Huhuhu 53c difference with 95! No problems, got plenty of octane boosters already.

Rich people la, and usually such cars are rarely driven.
What car do you drive actually, I can't recall. Most normal cars don't need 97 actually, just people shiok sendiri! Lol
I use Bardahl on my Evo and Swift Sport.

E46 just drinks pure 95 no issue, just like my Mark X. Barely any difference, I don't even put octane booster on my Mark X. If I were you I won't even bother with octane boosters for that car.

I got from shopee, just around rm10/btl. Tested on my Evo, it works good as my check engine light not flickering/remains off even during boost up to 1.4 bars. If I use pure 95, it may occasionally flicker on boost meaning the ECU may begin to retard timing just a bit.

Yes I'd think not really significant effect. My Mark X fuel range recommendation is 95-98 but also don't feel much different when drinking 97 no matter how hard I drive it. Same case with Swift Sport to be honest. I suggest you just try first with pure 95. It surely won't damage your engine, just a matter of whether you can feel the slight performance gain or not. Me personslly, I'd only consider filling up 97 on these cars if the price difference is less than 30c.

Woohooo, another 10c up ya. I love octane boosters! Lol

No, all octane boosters now use MMT, no more lead cuz lead is already illegal.

No, it won't.

Edit: sorry, it seems got inconclusive studies wherrby some study may show impact while others not. What most mention consistently though that it may accelerate spark plug wear.
