i believe u were referring to vortex platinum? dats supposedly
rated at RON 100 but 4 some reason, caltex isn't declaring the
figures as such.
contrary to popular belief, higher RON petrols actually "burns"
slower than lower grade petrols. its hard to quantify on a
molecular level, but higher RON fuels basically leaves lesser
"competition" for air molecules to combust with which results in a
more controlled and consistent combustion wavefront.
this is general desirable for engines with high compression or
under boost because of their anti knock properties. with higher
ron, it means u can run more aggressive timing, higher boost
(therefore increase in power) with lesser risk of pre-detonation or
overheating coz the A/F mix also burns cooler at the same
time.
the downside is if u use it on e conventional non performance
engine, it can't really utilize the benefits of a high RON grade
petrol coz it was built with a higher threshold for poorer petrols
as well as to be more fuel efficient in that sense. therefore, u
might not feel any improvements if u are the owner of such
cars.
