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

If you look at your engines dip stick you will see minimum and maximum marks on it. The engine oil level must be maintained between these marks, any cause that means that this is not the case must be rectified. Carry a can of oil in the boot/trunk for topping up. The engine oil lubricates the moving parts, cools internal parts of the engine, and operates actuators on the engine such as Vtec valve. If the Vtec is not working, checking it must include an electrical check of the solonoid valve and it's operation, and the working parts of Vtec mechanism. This usually means a visit to the repair shop. High revs on their own will not starve the engine of oil, but an extremely low oil level, or a fault with the oil pump, or oil lubrication system will.
