    Type of Oil - Zinc additives - brands?
    by EJR8402
    I need to do an oil change on my '59 T-Bird with the 352 V8. I've done some research about the type of oil needed and it seems that these old flat tappet cammed engines should probably have oil with zinc additives.

    The prior owner of the car just recommended plain old motor oil, 10W-30. I'm sure that's fine if it's barely driven, but I do want to get it out a bit.

    So what...

    Why is it that so many in our hobby have gone to multi weight oils rather the “straight weight” oils we used in Ford vehicles in the’50’s & ‘60’s any even early ’70’s??

    I clearly remember using straight weight oils in Fords and multi weight in GM cars.

    My Vicky “sprouted” oil pan leaks after switching to synthetic oil. Torquing the oil pan bolts didn’t...

    What oil do you use for a hand held oil can to lube the various parts on the model A? Also do you use an antique oiler or a new one? The ladder is more curiosity than anything....

    Diesel Oil and The Model A Ford???
    by Leo
    There is a lot of "noise" going on at that other site regarding using diesel oil like Shell Rotella 15-40W in the Model A Ford engine. Many swear by it and others cite articles which have appeared in posts and on club sites which advise against it. However, I've yet to see a scintilla of evidence by any owners that claim an engine has actually been damaged through the use of diesel oil....

    Oil and the changes manufacturers are doing per the epa.
    by BNCHIEF
    This is not to say anything bad about any oil or brand just some info to consider. They are taking all the zddp out of the oil we run. Right now I have delo 400LE, being discontinued, I also have shell rotella T-4 both are 15/40 these still have the zddp in the higher concentration. You can also buy zddp

    Not the normal oil question
    by Standing Elk
    Let's see if I can remember enough of what I was told to ask this question. Apparently the EPA mandated the removal or maybe the addition of some component to motor oil?? I was told that the new formula now carries an additional code and that it should NOT be used in our motors. Can anyone shed some light on this? Thanks
