After doing some research, I understand that the sluggish feel (weak throttle response) of altezza is caused by the heavy dual mass flywheel which weighs about 12kg.
:hmmmm: Just wondering if it is okay for me to use Ron95 for my engine. Because I read some post that say high compression engine need to use Ron97 (eg:Civic Type-R) Any ideas all sifus? Mine engine is stock standard...
