Not a fan of the zMax price tag, and after the whole commosion/lawsuit with zMax a while back, I don't know if I'd trust it.....if I recall, the judge basically stated in their findings it showed no improvements that the product stated.....
Seafoam and/or Marvel Mystery Oil - on the other hand, are tried and tested and you'll find fan clubs all over the Internet and local mom and pop garages that support those 2
Though I've never had either additive "save" any vehicle, I have experienced their cleaning power within a short OCI...and am a believer.
In the end, it all depends on what you are wanting out of the product.....if you want to just clean up any possibility of sludge/varnish within the engine, sure, go ahead and give the seafoam or MMO a try. As far as zMax.....I'm not sure exactly what it's "advantages" are....If I recall, there was some talk about it "soaking into metal" or something lol.....that almost sounds like that "Restore" stuff, which seeks out weak/hot spots within the engine/head/cylinders.....but who knows
