Whats up mga Bros?
I would just like to refer top you guys my predicament. Kasi I just recently bought a 2003 Honda City and its mileage is at 28500. I have checked with Honda Kalookan (where it was originally bought) on the service record of the unit. I found out that the last service was for its 10T Km, meaning hindi sya na-service nung nag 20T na yung mileage.
My questions are?
1. Ok lang ba na mag-proceed na ako sa 30T check up nya ? kasi the fee for 20T is at P6,600 while at 30T is at P1,700 lang. The differenc is that at 30T, the sparkplug is replaced.
2. Is it ok that I just change the sparkplugs from other service centers na mas mura?
3. What sparkplug brands would you recommend?

Thanks!
