damn wez, I would never put anything but 93oct in my car

 

really? I honestly didnt think it would make a big difference, 80% of the time I put the premium in, but once it got to $53 a tank I thought it would be ok to cut back a little, especially when i get 19mpg...

 

its recommended that we use 93

The engines are built for that particular octane amount, you may be saving a couple bucks but your hurting your engine in the long run

its not a big deal if youve done it a few times, but again, in the long run it will hurt your engine

 

guess i wasn't joking about you hurting your car. When you take shortcuts you only hurt yourself

 

I have a 6mt.

 

i think you're just used to it nevertheless, check everything out and tell us the outcome!

 

Well if I AM used to it, i need mods... lots of them

 

89 octane wasnt good for an engine designed for 91. you probably saved a whopping $100 bucks in the gas difference per year and hurt your engine. I doubt its just that but you never know. Im sure all the loaner g35 sedans all ran 87, I know it put it in.

 

wow, hope everything turns out ok!

 

Wouldnt a lower octane just cause knocking? I read somewhere on this forum that our engines have knocking sensors and so engines running less octane will automatically adjust the timing. Anyway, I will be sure to keep it premium but my main question is if you guys ever got used to the power of your car and thought that it lost power?
