Spark plug question

[rocel]

Dati rin akong may 2E na makina gamitin mo iyong 95 0ctane pag 93 gamit ko may tope makina . at platinum tip matibay pero depende sa gasolina natin na may halong e10 na.
ordinary copper plug okay na basta okay ang timpla ng air fuel mixture ng carburator mo.Mas matipid sa gasolina at maganda sunog ng spark plug .

thank you sir!so preferable pa rin talaga to use premium than unleaded gasoline,the last clean of my carb is 3 years ago,last change oil ko kasi na dalawang beses ay di naman binuksan carb ko..kaya next project ko is change oil along with replacement of spark plugs and cleaning of carb..
thanks a lot sir!
