Re: Tohatsu TLDI 90 how much oil?
Altho they are different outboards, I own a Nissan 50 TLDI. It does make a huge difference on RPM. If I am running it hard (regularly wide open at its peak RPM of 5800), I can add a pint every couple of days. If I am running the RPM's lower...say 4500 then if goes several days. It does use oil but not nearly as much as a carbed unit. I only run Klotz Synthetic in it. It does not smoke at all.
