Hi Everyone,

sorry ha, newbie kasi ako... i have a couple of simple questions...
I brought my mazda familia to a nearby shell station for maintenance.
Oil change, flushing, filter oil, spark plug tune up were done and I was charged 1628 pesos. One of the ball joints were also changed and they charged 850 for the spare part and 250 for the labor (total of 1100 pesos).
They said problems with the fuel injection (EFI yung car) and cleaning of the throttle body can only be done sa casa. My questions are:

1. Is 1628 pesos a fair amount to charge for Oil change, flushing, filter oil, and spark plug tune up?

2. Is 1100 pesos a fair amount to charge for balljoint replacement (parts + labor)?

3. For people who've been to kia pasay, mas makakamura ba ako if the above maintenance work were done there?

4. casa lang ba talaga ang makakaayos sa fuel injection and makakalinis sa throttle body?

Your opinion will be highly appreciated. THanks in advance.
