On top of that, it uses a solenoid to unlock the cam followers on one bank from their rockers, so the cam follower floats freely while the valve springs keep the valves closed. Its kind of the opositve of vtek. Below a certain rpm level it shuts 3 off by closing all valves and not allowing any air in or out. Not sure how the damn thing doesn't explode!... my point was that now that we have essentially a 3 cylinder engine, the old theory of higher octane is better may not be valid anymore for many reasons. Your back 3 cylinders on the v6 that get cut off when the CVM kicks in may end up a lot more "new" than the front 3 that work all the time. So, you have 3 old and 3 new cylinders both receiving the same octane gas. Weird. The Odyssey people say they never experience any issues, too early to tell?
