Is Synthetic (full, not blend) oil bad for older (90-95) engines? Someone told me full synthetic oil isn't good for cars pre-94 or so, trying to figure out the purpose to this.
My wife's car is a 94 with 82k on it; I had thought it'd be fine but this guy started on about causing leaks and things, wanted to check in. Thanks for the input.
I think we discussed this here before, something about the sythetic cleaning away residual goop from the old stuff and revealing cracks/worn seals/etc that had otherwise remained plugged by the goop.
