Questions, Use of Fuel Additives

[tonto]

So I was browsing the Diesel Tech Society page, reading about the use of fuel additives and I ran across this:

The cetane level, a measurement of the ignition quality of diesel fuel is an important part of fuel quality. Most modern engines run best with a fuel cetane rating of 45 to 50. Use a cetane booster and performance improver if you know or suspect your fuel does not meet those numbers. Engines with COOLED EGR SYSTEMS will benefit from the lower soot levels influenced by higher cetane numbers.

Low and Ultra-Low Sulfur fuels already contain additives to retain the necessary lubricity qualities needed in diesel fuel. Adding excessive amounts of lubricity improvers can lead to gumming of internal injector components resulting in poor performance

Being relatively new to the diesel world, I walked in with the assumption to "always use brand x additive" because so-and-so uses it every time they fill up. I understand there are a few different types of fuel additives, but I'm wondering if overuse of any type of additive will lead to problems in the injector components? I use Amsoil Performance Additive usually every time I fill up, had been using Amsoil cetane boost for some fillups at random. I guess my question is is there a concrete system to use these additives to their best potential? thanks for the help, Ill have a million more questions for you all later

I use the Power Service additive. Grey bottle in summer and white bottle in winter. I follow the label for how much to add, but I don't think that adding to much will hurt the engine any, as long as your not dumping bottles in at a time.

I think centane boost should be used on each fillup because the fuel we get is low to start with, i use the Ford stuff get it by the case but i will be getting it in the gallon cans 2 gallon cost less than a case plus you get about a bottle free if you go by the ozs it helps keep the turbo and egr valve clean and if you drive it like you stole it once a week that helps.

I use powerservice white every 3 -5 tanks.

I use XDP's Power Plus bottle. It's very affordable and one bottle will last a good while.

Also depends on how crappy your fuel is to start with. I've been trying to get premium #2 diesel instead of plan #2 here in town. Runs better with premiun for sure.

how can you see if it is better or not?
