I usually get 87, but i got 89 once and it was about the same with mpg. since I have had my car i've always used shell gas, don't plan on using another brand. I've always been weird with gas and my cars, always fill up the same place, usually the same pump. Unless of course im on a trip, but then ill still use shell.

Using higher octane than recommended will NOT make the engine knock*. It will make it less likely to knock. Higher octane = more stable and less likely to prematurely combust.
Members in this thread are correct in saying that you will most likely have no benefit from increasing the octane rating on the fuel (unless your car knocks at the recommended amount). The top fuels (98 RON) are there to replace leaded petrol. Back in the day, lead was THE way to boost octane. Now we can achieve higher octane ratings without it, there is no need to burn lead in old cars. *Heh, I just read the last couple of pages and I don't think anyone said it would. Nevermind then. |

Reality Check Folks: Our small 1.5L low compression, non-turbo, low, low performance Yaris cars are the LAST car to get any benefit from high octane gas. Lets get real here folks....most of the "benefits" many think they get is all in their heads....anyone hear of the Placebo effect? Funny how age comes into play on this issue. My two teenaged daughters, both drivers, have several male friends in their age group, that all drive late model Japanese cars that DON'T require high octane, yet they ALL only use high octane gas, as they all have this dillusion of premium giving more "power" and more "speed". Teenagers! Youth! LOL Save your money, and be happy. |

Don't be so quick to read more into the words, then what is literally meant. Also, to suggest as a remedy, to use higher octane than called for in the manual, a way to remove knocking is plain wrong. It would be far better to take the car in and determine why it is knocking at the required octane, and to remedy the problem. Going up in octane is a band-aide that only masks a real problem. |

Since this topic is back alive, I should mention that I tried a higher octane in my last two tanks, with no noticeable increase in mileage and/or performance. Mind you, it was an ethanol mix, so it may have had a part to play. You won't blow up your engine with higher octane, but whatever benefits probably do not outweigh the extra cost.

I know the sound you're talking about....my old '97 Camry did the same...that sound is NOT pinging...it is just the fuel injectors doing their thing....yea, my Yaris does the same thing when I drive near a wall....again, not pinging, just valve and injector noise....no worries. |

My take:
Got a cheap car? Buy cheap gas. Use "87 or higher" (per Yaris manual). Maintain your car diligently and drive sensibly.
