Hey Elvis, why you worry about these things now that you got the real thing, one more remap you'll be sorted for about 12 clicks a litre but that CA. of yours!!!
A good oil has better detergent properties which cleans up ur engine and results in turning the oil black but also a car running a richer fuel mixture than required could blacken the oil sooner caused by bore wash.
I'm prepared to put this nano thing to the test and see if it actually works. I need somebody who's about to install one to come in for a wide band air fuel ratio log before and after installation. Any difference in combustion (if any) will be displayed/stored in the log for comparison. This test will tell if its really working as advertised and I'm prepared to test couple of cars at no cost.
Cheers
Zakie
