Oil for 2004 75hp 4 stroke

[ccarver80]

I need to add just a dash of oil to both the engine and lower unit.

For the engine can I just use normal 10w-30 automotive oil?? or is there a certain brand I need?

Same question for lower unit? can I just use some 80-90w? or should I stick with "Lower Unit Oil" specifically. I live in a small rural town and ill have to order special stuff like that online.

Use 80w 90 marine lube for the lower unit. If you have the owners manual should tell you what oil to put in the engine if not call the dealer or yamaha should have toll free #s.
