Hi RxxR.
Trying to keep up with others, "driving like a madman" is something that i very rarely do (only in a no-option scenario).
Usual drive style is very short trips (less than 10minutes at 30miles maxspeed, 99% urban drive), with fuel economy in mind.
If you research BITOG on Hethaerto's Xado test with his Trooper, although he felt a positive difference in the first 400 miles, he reported it was worthless after, but claimed to get the results he expected with CerMet.
In my opinion, a certificate may give one peace of mind, but does not assure a product will work for you, only that promoted some degree of benefits in a given test scenario.
The only (expensive) way to find out is to try it yourself.
I'll wait for the full details on that TUV test, just out of curiosity.
CerMet isn't directly available in my country only XADO, otherwise i probably would try it in my engine.
But if you try it, i do hope it works for you.
All the best.
