majority, if not all regular consumers need not concern about this

Over thinking

It's not even a contest! At less than half the price, just drink 95 la. Most cars even sports cars can drink 95 actually, just people saja shiok sendiri with 97! No such thing as 97 is cleaner than 95, or 95 only for NA cars. I run turbo car at 1.6 bar boost can still drink 95 with proper tuning making almost 400whp. If really die2 must drink 97, then mix 95+100 at ratio of 3:2, then you get same 97 at the price of only around rm3.2-3.3/ltr.

On most normal cars, honestly not really noticeable difference. People who says can feel the difference in performance la, pick up la, FC la, are all mostly just pleacebo effect in their minds only. If high performance cars then only might feel the difference. For example on my turbo car, yes can notice the difference when running 95, 97, and 100 but on my other normal NA cars with just half or less the power, I honestly cannot tell.

for BHP, Petronas, and Petron shown their additive package are identical for 95 vs 97. So safe to say put 95 alone also ok for engine cleaning. GDI dont say cz it will had carbon deposit doesn't matter with 97 all time
