I have used the Stanadyne Performance and have had good results. However, last winter, it gelled up in the bottle behind the back seat. The lows were about -30 at that time.
I know this might not be important to most but I have read a few times on this forum complaints about diesel fuel additive bottles and how they leak, stink and make a damn mess.
Anyhow, for what it is worth I put one of Schaeffer's new dieseltreat metal containers upside down in a bucket after using about 1/3 of the bottle during my last fill up. It's been 2 weeks and no leak.
again, not trying to start a DFA war (again) - just one of those little things to pass on.
be careful with that oil - adding oil to the fuel in not injector friendly.
I agree.. Why take a chance on messing up your injectors.. they are not cheap to replace.. I think it is better to use bio diesel as an additive.. a study shows bio diesel being the best of all the additives, by adding .6 gal per tank full. See the link in #3 post for the study results.

Spend your money on frequent oil changes and proper maintanence. Increased milage from additive products aren't guaranteed. I'd be willing to bet you see added milage from $10 worth of diesel. Sure you can make yourself feel good by putting something in your tank but in the end it's proper maintainence.

That study is definately a good one. Bio is great for lubricity, but can come with its own set of problem, and IMO if you're running a bio mix, you are still in need of an additive. The bio can have storability problems, and may start to go bad after 3-6 months. Bacteria can be a problem with bio. It's my understanding that Bio is also more prone to mixing with water. The correct additive can combat the problems associated with bio or a bio mix.
Edit: while an additive cannot guarantee you an increase in MPG, the protection that it gives your fuel system cannot be argued with. The new ULSD fuel is very hard on a fuel system, particularly the injectors. I'm very particular with taking care of my vehicles and you'll never find me filling up without an additive going in my fuel. It's just not worth it to me to run w/o an additive, knowing that the ULSD is damaging my new injectors.

I have heard that concerning the rubber parts in the fuel system like o-rings but nothing about the rest. AFAIK, ULSD is hard on the fuel system if it were raw but at the pump level it has additives already put in it to make it equal to the LSD we had before.
The ULSD is supposed to have additives in it to restore the lubricity. However, that is the responsibility of the local fuel jobber. Some will choose a good additive and put in the appropriate amount...others, who are more concerned with money will pick the cheapest additive they can find (whether or not it works) and just barely add enough to say they did it. It's the latter that I'm worried about. What's worse is I don't think there is any regulation surrounding the jobber using an additive to restore lubricity, other than they are told to. If there is, who's checking and what methods are being used to test the lubricity of fuel at the pump?
Maybe it's overkill, but I'm not leaving the potential for damage to a $3K set of injectors in the hands of local fuel jobbers. My .02.
We may be talking about the same thing, just using different terms. When I say local jobber, I'm thinking where the fuel is distributed to each individual station...where the tankers fill up. To me, it's local since a lot of our stations get their fuel from huge tanks just about 10 miles south of town.
Is this what you're saying by terminal or are you saying each individual station is responsible for it?
Either way, I guess it doesn't matter to me. It's up to a human to make sure the additive is in the fuel and I'd prefer that human be myself to eliminate any chance of errors.
I was talking to the owner of a station I buy fuel from and asked what brand of fuel he sold and stated I got better fuel milage on the fuel I bought from him
he mentioned several places he purchase from and said he had additives put into the fuel when he ordered it
