1988 Evinrude 150XP. Just purchased. Previous owner gave me some lower unit oil. Partial quart of HPF XR and full quart of HPF PRO. Said lower unit currently had HPF XR and that on next refill to put in PRO and finish with XR as it will take a little more than a quart. Are they compatable? Cant find where it says this is correct oil for my lower unit.
