Jacking car to a level position
Destiny, the diff and gears do not have to deal with by products of combustion, and turn at a much slower speed than the engine, also they are not heated to the same levels. The additives are for extreme pressure, and the "shavings" fall out due to gravity. The factory intervals account for shear and the additives do not typically wear out. Synthetics have seen 500,000 to one million miles in 18 wheelers that gross 80,000 lbs. These applications see torque numbers per sq. in. that exceed ours. Frequent changes are overkill, but hey, it's your S2000!
Cdelena, how do you change your tranny oil without lifting all 4 wheels, and teadiously leveling the chassis? I have always spent a lot of effort with a level trying to get it right before filling it.
My garage slopes toward the garage door for drainage, so I have to raise the rear a bit more than the front for it to be level. There is also enough of a variation in the floor that the car won't sit flat on 4 jack stands. It will rest heavily on 2 opposing corners, and teeter between the other 2. I hate letting it sit like this, since it puts a tremendous amount of stress on the chassis (twist). I now just put 2 jack stands under the front, lift the back (at the differential) with a hydraulic jack, and place 2 jack stands at the back corners (just in case the jack gives).

Jack up the car beyond level and keep track of how much oil you use... isn't that hard to do because Honda's MTF is marked on the side for deciliters and ounces. I stopped at 1.8 qt for a 10% overfill.
