5th gear VTEC

[Turbodude06]

Ok my car hits VTEC at 4500 RPM and thats about 90 on the highway in 5th gear is it bad to stay in VTEC or not just wondering I just took a trip in my car and I tried to stay under 90 because I didn't want to hurt the motor, or I heard it burns oil if you stay in it too long. Is this true??

Nope. You can be in vtec all day. Burn WAY more gas tho.

^^ yup yup

I wouldn't say its good to be in VTEC all day. I try to stay out of VTEC if I can, espcially on the hwy so it doesn't burn as much gas.

its ok man, I'm assuming by your screen name and 4500rpm you have a b18c1 so thats ok dude, you're not in full throttle yet either until 5700 or so when the secondaries are wide open. I use to be in vtec all the damn time on the highway coming home from work (smyrna to gwinnett) which its ok, just a little more gas consumption and maybe a tiny bit of oil, but other than that you're good. Now if it bothers you that much just replace the intake manifold with a single stage manifold i.e. skunk2, blox, aebs, etc. But if you do replace it then don't forget to replace/chip the ecu so it'll run right, The p72 will run like straight shit on a single stage manifold so some tuning is suggested but not required, mainly because the fuel curve/timing is changed when vtec is altered i.e. vtec was set at 5500 but you changed it to 6k then the fuel/throttle or what not needs to be changed to match the vtec engagement. Sorry if this doesn't make any sense, I'm just used to working on a v-afc so much.

Is this true??VTEC is just a change over in the cam lobes, no big deal....but it will burn more fuel.

BASICALLY------ NON-VTEC = less burning of gas
VTEC = Burn more gas

ok well thanks I was just wondering so next time im on the highway I wont worry about staying in vtec for more then a couple of seconds, I'm not worried about gas consumption, more the oil part, but if its not a big deal then I guess I have nothing to worry about.
