I've had CerMet in my 2002 Volvo XC70 for about 500 miles now. I'm now a believer in CerMet.I plan on keeping this car forever. It's a great vehicle, and I sincerely want to drive it until it explodes. So I've been searching for techniques and products to help push out this car's lifespan as far as possible. I've been using a certain PTFE engine treatment for the last year, and although it provides substantial performance increases, they don't last. I suspect the product settles and possibly even causes oil flow blockage. I changed the engine oil without a flush. I was running Amsoil 0W30 Signature Series synthetic oil. It was a fine oil, but seemed to introduce drag into the engine which required me to step deeper into the throttle to accelerate which reduced efficiency. I switched to Castrol GTX 10W30 and added two 10ml syringes of CerMet. The car instantly behaved very differently because of the oil change, but that performance increase slowly subsided as the oil broke in. The break-in of the petroleum oil finally leveled off and I've been experiencing startling performance increases from your CerMet product. The engine is quieter and smoother. I read that CerMet somehow helps to balance the spinning engine components. I would say this is true because my engine produces far less vibration and noise now. Fuel economy has increased from 21 to 23 mpg in the city. I've not taken a road trip yet.I really enjoy the instant throttle response. No more lumbering slowly trying to get the engine to rev. Revving is instantaneous, and the car takes off like a rocket. This performance increase is very similar to what I experienced with a certain PTFE product, but CerMet's effect is constant, and only gets better day by day, while the PTFE's effect was good for a few days, then faded. I have no scientific data from a dyno or a used oil analysis to back up what I call "performance increases". All I have to work with is fuel economy and how the car drives. With CerMet the car drives like a dream without performance fade. I'll be installing this product in my other vehicle very soon. CerMet: The Holy Grail of engine treatments. Maleficio
