Fuel Additives
 

Down here in South Texas, some call it Central Texas :DD: I'm not too worried about fuel gelling. But, I am wondering if fuel additives are necessary.

I read alot of you guys religiously add stuff to the fuel. Does it really do anything? Should I or should I not add fuel additives? Why or why not? What do you add and what does it do?

I have an 07 Cummins 5.9

Thanks
Randy

Randy.....I agree where you are gelling is a non-issue however you need to address the fuel lubricity......the new ULSD is dry as when they removed the sulfer alot of the lubricating properties went with it................yer CP3 dont like no dry fuel and will suffer gradually till one day it will give up the goast.............the fuel suppliers are supposed to be adding a additive package b4 it goes to the end user (YOU AND ME) but it dont always happen....been there done that myself as I delivered transport fuel myself for a couple years.........anyway to answer yer question I would add some 2 stroke oil in every tank to get the lubricity back..................2 stroke oil is ashless and is ment to be burnt.

I read alot where peeps put used motor oil, new motor oil, ATF and all kinna crap in there tanks..............each to his own but I myself dont want that in my tank

Like I said each to his own........and I dont wanna argue about it either

A good additive is probably cheap insurance. Lubicates the pump, stabilizes fuel, improves fuel economy, improve emissions, etc. There are many...I can point to one:w2:

here is some good info from an independent study

By the chart, I think it tells me that I want the additives in the green and blue bands to address the lubricity issues.

What about other fuel contaminants or irregularities? Water, algae, bacteria, cetane ratings... anything else that needs to be adjusted or corrected with additives.

I've noticed that I've had a bad tank on occassion, a little rougher idle and some white smoke at idle. Everytime I turn around I am reading that DC rejects another warranty job due to bad fuel. I don't want to be a statistic.

:w2:

A litttle two stroke sure keeps both mine happy, been running it for almost two years now, no issues what so ever.

I run Power Service in the silver bottle at every fill up. I used to run 16oz of 2 stroke oil too, but I got tired of buying it.

By the chart, it looks like the best for lubricity is a splash of biodiesel.

solarwarp,

Being you have a 2007 I would say up to 5% Bio is the best and if you just want a quick clean up of your injector then use some of Heaths stuff. If your in a hurry then Lucas has worked very well in my truck. I never have had good luck with 2 cycle oil so I can't recommend using it at all thou I hear it works OK in the older engines.

JMHO

I can just remember my old Yamaha... I don't want my Cummins to start sounding like that.

I guess there really isn't any overwhelming recommendation to treat the fuel except for lubricity, which a splash of biodiesel will take care of.

I use the Amsoil every tank in both my Cummins trucks.

I just got home......towed my buddys PSD to my heated garage for the night..............damn kid had no additive and it was -8 last night............he will be good to go in the mornin

:ph:

need winter formula :argh:

too bad it never gets that cold :)

Wow, Whit. You come up with some good avatars, but that one is ugly!!

hahaha - that is for sure!


and poor kid -- does he drive diesel's much? hrmmm


and on topic of this thread, I would never add 2stroke oil to my tank. It wasn't designed for my engine and just because my engine will burn it doesn't mean its okay. I just add diesel kleen or a similar product and it works wonders.

my buddy got his ol wreck PSD goin.....I left early this mornin and when I returned I had my garage back

What? all it needed was a nice warm place to sleep for the night?

ya..............I am assuming he fired it up and got the additive circulating

All I can say is I did see a 1mpg increase when I started using 2cycle in my diesel. But I think lately they must be selling us some crap diesel fuel at the station cause I have seen about a 1-1.5 mpg drop since mid October. I am not the only person to notice it either, so it isnt all in my head...........:sos:

During the winter they switch to a different blend up North.

you guys are funny :wack: -- any diesel that has the fuel gel won't start until its warmed up and flowing again :2:

Thats what I told Mac the PSD dude.......he wanted me to come over there and jump start him and get it goin since it was gelled up..............................5 minutes later it was in the heated garage..........I aint messin with no gelled up shet

Hey Guys - Solarwarp has a 2007 CTD and I believe that model year is specifically designed to run on ULSD. His truck has a lot of emission control devices and I'm not sure that 2 cycle oil would be appropriate - it might mess up something that could be very expensive to fix. I'm not an expert - just done a lot of reading on fuel additives on various websites. I would consider some of the other more conventional additives, i.e. Stanadyne Lubricity formula; Amsoil Diesel Concentrate; Schaffer Diesel Treat, etc.

2-stroke oil is fine to run in the newer diesels. The DPF emissions systems only purpose is to remove NoX from the atmosphere and doesn't care what creates it. A diesel engine will burn just about anything you put in it. :up:

BTW- look at the chart in post #4 and see what was ranked #7 in the test.

:ph: Alright smarty. Trying to get someone killed? :ha:

Here is the original study done by Arlen Spicer. Thought I would post this to make sure he gets credit for his hard work. :up:

Ive been using the supertech 2stroke oil for a couple mounths now and no problems. isnt it funny how the best fuel is also the best lubracaint. LoL

I haven't added a fuel additive to my truck since I bought it in 04. I MIGHT order up some opti lube to try.

Now I'll have to get rid of the copy I got from somewhere els , I like have the original & the folks that did it .
Thanks John

FYI, my truck is a 2007 w/5.9L, the 2007.5 is when Dodge came out with the 6.7L "ULSD only" engine.

Unless I'm missing something... Without any specific fuel problem I am trying to mitigate, I think that I'll just splash some B100 in the tank, just to increase or add the lubricity back. (It ranks at the highest for lubricity anyways and costs 25 cents less per gallon.)

Bingo we have a winner

absolutly...............50;1 ratio of bio will give ya a 415 lubricity rating..............life dont get no better than that

now keep in mind this does absolutly nothing for diesel fuel gel point.....it actually make sit worse so ifin yer in a cold climate you better run an additive to lower the pour point

I would love to run B-20 year round but there is NOWHERE for me to buy it :argh:

We have B20 at 4 stations that I know of and a plant that makes B100. Alamo BioDiesel

I don't worry about it getting that cold too often in South Texas. :yeah:
