HI guys ... need some advice. Got a quotation from a Honda casa for the scheduled 40k kms. maintenance for my 03 CRV. The labor cost quoted was Php 3.2K and the parts Php 8.3k which totalled to Php 11.5k. Upon review of the scope of work, it included the normal 40k kms check up plus change of air filter element, change of automatic trans fluid, change oil & filter. Mas mura ba kung ako na lang bibili ng parts and have it done by a mechanic or have the motor/ auto transmission oil changed at a gasoline station ? Meron ba kayo ma recommend na pwede gumawa nito so I can save ? Medyo mabigat na kasi to pay Php 11.5k. Thanks ...
