regular gas and octane boost?
Our cars are designed to be run on 91 or better, anything less and you get shitty gas mileage and risk frying your pistons.
Ya, seriously, the good octane booster costs $5-$6 a bottle at least. Figure 20 cents more per gallon for super verses regular and your tank being almost completely empty being 15 gallons...it costs $3 more to buy the super. Unless you can find cheap octane booster (good stuff, not STP crappy stuff). It's better to just get the super at the pump...as horrible as it is to spend $40+ to fill up your tank that lasts only 300 - 350 miles if you're lucking.

The Best V8 Stories One Small Block at Time
It's not worth the money to run octane boost instead of 93. I usually run both for a little (really little) kick...
I hate to have to baby it around to keep my gas mileage up...
I'd rather sell my car and get a honda than run 87 octane. Why buy a sports car if you aren't willing to put in the kind of gas it needs? Your car was tuned on 93 octane from the factory and runs 28 degrees timing. I wouldn't use anything less than 91 octane just to save a couple bucks. It's a V8 not a VTEC.
Final octane = (volume of gas*octane of gas)+(volume of booster*octane of booster)
......................................>volume of gas + volume of booster
A bottle of octane booster is so small compared to the volume of gasoline you put it into, that the octane booster would have to have a ridiculously high octane rating to be worth it. It's better to just run 93/91 than the commercially available "octane booster in a bottle." You can get a viable octane increase from certain chemicals but you need to know what you're doing to mix them.
Also, 87 octane in and of itself, is not harmful to your car. Only when you put it under load and it pings will damage result. If your car is a fairly stock daily driver and you just need to get around, you can run 87 IF YOU DON'T GET ON IT. That being said, my car is a 99% stock daily driver but I run 93 because I don't want to limit myself as to when I can and can't play. I bought the car for fun so I don't care that 93 is expensive. However, I'm livid that gas prices have gone up over 2 dollars in 7 years (the majority of it in the last month) when it took it over a century to get over 1 dollar. But that is another rant for another thread.
