Premium Gas

[marcus]

ok i got to add sumthing here.. first of all i been thru a few cars and going to premium give you not just 3% increase on mileage.. you get a lot more. id say close to 10% and thats measured on a cavalier..which i borrowed for 2 weeks and my celica as well which i had for 6 years..and using premium is cleaner than regular gas..now going to 92 or 94 octane which i have tried as well.. not much difference on mileage compare to premium but then again going higher octane really requires adj ur timing to about 10 -15 degree adv. then ull have better take off..and the rules of engagement is adj ment need the feel as well.. makes sure ur engine is not knockin' other wise ur too advance. retard bit by bit..

You cannot make such blanket statements....using premium and getting better milage or performance DEPENDS on the car you put it in, and is not necessarily the same result for all cars.

You run premium in your Yaris sewing machine motor, it will get worse milage, it will produce less power, and it will create more emissions, and burn dirtier. Leave the Premium for the cars that are engineered for it, high compression engines, higher performance cars....premium is not for our Yaris...save your money. Come on guys, get real!

our yaris can run 87 octane or more obviously higher the octane the cleaner it is..it doesnt mean you cannot use more than 87.. its saying the lowest grade you can use is 87 but it does not limit it to 87..and i will guarantee you that you ll get better mileage on premium compare to regular..its jsut the matter of you spending a little bit more for premium.. go with experience and youll see..spend 40 buck or fill up the same liter regular compare to premium and youll see that marcus is right.. oh yah by the way sum cars cannot take 87..most honda is premium and UP!

my experience with premium, except this one, was that my mpg actually was less than average.

which Honda's are you talking about? aside from the upper-end Honda's i would think that they could take regular.

well i guess the honda si.. uses premium or up.. and that is odd where ur getting less mile on premium compare to regular..dont get me wrong..about faster burning fuel which is regular compare to premium..just going by my personal experience with my cars...maybe i wouldnt know unless i buy an expensive cars out there..

Marcus, do you know how octane works? It RETARDS the combustion...why would you do that with a tiny low compression Yaris motor? I think you're still holding on to old Grandpa logic, which dictates that using premium means higher MPG, and lower emissions...this is false unless the car is tuned for the higher octane...you use Octane 93 or 94 in your Yaris you will get lower MPG, and less power from the motor...it is not tuned for higher octane....say goodbye to old thinking....it no longer applies these days. And you're wrong again, most Honda's use regular 87, NOT premium.
