Why does this car need premium octane?
You're supposed to use higher octane because it will prevent premature ignition caused by the engine's high compression. My motorcycle has a compression ratio of 12:1 and runs 87 octane. Does the TL have a compression ratio higher than 12:1 or is there something else?

These engine are designed for premium gas. if you compare millage per tank, premium gives you more millage for the money. There are other mechanical reasons,but I am no expert to advise or talk about those. Someone here can explain in much more details.

I've tried to determine a loss of mileage w/ 87 octane and could detect no difference in mileage or timing advance which would presumably be retarded by ECU to prevent detonation w/ lower octane. I've never detected a single ping.
It is possible that same engine may perform differently due to small differences in compression and valve timing.
good luck

Considering the era these engines were designed and their compression ratio, premium is perfectly reasonable. In addition, you'll get more miles per dollar of gas using premium in these cars. Don't go cheap, you'll reduce power, fuel economy and possibly have carbon buildup.

The reason why you'll get better gas mileage is because premium is recommended for the motor due the higher compression Acura engines have.
If you run regular, the engine changes the ignition timing to prevent premature detonation. This means your engine is running less efficiently. Less power equals poorer acceleration and poorer gas mileage.

CA premium sucks!!

if you wanna use regular use regular.. it will run a little worse possibly but will be cheaper this gas debate is pointless. i use premium because its only like 3 bucks more when i fill up

I agree with andrew. If you thng about it premium is only like $3-$4 more than regular (I'm talking about the price difference for full tank). With it only being a little more I doesn't take a major hi on the pocket at the end of he week. Some people find that regular MPG is around the same or close to the premium MPG. I have tried both and I find that prmim gives me the better MPG so experiment with it if you want to see what the difference is.
