RON95 or RON97??

[xxboxx]

read it somewhere before that RON95 not suitable for engine with 10:1 compression and above that doesn't have knocking sensor.

mivec compression already 11:1, putra and sgti (4G93 DOHC) is 12:1 compression. even though proton car have knocking sensor and the ecu will retard the timing but it means the engine would not run on it's optimum performance.

since 4G93 DOHC compression is 12:1, i'm assuming 4G93P DOHC also have the same compression, no? :stupido2:

4G93 DOHC NA is with 10.5: 1.
While 12:1 is from GDI version.
