Additives

I looked at gas additives yesterday @ $4-5 dollars a bottle. Not to start a flame war but wouldn't it be cheaper just to buy higher octane at the pump? Or are their other benefits to additives?

It'd be cheaper to use 87 octane. Unless you're modded higher octane isn't needed and more likely you'll just lose mpg, instead of seeing a gain. Overtreating probably isn't good for the oil or the fuel pump. I use one bottle of Chevron Concentrate Plus (treats up to 12 gals) before each 5k OCI.

The amount of additives in premium gas is not very much, in comparison to adding a bottle of cleaner. Also, our Yarii do not benefit from higher octane gas, and in fact I found that my Yaris gets worse milage on premium. It's just not tuned to take advantage of the higher octane. Using premium is like throwing $ out the window.

My yaris performance greatly increased when i used 91 octane gas...93 retards the timing...thus, making it slower, 87 , it feels like its dragging...91 octane and fuel system cleaners regularly..keep it running perfect..
