Vtec car owners, is it true that You have to use premium gasoline instead of normal gasoline due to the high compression of the engine?

No, Premium would help significantly (as it does in most cars) but it is not a requirement. Just like any factory boosted vehicle, premium is highly recommended but it can run off a lower octane no problem.

Follow the owner’s manual for the car. My car, which has the 3.2L Type S V6 VTEC engine, does highly recommend premium fuel because of the fairly high compression heads fitted on it.

Mazda Skyactiv engines run at 12:1 Compression and work fine off 87. Something similar for V-Tec I’d imagine.

To all of you that responded to me on this post. Need to learn about what the hell you’re talking about, cause apparently none of you have any idea.

its more than just compression, your ignition timing is also important when determining what grade of fuel you’d like to run…

theres is more potential to be had with premium fuels, but you will not see any differences unless you tune accordingly

-its is true however some cars will have a high enough static compression they will require hi grade fuel to prevent knocking…. is this the case with your honda? probably not, yo
