Hello everyone, apologies for the recent absence.

Anyways VTEC doesn't burn any more oil than a standard engine, although it is true that oil is an especially important component. Much like a turbocharger, without oil running there would be no VTEC operation. It uses a little extra oil, but it won't necessarily burn it.

Use of a fuel computer such as a VAFC to run the system ever so slightly lean at higher RPMs would unlock a bit more power, and would be ideal in climates where temperatures wouldn't get too cold (although you could always reset the VAFC to default in cooler weather). There's always a fear of burning something inside, which is why Honda set the fuel a little rich (that fear is accentuated in the higher revolutions).
