Just got my first vtec honda and vtec isn't kicking In and before I take it to my mechanic to see what it is I'm curious to know how low the oil has to be to effect the vtec. My oil level is just in the optimum range but I read that high revs starve your engine of oil so I was wondering if just that tiny amount of lower oil level may be causing my vtec to not work? I know I can just go get some oil to see if it fixes it but I'd like to know for future references just how low the oil has to get to effect vtec
