Well stated Gary.
There was no intent to convert this thread into an ARX thread,
nor to turn into a
frequent oil change thread.
I simply suggested TWO
alternative options that might save you some headaches in the future, such as ARX OR frequent oil changes.
Please notice that I asked a question as to why you thought you would need this OTC additive. I.E., what tests had you run that led you to the conclusion that you needed this product?
Let's say hypothetically I was a mechanic and you brought in a high mileage vehicle to me with a performance complaint. Let's say I tested the compression and found one or more cylinders with low compression.
Sure, I might recommend the Rislone goop for a short term fix, but as a conciencious mechanic, I might also recommend some alternatives for a longer term fix, such as an engine cleaner or ask you to come in for more frequent oil changes and see if that helped your situation. Of course, eventually I might suggest a rebuild with new rings, valve stem seals, etc.
However, if your cylinder compression was within specs for that engine mileage, I might recommend a set of plugs, wires, injector cleaning, intake and fuel system cleaning, CAT replacement, etc.
So what's the point? I am trying to get the customer to think about WHY he really needs something (based on science or experiment), rather than falling for vapor advertising or internet sludge.
