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 just wish we got B5 out of the pump like Pennsylvania does.
Hey Aaron- I am also new to diesel. You mentioned that PA has B5... I did see that when I fill up too. Thought that seemed ok... should have researched diesel up front.

Can you tell me why you use all these additives? Is that because of the bio-diesel mix or should I look at an additive for ANY diesel I use?

BTW - I really wish that there was a website for which stations offer what type of diesel... not available anywhere from what I can find. I've been using Sunoco locally because it's the main refinery locally that most stations get their fuel from (like the popular WAWA up here).

Anyways, thanks for any pointers.

Wow - what a few days of research will do...

I am new to the TDI & Diesel... so taking all this in. I live in PA and am hoping my Biodiesel blend the state is mandating (currently a B5 I think) will be helpful. I've seen people criticise the variety of grades... and cetane - geez. Guess I have to go into the stations and ask them for their print outs.

I did find this site and this it's great for a novice like me.
Lubricity Additive Study Results but that was 4 years ago... maybe it's changed since.

I wanted to see if someone has a one page overview for proper Diesel usage and what they SHOULD know before putting it in their tank ... any ideas?

I've found some of these pointers helpful to be mindful of:
  • Cetane Levels
  • % of Bio Important
  • Additive (vary winter one... summer one)
  • Sock to place over the pump - filter crap before going into tank
  • Only fill at high volume stations
  • Keep Receipts (just in case)

What I am really trying to understand is what we should use as a baseline for proper Diesel formulations in the US too. Of course, there are no standards right now and I think that's why I personally am in need of this cheat sheet to reference. Would be great to also get us all pushing government toward a baseline too.

Any help is appreciated!
