AI460 oil quantity

Question

I have a 2005 Granite with AI 460 engine. How much oil does it need at regular oil change? Also has 18 speed trans, 433 gears and 22.5 tires. I run 65mph a lot, engines turning  a little over 1800 rpm. Loaded, the truck weighs around 73500 lbs. Would putting 24.5 wheels with 11r 24.5 tires help or hurt? Seems to me its geared a bit low.

Thanks

AI engines have a narrow torque curve on most models.  If your gonna run full size 24.5's you need 4.42  to 4.64 gears. I would stick with what you got.  On the older ETECH's you could get by with even 4.17 gears but with the AI's no way.
