Thank s ... Iapologize for spelling arrors due to translation |

is your fuel 95 RON.?? yes it does rearly need 98RON fuel for best performance and smoothness. do you know what ecu calibration id your car is like ZA1JA01G. IF your car was made before mid 2013 it may have an old ecu calibration and dealer should reflash if you have idle problems. suggest you take to dealer and get them to check |
we only have 95 RON here in SA and our cars seem to run ok with them, even though the fuel flap says 98 RON only

if you have ecu logging device have a look at your IAM its probably about 0.5 or less and you will have sognificant knock although you may not hear it. you guys run same ecu calibration as here in australia and i have seen stock cars with IAM of 0.7 or less on 98 Ron fuel and knock correction of 3 or 4 degrees. however the original poster apears to have other problems possibly related to early ecu calibrations such as 700 900 or A01 ecu calibrations or the cam actuator problem if his car is running that rough and stalling and idle dip and stability issues. |

sounds car has a problem though if its under warantee should take it to dealer |
Unfortunately, my friend KSA is not as many people imagine
Is the use of 95 will damage the engine....؟ Or just about losing power....... I need to solve problems ....Or may be forced to sell:cry: And I will make sure of the date of manufacture of the car soon |
The use of 98 is recommended the use of 95 is required so don't think you have a fuel issue. Since mine is a daily driver and I am not worried about top performance I run 91 (the NA equivalent to your 95) pretty much exclusively with zero issues.
Like has been said already get you ECU flash level checked as that is more likely your problem. |
You could always add some octane booster at every fillup.

so what you are saying is that with the knock you mentioned above, this will actually affect longivity of the engine? |
Quote:
the ecu should control knock well enough to prevent engine damage. however if your car is stalling and idling erraticly this is likely to be another problem and you should get that fixed |
Good morning
my car date of manufacture JF1ZN12........ Tomorrow I will meet some friends All of them have 86 We will Cheak the lgnition coil |

if your car is pre mid 2013 manufacture there is likerly an updated ecu calibration the dealer or you can flash. |
95 octane is fine. The engine will adjust the timing.
Also, the idle RPM without A/C is only 650 rpm so 800 should be ok, unless if it is fluctuating all the time. If the RPM is fluctuating without A/C and check engine light on then bring it to dealer! |
