Hi to all fellow tsikotters!

I would like to ask some newbie questions and I would appreciate if someone can help me out.

I am planning to have a change oil plus change in timing belt.

BTW : My ride is a lancer bilog

Change oil with tune up
plus timing belt

Questions please

1. What kind of oil is ok for my ride?
2. What spark plugs and filter to use (brand name)?
3. For the change in timing belt, I know I read somewhere but can't seem to remember it. That I ought to do some other things / maintenance aside from the change in timing belt.

I am planning to do the regular maintenance and any more inputs is very much appreciated.

Thanks in advance!
