My Lude needs 91+ (why an '89 needs high octanc eI don't know).
My next hatch will get 87 until things require premium

whoever has the cheap regular gas and happens to be on my way gets my money
people, higher number doesnt equal "better" gas, all it means is that is has additives that make it less prone to preignition... so unless you are running high compression, you are wasting your money
high octane fuel wont even burn completly and cleanly in an engine that is not designed for it as the conditions in the cylinder might not be optimum for its proper burning point.

ok here's some info for the newbs/douches
when you compress air it get's hotter
high compression motors compress the air more (obvious)
gasoline engines run a mix of air and FUEL
so you bring the air charge in and the pisotn is coming up compressing the air
the air is getting hotter and hotter and hotter as it compresses more and more then boom is pre ignites from the heat of the compressed air instead of the arch of the spark plug
high octane fuel is more "stable" and wont' ignite as "easy'" so it won't preignite etc from the compressing of the air in the cylinder that is why you run high octane fuel.
you want to run the lowest octane you can get away with basically

i used to use sunoco 94 all the time for my b16. over time, it started to run like ****. i found out they add alcohol to increase the octane rating or something. i switched down to 91 like my manual recommends and i get much better performance surprisingly.
