Do you have a picture or link to the pump dispenser you have?

D_R_C Buying in larger containers and having smaller bottles to put in your desired amount will save you $$$.
With most additives you usually can double the dose, a little more will NOT cause issues.
There are several good fuel additives available, everyone has their own favorite.
Diesel Kleen and LUCAS are my favorites buying in the gallons, on my mix costs me about $1.25 per tank, Iím double dosing DK, because our fuel quality is questionable.

That was a fun surprise to find when opening up the canopy to put groceries in it. The smell isnít the worst thing but itís not pleasant.

Any recommendations on better containers once opened a larger jug? How are you guys measuring the amount as well? Iím not trying to run my truck down too far. Iím trying to only use Costco Top Tier Diesel (5% bio) and itís 30 min away so I try to plan ahead and fill up before I get down to 1/4 tank. I canít really add the full small 8oz bottle that treats 30 gallons when Iím usually only putting 20-24 gallons in at a time. I donít think adding the full dose to a smaller tank and having it be higher than recommend concentration is a good idea is it? So I havenít bothered to buy the small containers since I wonít be just dumping a whole one in anyway.
Stanadyne is a great product. I keep a small bucket in the back and keep my additives and extra oil in there so it doesn't spill. A little over the recommended dosage is not going to hurt anything and could help with what it is there for.

What do you think?anyone use product and have real world experience?
The Hot Shot oil additive was designed for folks who own an ill fated Furd PS with the HPOP injector system. I doubt if there's any advantage to using it in a Duramax. However, the Hot Shot's Secret Extreme Diesel is a fuel additive. I tried it in my LLY, injectors were getting intermittently knocky so I figured I would try it before replacing them. So far, it has quieted them down so maybe i can hold off replacing the injectors, at least for now. Truck has noticebly more power, runs cooler, quieter, better MPG after two tanks. Mfgr only recommends using it once every 6 months.....

rock4xfab I used XDP in the summer and XDP Polar D in the winter since I bought the truck. Until last winter I pulled into the fuel station reached for the polar D and it was as thick as maple syrup and would not pour into the funnel. So onto the next, I have nto quite decided what to use in the Winter. I run #2 winterized from Kwik Trip and the best my truck ever runs is on whoever supplies Meijer with there fuel.
