Diesel Addatives?

Say, I always kept a small box with several screw top jars of addative in it I'd use every fill up. 2 oz. summer and 4 in winter. Anybody have advice or suggestions regarding this practice?

I've used Power Service in my diesel vehicles since '01 when my NEW (2500 miles) F350 gelled up. They towed it to a heated garage at a truck stop, let it warm up and put in Power Service in the tank. THe guy there told me that if I'd keep power service in the fuel it would never gel up on me again. It never did, neither did the other diesel's I've had since. Have it in the '12 Jetta right now...
I have to say that gelling is not something that you should ever have to worry about if you are buying proper winterized diesel. I have never run additives in my TDI's and made it through a very hard winter last year with many 0F and lower nights and no problems. Car was parked out side all winter.

The only times i have heard of gelling is when people buy diesel in a warm climate that doesn't sell winterized fuel and then drive north of to high elevations and endd up below freezing with the fuel.
That's what happened to me back in '01....Note however that while "most" stations in the northland will run blended fuel, some places, especially in the central part of the country (north to south) MAY not have it. I run PS just to be "sure"...Also, it's a good lubricant for the injection system, so no harm if it's not needed and no problem if it is....
Are additives necessary in warm weather climates? This is all new to me. We currently have a 2000 Golf TDI with 325,000 miles on it, and I never added anything to the fuel. And the engine has never given us trouble (everything else around the engine has). Now, we also have a brand new 2012 JSW TDI, 2,600 miles, and I have added nothing to it.

FYI - we live in SE Louisiana, and I have a daily commute of 130 miles a day, 80% on open interstate, 15% in traffic on the interstate, 5% city driving... give or take...
You shouldn't need additives for gelling where you live, UNLESS you fill up locally and then head north into seriously cold country during the winter...THEN you might encounter gelling as your local fuel most likely is not winter blend. For other purposes, you may wish to use an additive for increased lubricity and/or increased cetane (to diesel what octane is to gas). Higher cetane will typically improve combustion some and "may" increase your fuel economy a tad....
