OK, but do you think "High Mileage" makes up the bulk of the Mobil 1 responses? I'm guessing not, but dunno. If most are using the regular Mobil 1, then the message the poll conveys bothers me - it is missleading w/ regard to what should be used i.e., a higher ZDDP oil
Put another way...
If the high percentage of use is based solely on that sticker under the hood of all 92+ MY Vettes, then there is potential for problems and it knaws at me (though oil - related problems don't seem to appear all that much - on this board at least).
Maybe ZDDP in the LT5 is not that big a deal (to some). But, I can't see me rolling the dice on mine - Make mine synthetic w/ ZDDP comiserate with 1990.
I'm just sayin...the graph bugs me cuz it (to me) clearly recommends the wrong stuff.
