with ur statement above, will use in confidence....already done if for almost 10 years.
since i was in form 4.
the best experience is in a kancil.
all standart kancil 850 + modded carb + naftalena = left dirt to kenari
i just put it in the tank before refill.
about 1pill/RM10..
don't matter what is the current fuel price.
so far no bad effect.
now still using it even i my civic hybrid.
