    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.http://www.restore-an-old-car.com/be...ssic-cars.html 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 https://www.thoughtco.com/...

    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

    Switching to synthetic oil
    by Michael M
    So as not to hijack the other oil thread on here, I thought I would ask a new question in a new thread.

    It seems conventional wisdom says you can mix conventional oil and synthetic. Its also been reported that conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.

    It's also a given that a quart or more oil stays in the tray...
