Who here runs a fuel additive?

[Hydro-idi]

After reading Mels article http://www.oilburners.net/forums/showthread.php?33429-Fuel-Additives-Which-ones-are-best

Usually Optilube

This is what I was trying to find. Thanks!

Thanks! I read that but didn't know if things have changed since that was written.

I use xdp polar in winter and xdp diesel power plus the rest of the year. The bottles have the built in measure chamber and they are very economical. I have been in as low as -25 temps and have had no gelling issues, actually I did't plug it in one night on purpose and it got down to -17 and she fired up after 2 cycles of glow plugs.

Liqui Moly Diesel Purge

I read good reviews about the diesel purge but do not want to run it directly at this time. Everyone says you can add it to the tank and so does the back of the can. Liqui Moly customer service told me not to do that though, just hoping to get a few opinions before I do it now. Thanks.

It'd be fine to dump into the tank, it just won't work as well. You need like a gallon of it.

So maybe put in the bottle at like 1/8 tank and run it close to out would be better than adding it to a full tank?

 

[79jasper]

I would stay closer to 1/4 tank. If you have to just dump a few bottles in.
Obviously the preferred method would be like Al's Tech article, but some may not be comfortable doing that.

After reading that article I went ahead and ordered a gallon of the xpd optilube stuff. I had been running diesel clean in mind with just pure diesel but it's rather low on the list in comparison so I'll give that a try I guess.

Or;
Next time you change fuel filters, make sure one of your tanks is down to about an 1/8, then; take off the old filter & pour out the old diesel, fill this old filter with your diesel purge, using the same (low) tank the entire time run as close to empty as you dare, then fill this tank up. After you've run 5-10 gallons of diesel through the truck (still in the same tank) change to your new filter.

This will get you a run of diesel purge at nearly 100%, and catch most of the crud it knocks loose in your old filter, instead of clogging your new one.

Running optilube myself, or I would be running it if my truck was running.

That sounds like a good idea to me. I have a 1990 7.3 so I'm not sure if it's the same as your 6.9 but does the fuel filter just unscrew like an oil filter? Can't seem to find a straight answer. Can you give me some instructions on changing it if it is more than just unscrewing? This is my first diesel and I know not much as of now.

Unscrew and bobs yer uncle

Does 75% of double-filtered/dewatered French-fry grease & mixed with diesel count as a fuel additive???
(CHUCKLE)

That mixture is what I ran in my 1991 F-250 for over 50K miles, until a "terrible excuse for a mechanic" destroyed my AT & we parted it out & for about the same price as I paid for it.

yours, satx

Bobs your uncle, never heard that before I had to google it, thanks

I run DieselKleen in both my 6.9 and my 6.4
