It's hilarious the lengths people are going to reliably test ceratec. I saw almost no difference in Project Farm's video and his tests.

I think the typical shear test is a good set of information. I do not think it can define succinctly the goal of the product. These Audio responses I have recorded are good indicators of energy not going to noise and the wear that can occur. The significance of which may be small but every bit of wear saved is earned life. Shear is a very specific portion, if all motors were shearing constantly they would be very unreliable. They are made mostly to NOT shear

You have to drive the engine before it work on its full capacity.

​@@aciddiver1978yes it's supposed to take many hundreds of miles maybe a thousand or over to fully bed in. I used it in a 3 litre diesel with malfunctioning glow plugs. In cold weather the car took three attempts to start. After ceratec it started instantly. After 1000 miles I serviced the car and the oil was like water. The car had done 7k miles on the oil 🤔🤔is that worrying or not
