i didn't say in asia 92 =87, don't get me wrong! i only said the standard in asia is diff than here (possibly) and cars running with 87 in general will have more issue with check engine lights and their o2 sensor / knock sensor etc seems to go easier than cars running in higher octane...
of course, you can do whatever you wanna do; you don't have to use 87+ if you don't want to?
and when are we talking about brakes now? what about reliability and handling? come on, stay on topic ;)

yeah in most case if you are not pushing it uphill / running it so hot on the freeway all the time, 89 should be enough but say in general most ppl gets 12k to 18k a year, 1 tank of gas in 87 to 92 is about $6/tank, say usually ppl gets 400 to 450 a tank, it's only $270 a year (not even $25 a month, assume it's 400 a tank, 18000km a year) and long term wise, i still think it's a better investment?
of course, if you don't mind random check engine light (such like one of my friend, his car kept having check engine light and mechanic always told him nothing is wrong (sensor was replaced) and as soon as he switched to higher octane, check engine light never came back again...or random stalling on a couple 10 to 15 years old car with less than 200k (all tune up etc are done, nothing could really be needed)...
also, buying a new catalytic convertor, especially on new cars, ain't cheap! it's like my friend didn't change his coolant cause he thought he has to do his timing belt soon, last week when it was minus bomb, radiator blew up...not worth it (well toyota told him those are long life coolant)  |
