I have a 2005 Nissan Murano and it says that it recommends premium fuel on the gas cap but I am not sure what it requires any input?

Regular is ok unless someone is using a high performance vehicle that requires #1.

Generally, use what the manufacturer recommends. With the computers in the cars adjusting for air and fuel mix, you probably can get away with using regular, but don't expect premium proformance while using regular fuel.

it's best to follow what's specified, however,

you can use mid-grade if you're not driving in a 'spirited' fashion

you should be able to use regular 87 if you drive like gramps

you could get away with 87 no ethanol if you can find it. I have a 2013 Acura ILX and it says premium recommended for 'optimal performance' and regular 87 runs just fine, no issues what so ever.

Use premium to prevent detonation and possible engine damage. Modern cars are equipped with a "knock" sensor to detect early detonation (pre-ignition) and retard timing to counter. But, if the sensor fails, engine damage can occur.

Stick with premium. Spend a few cents more now to possibly save thousands in repairs later!

It's always a good idea to use whatever octane the owner's manual specifies.

The engine characteristic that dictates gasoline grade is the compression ratio. If you have a high compression ratio, you'll need premium. Engine control computer set-up and spark plugs can influence pre-ignition characteristics, but compression is king. It is possible that your engine is pinging and you not hear it, vehicles vary.

If you object to buying premium gas, get a car with a bit lower performance.

If your owners manual says "premium" then use premium. I would check your owners manual if you can use lower grades of gasoline.

If you're a risk-taker, wait until you are close to empty and try a couple of gallons of regular grade gasoline. If you experience engine knock, then you need to add a couple of gallon of higher grade gasoline.
