Lets see why use an additve well for one mpg is no concern of mine and not the reason i use the additve i use the additive to keep everything lubed instead of relying on the govt to decide whats right for my truck i also use it to keep the injectors clean and also the truck runs better with it so monkey see monkey do is funny but i guess its the same for all the add ons done to my truck and yours so if i read your post correct its just like the old saying about mustangs (you have a mustang me too)you did things to your truck me too

 

The govt is saying that it must have a minimum amount of lubricity to keep things as they were instead of wearing out all the IPs in the trucks. As I have said before, if there is proof that it does anything good besides speculation, guesses and SWAGs, I'd be all ready to see it. It's very simple. If the manufacturers of those snake oils can show me that an average injector lasts 5000 cycles WITHOUT and 6000 cycles WITH, we have the basis for a discussion. Where is that data?

How do you know it keeps the injectors clean? Again, where is the data?

Runs better. What is the quantifiable definition of that?

Monkey see, Monkey do is in reference to your comment of "Since i was young and my father taught me to always use an additive i have stuck to it religously". Things may have changed since then. It is always prudent to analyze why something is being done instead of relying on "I was brought up this way.". Computers used to be about that way. They do what they are programmed to do. We are trying to make them do things that they were not programmed to do. We are trying to get them to think for themselves. Shouldn't we, the humans, be doing that too instead of "This is what I was told so no thinking is required. Just repeat."?

The difference is that I put add ons because there are quantifiable results. Put X on and the EGT drops or the trans temp drops or the boost goes up, etc, etc. Those are quantifiable results. I don't put stuff on the car just because. If I don't see quantifiable results, that part comes off and gets sent back.

PS. Punctuation makes reading easier and the meaning clearer.

 

Yes i have been wondering as i have never tryed any additive. Later this year i will be doing alot of repeat driving when i can try some and see if i notice any imporvments. Joe

 

Wonder about this. There are tons of OTR trucks out there that are diesel. If ULSD were that bad, won't they be lined up at the diesel shops for repair? Lets forget about them for a bit. Lets talk of the light trucks. Why aren't there lines of light trucks with diesel engines at the repair shop if ULSD was that bad?

 

This is an interesting discussion. I am guessing that only time will tell the answer. I am not so worried about the short term effects of it. I am thinking more about the long term effects. If the decrease in lubricity changes parts from a 300,000 mile life expectancy to a 250,000 mile expectancy, that is a fairly large difference. Additionally we as end users would not notice this until many years down the road. This is precisely what my father and I are trying to avoid.

 

But if you spend say $10000 in getting that 50K, when a new motor costs say $5K (just numbers we are pulling out), does it make financial sense?

 

Most of the common additives are fairly cheap in the big picture.

 

Depends on where you break down.
