Guys the currently available fuel is below 87. It's variating from 82 to 86 at best. I had earlier mentioned I will ask this from a credible source in the petroleum industry. And all this normal petrol being 91 minimum is only till theoretical boundaries. In practical existence it is still not going to be 91. What the sources actually said was upgradation while this RON number is not actually and in reality going to be available.
As per the info I have received upgradation will mean and tag the fuel as 87+ (plus) being added to it's name. By 87+ it will mean that the minimum required standard is 87 which currently is a maximum and I doubt anyone is giving this maximum 87 either. So the upgraded 87+ now means it could be 87.1, 88, 89, 89.3 and so on. This doesn't necessarily mean it will be 91. Please note that making hi-octane 91 into regular is not possible logically either. Have already shared this with @fazalwahab11375 and since source has to be kept anonymous. The info and attached proof can be used.
The term 87+ leaves a wide range of ambiguity which is going to be another pandora box by itself and involves only the formal tagging or appreciation for the establishment as "improvement of fuel"
Totally upto you guys if you want to believe or not. I have no personal loss or gain.
Now coming to Honda Civic Turbo. Every credible source involving actual authentic personnel from Atlas and not only my sources but as per other members here, they have clearly said "if you use anything other than hi-octane it's not necessary that car may develop issues, but if it does we will not entertain warranty. If anyone thinks how we will know what fuel was used, it's absolutely easy and simple for us to technically prove it"
The 87+ will however be of advantage to all cars using substandard fuel currently developing knocking issues even in 1.8 engines from specific pumps not just all 3 cylinder 1000cc engines from all pumps. Hence the minimum standard will be 87
