I bought my boat with full tanks filled around Sept. The boat just went in the water. A buddy I f mine who runs a truck said no problem. My diesel mechanic at work said dump it. The cummings dealer I buy my trucks from said 'it depends' on what the fuel is.....

Anyone with any advice/experience?
 
I would say it is probably fine. I fill my tanks at the end of the season to reduce condensation in the tanks. I do also add stabilizer, but...

Just keep an eye on the racors, you'll know pretty quickly if you have a problem. But again, unless there was something going on in the tanks beforehand, I think you'll be fine.

I'm surprised about the response you got from your mechanic. The situation you're in is what 90%+ of seasonal boaters are dealing with. You said that the tanks were filled in Sep. that's great. Now all you have to do is basic spring fuel management maintenance (this applies to mains and the generator), which is:
1. Add "Power Service Diesel 9-1-1" to each tank.
2. Change Racors on the engines and generator.
3. Change fuel filters on the engines and generator.

As an extra precaution, since you don't know if any additives were added, I would add the following as well:

A. biocide (http://www.powerservice.com/bk/)
B. Power Service Diesel Klean (gray bottle "Diesel Kleen® +Cetane Boost®"
C. STANADYNE LUBRICITY FORMULA

I use the "A/B/C" additives on every fuel up and only use 911 one time the boat goes back in water and the fuel sits from previous fall.

Go boating and enjoy burning that fuel. As you start your first trip go slow and catch few small wakes abeam to get the boat rocking side to side just enough to get that stuff mixed well in the fuel. It's not easy with full tanks, but any effort you put in to that will only help.

I filled my boat early october (pre sandy). Did all necessary maintenance / addatives as above. Ran the boat 2 weeks ago for 75 miles (50 of them 6' sustained in ocean) and she ran perfectly.
 
Thanks as always to the CSR members for helping out. I called the marina to get an idea when the boat was filled -some time in '11! I knew the boat was hardly used but.... as for my mechanic at work and in his defense - he at least did the research and found that the EPA reg claims diesel breaks down at 3 months! Thats what happens when you count on the gov't....

Ran her a little over an hour and saw 39+ SOG at WOT so im guessing im ok. Filters etc were down and service mech said fuel was ok.

Alex- That sounds like a lot of additives! May I ask why you use both the Stanadyne and Power Service Diesel Klean?
Looking at the products side by side they appear very similar? I'm rather new to the diesel world so am not trying to
second guess your usage, mainly would like more information.
Thank you!

Let me start by saying that all I'm doing is following Frank W advice. When I got the boat and started learning about diesels Frank explained that fuel management is one of the most important items. Keep the fuel clean and those engines will just keep going. All those components I used based on his suggestion. It sounds like a lot, it sounds like an overkill, but i have my routine worked out 1 bottle of Diesel Kleen and Sanadyne per fill-up and I'm good to go. When buying by case they're not that expensive. If you spend $800-$1000 per fill what's another $30 to give you comfort level that your fuel will be clean and engines will get extra lubricant?

Here's why both:

Power Service Diesel Klean (gray bottle "Diesel Kleen® +Cetane Boost®"): advanced diesel engine performance improver that cleans injectors, boosts cetane and lubricates fuel injection components.

STANADYNE LUBRICITY FORMULA:
Cleans and protects injectors and all fuel systems components. Demulsifies water for filter/separator efficiency. Fights formation of corrosion and rust. Keeps fuel fresher.


Biocide - you only need a tiny bit. It comes in a small bottle and it last for few fill ups.

911 - I only use once a year when the boat is splashed. This is to provide a bit extra boost for fighting moisture and anything else that developed over the winter. It's not necessary since I know that my fuel was always treated, but an extra "insurance".

The reason I recommend both Diesel Kleen and Stanadyne Lubricity additive is because I don't know and cannot find out from Power Service (I even met with their regional sales people) just what Diesel Kleen does to the fuel's lubricity. They will not or have not tested and do not know just how much their product enhances lubricity, just that it does.

Most diesel injection systems are made by either Bosch or Stanadyne and Stanadyne makes the additive so their equipment can safely burn ULSD. They should know what is needed and they don't expect you to accept their word for it....they will provide data sheets covering lubricity improvement with the additive.

The other factor is that you cannot over treat with Diesel Kleen so while it might look like double dosing, all you are really doing is ensuring against an early pump/injector failure when you use both additives.

I should ad that we are now (about 5 years after its implementation) some Cummins pump failures in our area due to inadequate lubrication in the fuel. This tends to make the $6.50/ bottle for the Stanadyne additive look real cheap.

THere is probably more reading on this subject than you can stomach, but go to the CSR home page, then go about 1/2 way down to the articles and one on diesel system management is about the 3rd one down.

Thanks for the follow-up Alex and Frank. I will continue to read and learn as I go. Presently I am just using the Stanadyne Lubricity. I will need to look for a supplier of the Diesel Kleen.
Cheers!

If you are talking about the winter formula in the white bottle, Yes, it won’t hurt anything but unless you have a bunch of it laying around, just buy the supplement in the gray bottle. I have never been in a Walmart that didn’t have it.
