I have both a 86 200x and 350x but no owners manuals to go with them. There are 2 marks on the dipsticks, so the question is, where do u want the oil level?, and do u check it after it's been fully screwed in or wipe it clean and just dip it for a sec? My shop manual for the 200x just gives capacity,but it's not home for me to check right now, and i'm sure the 350 shop manual would do the same, heck, if anyone can even give me the 350's capacity, that would be great. Thanks guys!
