Best fuel for yaris

[Go4th]

Use the recommended gas. The car is timed for the slower burning octane. The higher octane burns at a higher temp and in the long run will start causing that famous knocking noise in your engine. Sparkplugs and everything else will start feeling the pain of the higher heat and quicker burn, slowly but surely over time. Maybe once or twice a year you can run the higher octane to make you think you’re cleaning it out but it really don’t matter. Toyota did not design the engine to need all those extra additives that they put in the higher octane fuel. You’re wasting money for higher octane. Get the cheap stuff and keep more of your money in your pocket, Toyota recommends it! And your car will thank you for it.

Higher octane fuel actualy has retartant. And the cure for that "famous knocking noise" is to use higher octane fuel. The knocking noise if from using lower octane fuel, not higher.
Our cars can tell the difference between 87 and 93 octane. And when you state "Toyota recommends it" I do not find that entirely true, when they (Toyota) give an octane # for the car it is the minimum recommended.

I agree with Go4th, i tried 93 many times before, it burns out quicker than the 87, I was just wasting my money, higer octane fuel are for high performance cars with a high performance engine, our 1.5L VVT-i is not a high performance engine, so you are just wasting your money

You're joking right?

[stuffy]

i've mentioned this in another thread,

on one of my regular drives, i go past a fuel truck re-filling station and i've noticed trucks from all of the major fuel companies filling up from the same tanks.

that would tell me that this is the exact same fuel they are using and selling under different brand names.
are any addities specific to companies added at the actual stations?
i would doubt it myself.

i've kept track of my mileage since the car was new, always using 87 octane from various companies, i have never noticed a difference in fuel economy depending on the brand of the fuel.
