Nothing. I tried two different things in my 01 before and didn't change anything. Haven't used anything in my 04, and won't. Instead with my slip tank I added another fuel filter, IMO if your worried about your fuel make sure it is getting good filtration more then anything.

 

WMO = Waste Motor Oil???????

You are kidding?????

 

Below is a web address for the results of the fuel lubricant study:

PS: I use the Opti-Lube summer blend and have no complaints. I switched after reading the study and finding that one additive I used made almost no improvement, and another actually reduced lubricity of the fuel.

 

Only thing I've noticed that helps it run smoother , is hook up 10K and yank it hard for about a 1/2 hour.

 

What - you never heard of that?

 

i guess not,,,,I'm sort of a newb when it comes to diesels,,,,

how do you filter it????

 

Here's the current setup:

The Wix is 12um and the Motorguard does submicronic. The pump is, well, a pump.

 

Now you've got my attention,,,, how much does all that cost????

and how much do you add to a tankful??????? I am already running Wally world ashless TCW-3 @ 128:1 and you mix the WMO @ what ratio????

 

It's about two hundred bucks (at eBay prices) worth of junk hanging on my garage wall and a half hour of my time several times a year to drain, re-fill and shuffle jugs around. No trips to the recycle place with dirty oil anymore. I've been running the add mix about 65/35 WMO to 2-stroke. I cut it with Howes during the cold months to something like 50/30/20 WMO/2-stroke/Howes.

 

Cool!!!!!

What ratio to ULSD in the truck ???? (How much per tank????)

 

IF IT IS CLOSE TO YOU - - - WHY NOT USE THE BEST-- BIODIESEL? ALSO AT NO EXTRA COST- AT LEAST WHERE I LIVE, IT IS SAME AS USLD. IF IT IS CLOSE TO YOU USE THE BEST- OR WASTE MONEY.

 

Might add this WMO fuel additive will only really work in a 1st gen. THose old 12V trucks could run anything!LOL I would not use that mixture in a 3rd gen ever.

 

I was just about to ask ACE if this was for his 1st gen or if he ran in it in his 07 as well.

..

 

I don't run any additives in my truck. No ATF, waste motor oil, additive, 2 stroke, nothing. Playing with fire putting that junk in a CR system. If you want it to run quite, pull a heavy load or run some B5 in it. B5 is getting really common in my area. Shell is selling alot of it.

 

I run the same fuel add in both a 1st Gen and a Common Rail. I believe the CR actually needs it more due to the extremely high injection pressures and more sensitive injectors.

It's not a question of what they "can" run, it's what they "need" to run (better). The first time I put 2-stroke in the CR, the engine showed a clearly audible and tactile improvement - smoother and quieter. YMMV. If it delays me having to buy injectors for even one year, I'd say well worth it. I'm countnig on it from preventing me having to buy new injectors ever.
