higher octane fuel - Toyota Yaris Forums

Interesting read... I wonder if the engines here are tuned differently, as 91 octane is the lowest you can get, as well as 95...

i belive it is just a differance in how the octane is rated, i cant remeber any details on it..but i do belive that your lower octane is an equivilent to the north american lower octanes...

I find it strange ~ That you guys are talking about 87.....89.....91.....93 octane fuel ~

Here in Australia we have 95.....98 and 100 octane fuel ~ I fill up with 98 octane fuel and there is quite a big difference with the regular fuel ~

That's my opinion anyway ~

North America measures octane differently than the rest of the world so it's numbers do look lower. That said, I'm pretty sure american 87octane is slightly lower than the average regular in Europe. Probably why (or because) european cars have high compression rates, and american cars run a pathetic inefficient 8.5 or 9:1.

Low compression ratios isn't all bad. There are advantages to being able to run on dirt.
