a full tank of diesel..no additive. Should something be added for the winter?

Diesel will definitely grow critters if it sits too long.

A highly respected product in the diesel truck market, is Stanadyne. I've been using it for years in my PowerStroke - can't imagine why it wouldn't be a good idea to treat your Ranger with it as well.

Per their site, it's fine with ULSD engines.

Here in the Pacific Northwest most of our diesel guys swear by this product called Lubrication Engineers. It comes out of Texas and Im sure you can google it to find it. Just like Da Nag was saying it is a good idea to add something in the tank.

Is this recommended for boats staying in the water through the winter? We'll still be boating as weather allows.

 

[Andrew Custis]

Some reccomend to use it all the time. Someone like yourself Bruce that uses his boat frequently throughout the winter I wouldn't worry about. Its when the same fuel sits for periods of time you have to worry about this.

That's always struck me as very strange. Stuff just shouldn't grow in fuel. What is it doing in there? Where did it come from? What does it eat?

The old marine standby for diesel is Biobor .http://www.conntect.com/fueladditives/biobor/ We also have a product called PRID that I use in my truck that seems to keep things clean . http://www.priproducts.com/
Its the fungus among us .

On the Mis Dee with the 125 Yanmar. I was warned by either the owners manual or the Yanmar dealer to not add any fuel additives to the fuel. My old Chris with 2 stroke detroits, I used bioguard when storing the boat. 5gal can from Napa, was expensive but necessary. I would check with manufactures before adding anything to the new diesels. Even the new diesel pickups that use 15 ppm Low sulpher ccould be a problem with some addatives.
I really don't know, got to check with Cummins before I would add anything.

I had dual Racor 1000,S in the Chris and have seen the filtered out alge so thick you could not see through it. On a friend Defever the fuel line plugged solid with the growth. It came out like a long black worm out of his fuel line. Thanks to Racor it did not get to his engine. Warm climate areas gets the stuff growing much quicker.

I spoke with Randy Day at Cummins NW about this very subject back in May and he said that they recomend using Valve-Tech brand. I have purchased it at West Marine.

When I lived In Chicago, we used "Valvtect" in Diesel boat fuel tanks. I think that's how it's spelled. Anyway, It's an all in one additive mixed for "Marine" diesels to last clear thru a year of winter. It might be worth checking into. BB+
