Many claim that during an Arx treatment their engine will make noises, knocking or tapping, and this is cited as 'normal' as oil gets to places that have previously been starved.
To me it suggests, it's more likely, that during the cleaning larger particles are breaking away and temporarily blocking oil flow. Unless someone can explain why an engine makes a noise 'when' it gets oil and 'not' when it doesn't?
I have used Arx, I did not note any changes in the engine, it was expensive and I tend to believe that there are other products that will do a more effective job.
But thats just me. I'm not about to argue the point.
