I've always used Techron in my Boxster. Have I had any issues? No. Have I seen any benefit? That's a difficult question to answer, as I have no baseline to compare to. Why do I keep using a product that I cannot verify any gains? Because I'm a creature of habit. Do I enjoy wasting money? I suppose so, if it provides some deterrent to the "wish I would have kept using Techron" scenario that I might encounter in the future...but then again, I don't see it as a "waste", more of a proactive payment. Do I use Techron in my other vehicles? No. Why not? Because I'm not hopelessly stupid, just partially so.
