Thanks Beeza,
I think cerma will work differently with different cars.
I put cerma on my lancer (car is gone now-transmission) at about 360,000 km on the clock. I put the cerma shortly after an oil change (John's recommendation) and drove it as per instruction ( took a detour from normal route to work) on the day it was put in. My drive to work is 35 km each way and mostly 80-110 km/hr. I didn't notice significant change until one day I took my car to Bathurst (for work) in an area where there are a lot of hill climb. This is about 8000 km after I put the cerma and noticed significant difference. I changed the oil probably 4000 km after that and I wasnt 100% sure, if the improvement carries over to the next oil change as I always use good synthetic oil (redline and motul).
I think cerma works if the car temperature get elevated to a certain high level and I'm not sure if it will work with Honda as it is a relatively smooth engine. My brother has an old laser and it runs hot. It probably work well with that car. So I think cerma is not for every car or everyone. It won't work if we drive it gently.

Let's move on. John Murray would need to send a free sample to Fred and I so that we could do more testing with it. Can you please ask John to do this?
