Does it matter if I use regular instead of premium fuel for my Acura Legend 1991?

check your manual it may say 87 octane only or it might say premium only or maybe even premium recomended which means you can use regular.

Most cars actually run better on regualr unleaded than premium, b/c the premium gas is to rich.Check your cars manual.

it runs best on what maufactor sez but reg will NOT hurt it...computer makes the timing changes for lower power.

89 octane/ 87 is a little dirty, but theres really no diff between 89 and high test.

Have you ever seen a tanker truck with separate tanks? The gas is all pumped through the same damn pipeline. How can one be better than the other?Don't fall for this goddammed ploy! Gas is way too much as is. We should revolt and start stealing fuel. How can you make us pay for sh!t that they pump from our earth?

Only if your engines "knocks" or "pings" with the regular fuel. Some engine systems are designed to automatically adjust to reduce or eliminate knocking; others are not.The knocking or pinging sound comes from gas exploding too early, which not only reduces performance but also will destroy your engine over time.

Legends run just fine on regular.

Have you checked your manual? I'm pretty sure that the only Acura vehicle that can run fine on regular is the Integra, which later became the RSX.

If your car Knocks on Regular, than Premium will cure that problem, if U don't care about performance, than regular will work.
