my experince with premium
personally i like the premium gas, i've has lots of problems with the regular gas here in ontario. The gas here is mixed with ethanol some times up to 15% except shell premium and i believe pioneer. i was having problems with the gas sensor. Took it to the dealer to find out that the since i was mixing fuel with and without ethanol the fuel turned a white color and had damaged the sensor. i work between montreal and toronto. In Montreal there is no ethanol in the fuel as of yet. Since i had it changed i stop buying regular here in ontario and haven't had the problem since. Also I work for esso and i found out that when you mix ethanol fuel like sunoco with regular fuel with out ethanol turns a white color, and as of yet there no technology to separate the two. But this is my experience and what i found out. Not sure if it is true with what i found, or my car was and isolated incident. Also i did a test with sunoco ultra 94 and shell premium on my last trip to montreal. Between my monteal house and toronto house is 686km with ultra 94 i got 536km and with shell i got 636km same driving style going and return about 120km to 140 km on the 401.

Let's stop the b.s and start posting our mileage figures on the two grades of gas. Enough people checking it should make the results more believable

well i have been switching from prem to reg... so far i got more mileage with the prem then again that could also be driving habit as well..but its about 10-30 km difference for about 38 liters of gas..
here: 1st tank 540km with 39.8l fill up = 38.34mi/gal with regular 87 octane 2nd tank ran 535km fill up 38.4l = 39.37mi/gal with premium 89 octane 3rd tank 540km 37.5l fill up=40.69mi/gal with premium 89 octane 4th tank 570km premium fill up @38.00 liters =42.40 m/gal -15km/liter 89 octane 5th tank went to regular gas..48.2 liters ran 711 km 40% hwy (had to add 10 liters in between), calculated about 6.7l /100km,,41.68m/gal ... i was expecting about 6.0 l/100,,,atleast... |

If you get 10% better gas mileage with premium, as some have stated (36mpg with regular, 40mpg with premium, etc), then you will be driving as far on 10 gallons or premium as you would be on 11 gallons of regular... Stop me if I'm losing anyone... Gas is now above $3 a gallon around my area. You are saving .80 cents if you see 10% better mileage with premium... I'm thinking this is along the lines of the placebo effect, you believe your more expensive purchase is going to help you, so it does... Also, how much do you all drive if an extra $2.20 a tank for premium is breaking your wallet? If you drive 10,000 miles a year at 40 mpg, that is about 23 fillups. That is $50 a YEAR... Sorry for the ramble...but if you believe that premium is helping you, buy it. Scientifically, there is no benefit to running premium in these cars... |

[QUOTE=jdium;101220]Don't understand how you can say that! Scientifically, under load the higher octane allows more timing advance before knock (in a 10.5:1 compression ratio car) which is more efficient, using less fuel for the power needed....not under load I agree with you.

hey, i never said that. hahaha...why is my name highlighted and not jdium?
but yeah, this thread was brought back from the dead. well, i used premium again and got less mpg. but i know that's because i've been using the a/c more. personally, i think i'm just going to stick regular. |

maybe because it would turn potential buyers away from the car, you don't usually associate a modern economy car with premium gasoline... Just a guess anyway! I'm gonna try higher octane fuel just for the heck of it for my next tank...

just my two cents ... i just bought my YARIS a week ago and I LOVE IT .. therefore i use 93 octane .. now does this change anything .. ofcoarse it does .. even if it's only perception .. since my perception is in favor for better gas milage and higher performance i tend to drive a little harder and faster .. just my two cents

Like I stated above. The higher mileage being noted is IMO a placebo type effect. You think higher octane will help, thus it does. If requiring higher octane would turn away potential buyers, why not atleast tell them what everyone in here is saying? Increased octane = increased mpg? Cuz it's not true... |

Go buy a "Maximum Boost" book and it will tell you that a higher octane gas will give you more power compared to lower octane gas.
there is a comparison on the N/A and Turbo there really is a big difference especially if your running RPMs higher than 4500 on N/A... The turbo with high octane gas is damn more powerful than low octane. Also the 106HP (not high performance? I know.) is achieved using high grade high octane gasoline for testing (Since Japan don't have anything lower than 93 octane they even have 120-125 octane) the engine power will drop to 100flywheel HP when you use 87 gas and it will make more gunk to the engine because of the slight combustion difference even with the knock sensors, remember the 1NZ-FE is japan made and tested so It should run 90+octane and will get 51MPG elsewhere except US (may be possible with acetone) which don't have anything higher than 93 basic fuel 100 octane cost like 4.30 vs 3.30 91... (It's new here in the USA and Toyota USA wouldn't put the 91 reccomended fuel since it will hurt sales...) Hope this helps!!!
