i have 25000m , is oil change enuf?

[N u B r e e d]

ever since i had my car ive been doing only oil changes and changed the filter once. anybody know what else i need to do to keep my engine healthy??reaching 25000 miles

[autxr]

Personally I'd change the oil filter every change.

I'd change the air filter ever year or 12,000 miles.

Other than that, no, there isn't that much to do.
