Looking to protect against low sulfur, not concerned about algae...Valvatec?

Exactly. Modern fuels already have additives to counter any "lost" lubricity from low sulfur. Actually, for instance my Detroit 8v92ti engines like low sulfur, the only spec DD has is against too much sulfur.

Valvetech is great, but fresh fuel and regular running is better.
 
The power service has greatly reduced the asphaltines I used to find in my Raycor 900 filters.

I am now a believer.

I have 5.9 cummins in a few service trucks, ever since low sulfur came out we have been burning injectors. Started adding lubricating additive and problem went away. Bosch (fuel pump manufacture) recommends a replacement supplement for lubricantion.
 
Bob I have been told it's not the additives it's filtering the fuel.
I'm new to this but I have old school mechanical diesels.

Dave, excellent post! Thanks very much.
Billy, boat will run often, have racors and secondary filters. You never know what you are pulling out of the service station fuel pump, have replaced injectors and injector pumps before due to ulsf. Sucks. Off road fuel is supposed to be low sulfur or better and died red. I know a fuel distributor whom I can't name obviously, admits sometimes the same fuel goes to multiple places and is labeled accordingly. What's another ten bucks when you are doing thousand dollar fill ups.
 
If anyone has ever seen a recommendation for additives from an engine maker please post a link.
RWS you may have dimly cleaned your tanks

Inexpensive and a good insurance policy for pre-ULSD manufactured diesels.

Except Detroits. My service manual edition came out well after ULSD. Again Detroit stated a bias in their very detailed fuel specs towards lower sulfur, not higher. In fact above a certain level, they specify more frequent oil change and maintenance intervals. They do not recommend any additives at all, unless the boat is going to be sitting in storage for a long time, then something like BioBor.

As someone else mentioned, check the engine manufacturer. There is so much urban legend around additives.

Thanks for the link . Hell has indeed frozen. A new profit center for them. Do they require any additives under warranty?

Yep, hell has frozen....don't know about the warranty question as my Cummins was built in 1998.
 
Some people run a small amount of two stroke (TCW) oil in their diesels, claim it improves fuel mileage and heads off problems due to the alleged lack of lubricity in low sulfur diesel. One thing about it, it shouldn't do any harm, diesel engines will burn the oil without complaint. I recently put some Power Service in my old Fordson tractor with a 3 cylinder Perkins and fancy that it starts and runs better, not that it was running so badly. We use an additive in the tanks for our old Perkins in the Mainship 34 to head off algae growth, can't remember what it is.

=========================================

Bruce,

The fact is that since I began using the Power Service additive product there are far less accumulations of asphaltines in the bottoms of my Raycor 900's.

Before the Power Service additive was used, changing the fuel filters required a mechanical cleaning of the brass drain petcocks.

Now I simply blow them out with compressed air!

Clean !!!!!

While not a purely scientific, controlled test, the results are good enough for me !

I LOVE my mechanical diesels !
