    Does anyone run Opti Lube XPD in their trucks everything I have read seems to say it is pretty good stuff. I need something that I can run in my IDI as well as my Powerstroke. Right now I am using Howes but it looks like Opti Lube is a lot better.

    I am running Howes right now and my startups have improved. Never used the Opti Lube but it might be worth it.

    I seem to recall some tests posted somewhere on the net that were done by a branch of the military on that optilube stuff that didn't put it in a very favourable light. That said, I'm rather partial to Howes since it kept me alive running big trucks in the great white north in insanely cold temps where I had gelled up on every other additive out there at the time at least once, but never with Howes ( remember for pickups and cars you have to use double the dosage listed on the botttle, this is due to the slow flow rate on them. Big rigs have a very high return fuel rate that is usually enough to heat the tanks on it's own if they are blanketed ( those purdy diamond tuck quilt covers you see on northern trucks tanks are not just for decoration )

    It seems to be of higher in lubricity according to some tests, probably the same test that you saw. I would try it if I didn't have to order in online.

    I have been running OptiLube since 2007 and it has been great in all of my diesel cars and trucks.

    The TDI club has a group buy on it now. $4.75 shipping on gallons. Thats a 15 dollar savings.

    enjoy

    I don't see something as simple as an additive affecting mileage much at all. I could see if helping a bit, but not being any worse than without it. Unless you're buying it by the drum and running it straight.
    The only things I could see lowing mileage as far as additives go are: unleaded in the mix, alternate fuels, and large quantities of water.
    I don't run additives EVERY tank. Just now and then. I also don't measure it, just dump some in. Reason being, I don't see how 8oz can affect 30 gallons enough to make a difference.
    I get the whole needing lubricity, but is there any hard evidence showing damage from low lubricity(when proper filtration is used)?

    I have run Opti-Lube for a couple of years now and will continue to do so. I will sometimes throw in some DieselKleen instead once in while. I decided to use Opti-Lube due to the wear test results. I think our DB2 pumps need the extra lubricity put back in the ULSD from an additive, but some say the ULSD is not really a problem for the DB2. I have also used Stanadyne Performance Formula with good results.

    i wonder just how much lubricity any modern additive adds. they all meet ulsd regulations, so how much more could they really add?
    i don't doubt the cleaning power or ability to fight waxing.
    could the lubricity be a simple as adding sulfur to your fuel? probably not that simple but would be nice.
    i've got some howe's to try when i'm out of the white bottle dieselkleen, from what i've read it's about the best for gelling so i'll
    probably stick with it.

    You can't just "add" sulfur to fuel. Sulfur is a solid at any fuel temperature an engine will ever see. It doesn't melt until 240 degrees or so. The sulfur that is removed from fuel is done at a refinery on a molecular level and not something you are going to duplicate in order to put back in. Actually if you ground up sulfur and put it in your tank, all it would do is plug up your fuel filter.

    that was more of a rhetorical question than anything.
    but thanks for the educational answer.

    No joke.... after that first post was searched...... 20 farm boys around here were off to the feed store and were spiking their tanks already :D They're probably still sitting around scratching their backsides wondering what happened :rotflmao
