i did a search and found a hundred threads on additives and none was conclusive and most related to engines other than ours (6.7L)

is there a consensus on (i) should an additive be used and (ii) if yes, which one

i ask specifically for the 6.7L engine only

thanks!!

 

I think most people will say yes to #1.

#2, I don't think you wil get a consensus....

I used stanadyne performance formula since the truck was new.
I switched to opti lube XPD a couple of months ago.
I notice no difference.

I think I will switch back to stanadyne mainly because the opti lube XPD they say to use twice as much in the winter.... Or maybe use XPD in the summer and stanadyne in the winter. We have had a couple of cold winters and I had no issues with the stanadyne.

Thanks

 

PM-22A in the summer and PM-23A in the winter for me.

Not %100 sure I have to but it makes me feel better..................

 

what about PS Diesel Kleen?

i have used it because it is found almost everywhere.

helps with centane and lubricity. maybe not quite as much lubricity help as others but....

if its not enough than i may have to look around for other options.

 

PM-22A for summer.

PM-23A for winter.

 

I believe all the power service products contain Emulsifiers. This is a HUGE no-no for the 6.7 engine.

You should stay away from ANY additive that contain Emulsifiers!

 

IIRC, I think Tom (Crazy001) contacted them and determined the PS Diesel Kleen does not contain emulsifiers and is good to go for the 6.7.

I am sure Tom will confirm shortly.

Thanks

 

I'm not sure which products contain emulsifiers but I do know that most of the PS products do. Hopefully the diesel kleen does not have emulsifiers as I've heard it's a good product to use.

Either way, whichever additive anyone chooses to use, just make sure it does not contain emulsifiers and you should be good.


Thanks for the info as well Darren!

 

Sorry, bored, trollololol..

PM22A Summer, PM22B Winter since the truck was new.

 

NICE WORK, that's the one I was thinking of, thanks!

 

Brain lapse.....fixed

 

cool...thanks for the links.

I would like to use Stanadyne but I would have to order it online and have it shipped....DieselKleen is everywhere i have looked for it.....Walmarts, truckstops, parts stores, and some gas stations.

 

i just ordered some Stanadyne from amazon.com

Amazon.com: Performance Formula One Shot 8oz., Case of 24 Bottles Treats 30 gallons diesel fuel per Bottle: Automotive

 

Thanks for the links. Maybe it was the older formula of Diesel Kleen that contains emulsifiers, maybe I was just simply misinformed. I do know the 911 additives do contain emulsifiers though.

Either way, it seems to be cleared up.
