pump gas?
alright, im cheap and broke
i put 87 octane in my car because its cheap, would i notice any difference in horsepower if i put the 92 octane swamp water from kentucky in it??
what about octane boosters to get around 95 or 97 octane, i read somewhere about a magazine putting 100 octane race gas with a buncha bolt ons making close to 350 horse at the wheels naturally aspirated
what gas do you guys fill up with

no need to discuss, i doubt you ever read the stickies or searched. everyone on here uses premium 91+ octane.
if you don't want to or can't afford it, then use 87. nobody on here will recommend it though. theres also no way to get 350 hp at the wheels with 100 octane either.

you realize that it saved you a whole $3 right? If you don't have 3 dollars to spare, seriously consider selling the Z, its monthly payment is too high for you.

Yeah... they're being harsh, but its true. The Z holds ~20 gallons of gas. 87 octane is usually ~20 cents cheaper per gallon. You saved all of $4 PER TANK.
Honestly, I think there are many ways to save MUCH more money than that on other things. Selling your Z for a 10 year old Honda Civic would save you tens of thousands of dollars immediately, and you'll save much more by getting better gas mileage.
But if you're dead set on putting low-end gas in a Z, then I guess I'll have to tell you that your gas mileage will decrease with using the 87 octane, so you're probably not going to save as much money as you hope. Plus you're not going to have as much horsepower. Plus you risk damaging or preemptively wearing out your engine/fuel system which will cost you THOUSANDS of dollars, which your $4 per tank WILL NOT be able to cover. To put this in perspective, you'd have to go through ONE THOUSAND tanks to get $4,000, which your new engine may cost you. If you get 300 miles to the tank (perfectly reasonable, unless you never let your foot off of the accelerator), then you'll have to put 300,000 miles on the car to cover the cost of the damage you'll eventually do by putting the cheaper gas in there. Trust me, the car WILL NOT last that long on the cheaper gas.
But, then again, its your money.

dude if you dont have the money for premium, just sell your car back.
Im broke as hell, no mods after over 4.5 years of ownership but ive never stooped that low. How much money are you really saving?
go donate some sperm, they give you like a $100 for that ****. judging by the calculation above, you should be able to ride that $100 out for atleast 20-25 tanks of premium. get a grip, man(pun intended)

For horsepower between the octane ratings:
Up to premium grade (~92 octane), you'll see a horsepower increase. However, getting 100 octane will net you next to nothing. This is because the engine's ECU is tuned specifically to take advantage of 92 octane. If you get your ECU reprogrammed for 100 octane, you'll see a bit of extra performance, but probably not much more than 10 horsepower or so (unless you're car has forced induction or *serious* N/A mods).

Not to mention buying 87 octane in the summer is WORSE than any other time... I have known about "hot fuel" for years... The gas companies know many ways to **** the consumer..
