Lol, another gas octane thread .

I use 91 octane gas simply because our cars were intended to use it. And it's only a few bucks more than pumping 87 octane for a full tank.

 

thanks and i WILL use 91 for now on and also just wondering what exactly is knocking of the engine like whats it feel like or sound like? sorry if that was a dumb question but im trying to know what the correct statement of it is?

 

I know that a tune is required to get the most power when using a higher octane. But, if I were to put race fuel in my car right now I'm fairly certain I would see a gain. I'm talking about 100+ octane. I doubt going from 91 to 93 would have any effect.

 

This should answer all your questions on engine knock.

Which is why I specified pump gas in my original reply.

 

ok yea i get what a knock is now, but i just went to youtube and i am disapointed that i type in engine knocking and the first video up is a G35 WTF arent out engines on the top 10 engine list?

 

top 10? hahaha i wish. Use premium only. as someone said before, running 89 can cause your engine to ping and cause engine knock which CAN hurt your motor. whoever said that 89 will not hurt your motor if the engine calls for premium made a false statement. whoever said running premium on a car that calls for 87 will do nothing for performance, +1 to you. octane boosters dont do squat for our G's either so +1 to whoever said that. some people dont know this, but shell V-power is Nitrogen-Enriched. thats what puts shell in a different bracket than other gas

 

yea im going to switch asap but yea the vq35 engines did make the top 10 best engines ever made list from 03-07 i think which is good

 

also with using v-power shouldnt if get better mpg and performance then what im getting with 89 oct. since the fuel burns slower with 91?

 

yes you will get better gas mileage and performance. you will notice better gas mileage but you wont notice better performance eventhough its there. you will notice your car running better tho. keep us posted

 

+1, you'll also get less deposits in your engine by using the recommended octane gas. With running 89 octane for so long, I think you'll be pleasantly surprised on how much better your car is going to run after a couple fill ups.

 

HELL YEA im sooo excited im like a kid in a candy store with getting better mpg and performance and just have my car run better. iv always thought 89 wasnt cutting it but yea thanks yal and will keep it posted

 

Better gas mileage at a higher per gallon price. The benefit is negated.

 

91 v power bro

 

Our cars recommend 91 or higher.
