the more expensive cars that i've had got less mpg. then again, the Camry and GTI used always used plus with a tank of premium once-in-a-while, unlike my Yaris, all regular except that one time.

i don't want my Yaris to get used to premium, so i'll test it out again in a month, or when ever the gas prices goes down a bit. premium can get close to 4 bucks here.

Marcus,
2006 Mustang, 2007 Yaris, 2003 Expedition, 2002 Camry, 2004 Camry, 2005 Civic...these ALL get worse gas milage when using premium....but these are not Yaris, so this list and YOUR list is irrelevent. All cars, regardless, will get better milage when one uses the octane the car was tuned for...this is the optimum for best performance. The Yaris will get worse milage with Premium...it's sad that superstitions die hard.... Stop listing other cars....lets talk about the Yaris. YARIS! |

Your regular is only 87?
Ours: Regular - 92 Premium - 95 Optimax™/Ultimate™ - 98 (The name is different with each company) EDIT: Apparently the number is calculated differently and the fuel is the same thing - shown here. |

I agree with the others on that say higher octane will not give better fuel economy (unless the ecu changes the tune because of it). There are a limited number of cars out there that have ECUs that will adjust the tune of the car based on the octane of the fuel.
Usually the ECUs that have this feature only actually work in reverse. They change the tune when you put lower octane fuel in and it hurts performance and fuel economy. This is because those cars were designed to use higher octane fuel to begin with. Anyone that says their car get better mileage with premium is probably just driving it better because they just got raped at the pump. |

i think im getting what other people are sayin..only because you guys already are using 89 and above so it doesnt make the diff..in fact u may lower ur gas mileage as well..in canada yaris is running on 87 octane gas..and 90 % of cars out here.. big difference on 87 to 89 without any exaguration ull notice the diff right away swiching to 89..gas mileage is actually higher with the 89 octane gas..and that is based on my experience with multiple differents cars out here...then again i dont drive high end cars..bmw,lexus,infiniti..etc....

Aren't there some warranty issues with putting 93 octane fuel in a car rated for 87 from the factory? You guys putting high-grade fuel in Yarii better hope we don't find out later on that she doesn't like it. Fuel systems aren't cheap.

i dont know about dealer issue!
you may need to ask ur dealer all i know is it should run atleast 87 octane or up..it didnt say just use 87. then again 93 octane has no diff with 89..the only time it will make the difference is you adjusting or advancing ur timing and that will give you faster acceleration..make sure its not too advance...but the only thing that i dont know is if the yaris ecu will automatically bring the timing down again after you advance it..

Advance timing requires higher octane gas..otherwise ur engine will knock..i have been doing this on my celica for the past 6 years it gives me faster take off with 94 octane from sunoco..but uses more gas though..then i bring it down on winter...1 bolt on the cam to adj. takes less than 2 minutes.. timing gun nessesary..
