isnt it the other way around? initial "dosage" is 5% ratio and then 2% ratio for maintenance?
either way, pwede. pero you're correct, 2% ang maintenance dosage. If you want immediate effect, start w/ 5% or even 10%. But make sure you replace your fuel filter within a week or so after you used 5%-10%. This is to make sure that whatever scum that is cleaned out of your fuel and lines is removed thru the fuel filter.
Kung ayaw mo magpalit ng fuel filter agad, start the other way around, 1%, 2%, then 5%. But eventually you have to change fuel filter. then back to 2% maintenance dosage.
