Apparently its a bearing effect, which reduces friction on the oil molecules and metal surfaces of the Piston and Cylinder.
Less friction this way leads to better throttle response, quieter engine operation and increased power and torque.
All of which I have noticed myself, they told me before hand about the coasting effect, nothing was said about BHP or torque gains until I asked because it felt like the car was faster.
If you have Millers, which uses a similar method, then you wont notice any difference with this additive, some other oils already do a similar job.
My Motul 300V clearly works with the Oil Smoother.
The old posts were removed because they were in the wrong section and potentially damaging sales for one of our traders.
If I can dig them back out I will post back in here
I should be able to, but still fairly new to this whole mod thing, lol.
I will see if I can find my spec sheet they gave me for it and post it here, it lists everything, albeit in bad English, ha ha.
I'm no expert on the subject, I am such a newbie when it comes to mechanics, but one thing I don't fall for is placebos, it was me that pointed out waxes/sealants DON'T make your car any shinier. I have spent all my life seeing though BS.
