    The US government may be against using food grade oils for vehicle use.

    I do not have a serious answer for your serious question but I hope someone does.

    In the mean time why you are at Wal-Mart pick up a $1.97 bottle of the WM Super Tech TC-W3 Outboard 2 Cycle engine oil and give your ears a break. Over on the diesel forums 1:128 is the typical ratio so that will treat 16 gallons or 32 if you go 1:256.

    Here is what turned me onto Super Tech TC-W3 outboard oil instead of Opt-Lube XPD. i use it in the gas vehicles for fuel pump lube from time to time but at like 1:500 (1oz per 4 gallons).

    Lubricity Additive Study Results - Diesel Place

    As you can see soy oil came in #1 over #2 Opti-Lube XPD. I think Spencer was the one that headed up the research. Super Tech was #7 but so much better than some of the ones so many use which some caused negative test results even.

    Gale, yes the soy oil came in first, but if you read the whole report it has its net negatives.
    As far as the Super Tech, not knowing what you are using it in, I would be leary using it. Read the whole statement from the report on Super Tech that I pasted in below.

    7)Super Tech Outboard 2-cycle TC-W3 engine oil
    Unconventional (Not ULSD compliant, may damage 2007 or newer systems)
    HFRR 474, 162 micron improvement
    200:1 ratio
    16.64 oz/tank
    $1.09/tank

    I spent $50 bucks on a gallon of Opti-Lube, and figure it will last me 2 years, that is like 50 cent a week, I figure spending that much on a 17k tractor is doable for my wallet if it is what I consider the best fuel treatment

    EDIT: I should have said read other parts of this thread and other threads when I refered to bio deisel, being a net negative, not the report itself

    The Super Tech TC-W3 seems to be one of the most common additives used by diesel owners and was included as noted because of that reason and the reseacher is not about to recommend it as an approved diesel lube.

    All of our gas and diesel engines are older than 2007 anyway, much older.

    Since by sound the Wal-Mart 7)Super Tech Outboard 2-cycle TC-W3 engine oil seems to be equal to 2)Opti-Lube XPD and I know is approved for gas engines too so it works out OK for our use. I agree on paper Opti-Lube XPD came out a little better than the Wal-Mart option and should work well for you.

    Wal-Mart does so much for our community I try to support her as much as possible.

    I'm running bio-diesel in my tractor, which as I recall has great lubricity. I dump a little power service in it for the heck of it, but I'm proabably wasting my money. In the winter I dump in some Howes for gelling issues. I wish I could get pure diesel for the winter, but they don't sell it in pumps around here. The farm diesel suppliers have pure diesel fuel, but they won't fill up my 5 gallon cans.

    I have been running Opti-Lube XPD for almost two years, in two different 4 cyl. engines. One is low time, one is high time.

    It has never made any difference what so ever, in either engine.

    is it even rated for gasoline engines?

    It is (I'm reasonably sure without looking at the label) designed and intended for diesel engines only.

    How can you know?
    Have you also been running identical engines with identical fuel doing similar tasks/hours without Opti-Lube and torn all 4 down for inspection and comparison?

    Just noticed these two old posts addressed to me. It is now 2 years later, I found this thread when I went to order more Optilube.

    I was trying to say before, Optilube has not made a noticeable difference. Today, I still can't tell if it makes any difference. But, since it's cheap insurance, I am still going to use it.

    Never said they were gasoline engines?

    Sorry I didn't explain that thoroughly enough. I was referring to the earlier claim in this thread, that an engine will ran quieter after using Optilube XPD. The fact that it was not realistically possible for me to know if there was any real difference in engine wear, as you illustrated, could actually have been a clue that I meant something else.

    I have a newer Duramax that I started using XPD in. Initially I noticed quieter operation which concurs with others in this thread. I have taken the truck drag racing a couple times just for laughs, and despite Optilube's claims of improved power, the truck actually slowed down in the quarter mile just a touch with XPD added. Also, and more alarmingly, the frequency of regen cycles doubled. Beyond the aggravation of driving around with a constant fast idle, I had concerns about my emissions systems so I stopped using XPD. After another fill up or two the regens returned to their normal frequency of once per tank thankfully. Overall my opinion of Optilube is the same as the snake oil comments earlier.
