Thanks for your opinions . Oh bye the way I have a 2004 F250 6.0 . Mine has been great!

Diesel Keen will do all you ask. :)

Since I own several VW common rail diesel TDI's, where moisture in your fuel in bad juju for the whole fuel system, I add Power Service Fuel Supplement White bottle year round, to keep my fuel dry. I rarely, if parking overnight, let my fuel tank get below 1/2 a tank, to prevent condensation forming in the fuel tank and getting water in the fuel, since with rise and fall of temperature, the fuel tank breathes moist air in.

Also, every year, without fail, with the first frost of the year, I R&R my fuel filter, and before doing so, I double dose with Power Service white and run the fuel tank almost empty, do the fuel filter change, then top off the tank with another double dose of Power Service white bottle.

Take the moisture out of your fuel system, every fall, completely, and you'll never freeze up your fuel filter with water in the system, come every first couple of frosts.

I used to drive a truck, a Mack CH with 500HP. We didn't use any additive. I currently have 180,000 miles on my '05 Duramax. The engine has never given any trouble and I've never used an additive. I used to own an '07 Duramax. I had no trouble in nearly 40,000 miles with no additive.
I don't see the need to spend the extra money just to burn it out the tailpipe.

I use Howe's Diesel Treatment

Add some biodiesel.

My book says not needed so I don't. So far so good in 10+ years and 162+k and counting. JME.

I use Diesel Keen in the winter as my truck sits for weeks without being used. Summer nothing.

Sorry double post.

Trouble maker! You opened a can of worms with this...most of the answers you get will be preference based on nothing but opinion. Good luck. The folks that make it won't give you straight answers, and the last study done (Spicer) is getting old.

FWIW...you probably are better off with the right additive. As best as I can determine, the Bosch injectors are designed for european spec fuel...not the US spec...which has less lubrication. Do your research and then feel your way through....best you're gonna do.

The biggest no-no is alcohol based fuel additives and so called emulsifiers.

If it helps, I used Stanadyne performance formula for years, but just started using Opti-lube summer +. Stanadyne was fine but a little light in the lubricity department. Not sure about Opti lube summer plus...hoping for a new study.
