do you ITR owners have any problems about burning oil over long period of time when your in vtec or notice your lower sometimes after pushin it on the freeway for awhile if not what oil do you use? Because i hear it is common for all b series vtec motors when in vtec for along time you tend to burn a little oil from beening so high in the rmps?
first off i use penzoil 5w-30, and i trust nothing else, i'm not for synthetic oil, but that too works great, i like it simple, as for you question about the motor, i work on cars, and built a several motors, i've noticed that when you kick into v-tec, your oil pressure goes sky high, especially to engage vtec, and also the fact that your rev'n just that much higher and higher, over a period of time your going to burn some oil up, but it's not due to bad rings, or bent rods, just the fact the motor needs to do it that way, the best way to handle this is, when do an oil change make sure you fill to the second dot, most people say half, which is normal, but for these motors go to the second dot, and it will slowly burn down, and usually by your next oil change you will not have to add more oil, but always check it when you can, when your getting gas, or just sitting at home. Also if your vtec doesn't engage, or does engage and pop out of it, definitely check your oil, cause that means you don't have enough oil pressure, well that could be one of the things, alright there ya go, hopefully that helps.
