Of course changing the oil without a filter means that new oil is
contaminated with some oil and that surge of new oil may have washed some of
the dirt on the filter element through it. Otherwise go for it. You won't
lose much. Be sure not to overfill when topping it off. Between the marks is
good. The top marl is not the full mark. It is the "do not exceed no matter
what mark".

Subject: Oil filter change w/o oil change

Can I drop and change just the filter on my 91 wbx  (just did oil but didn't
like the available filter)  and if so, how much oil will I lose and need to
replace.
Thanks,                                Mark Drexler
