    that used to be the case, but not because it would do something bad to your engine, but the fact they could not recycle the oil when mixed. Obviously that changed since we now have synthetic blend.

    What you may remember hearing is someone saying the vehicle leaked more after changing over to synthetic. Whether thats really true or not is probably open to debate.

    I think they now make engine oil "additive" that is for the seals (like they make for auto. trans) so as long as that was compatible with synthetic oil, that would be an option if you were worried about it.

    Out the bottom of the pan, or just out of the bottom end?

    Those seal conditioners (thats what I assume those tranny fix products are) would work on the main seals and perhaps the pan gasket (if rubber) but just in case you really meant the bottom of the pan, there is supposed to be a seal that is used with the drain plug.

    ive heard that the reason they leak more after the switch is that conventional oils leave deposits in the engine and the synth's clean these away, however these deposits are what is left of seals pretty much, and when they go away, leak time.

    I GUESS that could be true only because synthetic oil is sliperyer and could mabe get though the worn out seals and gaskets eaiser... ive also heard some time people have had slug /forums/images/graemlins/eek.gif free up when they switch to synthetic, but I dont have any experience with switching
    BTW that royal purple stuff is sposta be SWEET but REALLY expensive

    yea it leaks out the bottom of the pan, becuadse the pan itself is bad and rusted in some spots...were the PO had put some JB weld type stuff on the bottom..but it still seeps quite a bit.

    and whats so great about this royal purple stuff anyway? ive heard a lot about it..

    you cant just switch over to synthetic oils, they will free up sludge from the fossil oil and cause possible problems..ie plugged galleys etc..if you plan on swapping to synthetic, its best to do directly after the engine has been broken in on conventional oil...

    Eh...I don't believe that. Sure, it cleans your engine better than dino oil, but all oil has detergents. If any question, do a motor flush before installing synthetic.

    Hi Guys!

    What made you decide to go with Royal Purple, as opposed to a Mobil 1 or a dino?

    Synthetic offers superior protection to dino.

    Mobil 1, while good oil, cannot be compared to more expensive synthetics.
