    As Amazoil was mentioned previously and is one of the Top, Synthetics on the market, I just did a quick search for Amzoil Dealers in your area and found 8 places that sell Amzoil within about a 10 mile radius. That would be by far the best way to go. But, ZDDP additives "should" be available at many auto-parts stores. If they don't have it on the shelf ask if they can order some in.

    If I understand, You have a used flat tappet engine that you want to keep from deteriorating with present oils. We can only guess as to the cam's condition as
    the previous owners may not have used the right oil . Break in oils and vr1 should be changed at 500 mile intervals. I used to use Rotella, but stopped when the zddp was reduced in it. It turns black and that upset a mechanic draining it from one of my motorcycles. It is ok for it to do that. Besides they put the wrong gasoline in it so I was not impressed. Rotella does not really have enough zddp.
    I use VR1 and change it often. I am now using 20-50 and yes, when cold it is harder to pump but in 3 minutes when the oil warms up, the oil is thin . Your winter temperature matters in oil selection so use 20-50 in the summer and change to 10-30 when it gets cold you will probably already have 500 miles on the oil in one season. anyway. "Hot rod oil" is another flat tappet oil you may find. The stronger your valve springs are, the greater your need for zddp is. You can pull them off and measure the force required to compress them to the length they are when seated and when open. I do that with a hydraulic press and a bathroom scale...warning don't go up over 300 lbs as at that pressure a bathroom scale bends and after it is kinked it does not work.
    Redline has a break in additive with zddp for about $12 per bottle...If you go the additive route, don't put too much zddp in as that is said to cause problems.
    (I do not remember the numbers for that but 1500 ppm is about right for driving ) you need to look it up.

    I contacted Rotella several years ago, they said their diesel oil has more zinc and works with flat tapped lifters.

    Correct, it is difficult to find information on the Zinc content in motor oils, STP is the most reasonably priced ZDDP additive, but I could not confirm that it contains a concentration of Zinc suitable to protect flat tappet cams.

    This will help: http://www.sccoa.com/forums/showthread.php?136304-What-oil-brands-offer-the-best-protection-

    I copied some of the above in case the link does not work

    film strength is said to be more important than zddp, but zddp matters.
    adding zddp additive can reduce the oil's film strength
    Exceed 1600 ppm zddp and wear increases

    commonly available oils listed in order of film strength:

    film strength psi ..........name........................ zddp ppm

    103,505 psi --- VR1 ( silver bottle) ---------- 1500 ppm
    101,139 psi --- VR1 (black bottle)------------ 1100 ppm
    95,360 psi ----- Amsol Z rod synthetic------ 1400 ppm
    90,266 psi ----- Quaker state defy------------ 1000 ppm
    86,260 psi ---- Joe Gibbs hot rod oil-------- 1100 ppm
    85,663 psi ---- Redline diesel----------------- 1500 ppm
    76,584 psi ---- lucas synthetic 5-30----------- 900 ppm
    75,409 psi ---- castrol edge------------------- 1200 ppm
    74,860 psi ---- royal purple------------------- 1300 ppm
    74,312 psi ---- Mobil 1 turbo diesel truck 1600 ppm
    73,520 psi ----- Delo 400 ------------------------- 1300 ppm
    72,022 psi ----- the new Rotella T --------------1600 ppm
    71,377 psi ----- brad penn grade 1 0-30 ------1500 ppm
    71,214 psi ----- the old Rotella 15-40 --------1100 ppm
    71,206 psi ----- brad penn 10-30 ---------------1600 ppm
    70,235 psi ---- Mobil 1 15-50 -------------------1100 ppm
    62,538 psi ---- Lucas hot rod oil --------------- 1900 ppm

    oils you should NOT use except for special purpose
    106,505 psi Lucas racing oil 3000 ppm too much zddp and short use oil
    103,846 psi Valvoline conventional racing 1500 ppm short use oil, off road only
    96,470 psi Redline racing synthetic oil 2100 ppm short use oil
    49,455 psi Lucas break in oil 4000 ppm for cam break in only (20-30 minutes)

    If your loose on the mains and rods, have large EDM's, spring squirters and other engine oiling "bleed" mods, and get the oil temps into the 280*+ range during race night, then use the VR1 20W50.

    From what I have read, use the VR1 10W30 and be done with it. The place that has the 20w50 can get the 10w30 for you, just order the right part number, that's all there is to it.
