Oregon Revised Statutes Procedure in Civil Proceedings § 12.155

(1) If the person who makes an advance payment referred to in ORS 31.560 or 31.565 gives to each person entitled to recover damages for the death, injury or destruction, not later than 30 days after the date the first of such advance payments was made, written notice of the date of expiration of the period of limitation for the commencement of an action for damages set by the applicable statute of limitations, then the making of any such advance payment does not suspend the running of such period of limitation. The notice required by this subsection shall be in such form as the Director of the Department of Consumer and Business Services prescribes.

(2) If the notice required by subsection (1) of this section is not given, the time between the date the first advance payment was made and the date a notice is actually given of the date of expiration of the period of limitation for the commencement of an action for damages set by the applicable statute of limitations is not part of the period limited for commencement of the action by the statute of limitations.
