I would stick with the Delo single grade 40 weight oil in an 8V92. I believe my 8V92 holds 7.5 gallons in the engine plus 4.5 gallons in the refill tank if it is empty (which mine never is but I always top it off when I change the oil). There is a sight tube on the oil refill tank that will give you an indication of how much it will need to top it off.
