i have a checklist from mitsubishi motors. i follow that. pero usually every 5K, change oil and oil filter, tune-up if necessary. check also air filter, clean if dirty. if very dirty, replace with a new one. every 15K, change spark plugs and follow 5K PMS.

guys, when you have your oil changed, do you use flushing oil? or no na, since you're going to use the same oil naman..? para saan ba ang power flushing oil (from caltex).

and do you change your gear oil (tranny oil)? coz ours 16yrs na ang car namin and i couldnt recall having our tranny oil being changed. any inputs? thanks!
