Do any Yaris owners use premium gas ?

[DanMC]

Hi, i was just curious ...i have always believed that premium gas (Shell V Power Ethanol free 91 octane) was a good option when considering long term engine cleaniness...what do you guys think ?...

Been discussed around here lots. Money out the tailpipe is all premium really is. Only those fortunate few that are boosted need to run premium.

I run premium now, but am supercharged :P

I use the highest grade Chevron.
Cleanliness is my goal.

[rningonfumes]

Highest grade doesn't mean the best, it just means the higher octane. You get the same additives in the 87. My Mom thinks the same that more is better when it isn't.

[nemelek]

Tried it a few time and didn't notice any difference in ecomomy or performance.

[beanders]

I have always used premium. There is all kinds of data to support either side.
In my opinion, I have experienced better fuel economy (as occasionally I am at a station that doesn't have premium). Also, I have a 1999 Tacoma that gets better mpg on premium. Does the added cost balance the added MPG? it is hard to tell.

Highest grade means a different concentration of Techron.

[rningonfumes]

Different cars have different octane needs. But you can always expect to find the unsurpassed cleaning power of Techron in all grades of Chevron gasoline. The benefits of Chevron with Techron are numerous.

Higher grades only mean higher Ocatane. Please show me where I can read that they have more addivitives relative to the grade, I spent 10 minutes googling.

I'm just saying like the others that unless you're boosted and need the extra octane, one grade is just a good as the other 2 with relation to additives.

I stick to regular which over here in SOFLA regular is 87 octane. due to gas prices staying high. im glad i only have one car that is required to throw 93 octane in it.

Well I did gas up my Yaris with Shell V Power Gold 91 Octane and so far I would have to say that I am getting worse gas mileage with it. I won't know for sure for a few days as I am not quite empty yet.

So .. the moral of the story, it isn't worth paying the extra 16 cents a liter for the higher octane gas.

[DanMC]

So here in Alberta (some gas stations...only) Petro Canada is selling a 94 Octane super premium gas...it's like .2 cents more than regular premium...just to find out that it is enriched with frickin ethanol...that shiite is bad stuff...so i wrote to Petro Canada to tell them how dissapointed i was that they have to cheat in order to achieve extra buyers, so i will stick with Shell V-Power 91 octane 0% ethanol !...call me crazy but i run V-Power even in my lawn mower(Honda),generators (Honda/Yamaha),other car...well it's an SUV...Pilot (Honda),snow blower...(Honda)...two outboards (Honda) ...so Yaris is near 2000 Km and will return to Shell V-Power !...ohh well.

Just wanted to say Dan .. that I just finished a tankful of Shell VPower 91 Octane "Gold" gasoline. I got the exact same mileage as the "Bronze" Shell gasoline. So in my opinion ... it is NOT worth the extra about 15 cents per liter that you are paying for the supposed better gasoline. So from a mileage point of view .. no benefits. From a performance point of view ... I didn't notice any performance increase. So I would just stick with the 87 Octane gasoline .. as described as acceptable in the owners manual. Just my 2 cents.

[Rockstar]

Over here we only got 91, premium is 98.

[fnkngrv]

I will be running at least 110 next summer...maybe even 125 if I can afford it.

[fnkngrv]

I would suppose the best response would be from someone that has run both 87 and then premium with their ecometer or equivalent to validate either way on a bone stock NA motor.

[Billiam]

Beyond the possibility that some top tier fuels might contain a bit more additives, there is no benefit from running a higher octane than 87 because of the 1NZ's relatively low compression ratio.

[carolinablue]

Higher octane serves no useful purpose unless it is needed to slow ignition in the compression cycle, which is what it was created to do. Don't waste your money.
