"TORQUE CUT CONTROL (AT HIGH ENGINE OIL TEMPERATURE) The ECM receives engine oil temperature signals from engine oil temperature sensor. To avoid VVEL performance degradation, the ECM performs the engine torque cut control at high engine oil temperatures. If engine oil temperature is too high, engine oil viscosity will change. As a result, engine oil pressure is decreased. This control affects the VVEL operating angle by operating the VVEL actuator sub assembly. If this control is operated, engine performance will decrease, then maximum engine speed is reduced a bit (Various levels of Limp Mode depending on temp).

I understand the VQ motors have lubrication needs that a standard pushrod or even standard o/h cam motor may not have, but until we can get a specific centistroke minimum threshold established (Nissan factory oil at operating temps??), who's to say that any high performance oil, in a reasonable weight range, wouldn't work under "normal" conditions? I just switched to M1 0w-40 yesterday from factory fill, mainly because I liked the results I got back from Blackstone when running it in my LS7. Apples to oranges, yes, but I have no hard data to say it shouldn't work fine in the VQ, especially with a 25 row cooler.
BTW, I realize Nissan recommends (at least that's what I've heard) ester oil, but the previous owner of my car showed me that every time he went in for an oil change in the first year, they used a non-ester oil. No warranty voided, so I'm wondering how critical the whole "ester" thing is anyway. I know, I know, here we go again with another oil thread. I apologize, but it seems we inevitably end up there. |
