Probably 5W-30.I use Honda brand because is cheap, but any good brand will
do it. Look in the fill oil cap.
You also need to check on the timing belt. If you don't know if the previous
owner replaced, you need to do it. Also, check the transmission fluid,
antifreeze (use Honda brand only) and brake fluid (any DOT 3 or 4 brand -
Valvoline DOT 4 is very good).
