well there is no zddp in most all oils made now .it will plug the cataytic converters. that is why most race oils have the zddp and will say not for pollution controlled vehicles you can added all the whizz bang stuff you want .but it can also sit in the bottom of the oil pan. may or not mix then you get in to a oil clash. may work and may not at the time needed . i use a oil made for the job brad penn or joe gibbs .hi detergente oils can block the zddp from bonding .a fast burn zddp is what you want for break in that will go in to the micro valleys of metal parts bond and turn it to glass like micro finsh this is what the fast burn zddp will do .it will not work if a hi detergent oil is used as this will block zddp from hooking in to the metal part and stripping the zinc if it makes it there .diesel oil may not save your butt as the load from the hi cr has a slower burn rate then most street engines and were you may need it the zzdp may not be working for you .so there is more to this then just saying a oil has zinc but to say a oil has zinc that will work for the job at hand . this is what lake speed from joe gibbs was telling us so i will take has word for it . why be cheap? or spend money on oil and a mix that makes you feel like your doing some thing good for your engine when it just may not do any thing ?oil is not home made soup you can mix at home ? when i build a engine i want the oil that works
