I usually pour a bottle of it everytime after 10k service interval. All fuel already hv detergent in it. It's just that this product is more concentrated & i added it every 10k to serve as a preventive maintenance to clean existing carbon deposits & minimize any future build-up.
U might also wanna consider revving ur engine hard once in a while. It is a method which they coined it as "Italian tuneup" & it's what the technicians in Ferrari do after each service maintenance to rid carbons. The key is to rev ur engine hard & get it hot enough to naturally burn off those carbons.
Actually, that seemed somewhat right. I remember I drove outstation alot, and I drove hard. I remember there was minimal to almost no pinging during that period. But the car now is just 100% city driving, alot of traffic light. So I guess there is no chance to rev hard and burn off those carbons unless I do it idle. But there is a rev limiter that cuts off at 3k RPM.U might also wanna consider revving ur engine hard once in a while.
