I put in some supreme in my car last time i filled up and my gas gauge is kinda weird.. sometimes it says it is empty and then half tank... whats up?

 

Why the hell did you buy supreme? lol

 

yea first off.... live it kinda like this.... high c/r higher octane.. 87, 89, 90 are all fine and are waht u need to be buying... i get 90... helps make sure theres no bad things in the fuel like water.... but ne ways... is it while u shift... cuz when im racing... the gas gauge does that... cuz it sendning so much fuell it take a scond to register it back.. so it goes down form like half a tank to a quarter... adn then it slowly rises back up... i dont undesrtand really wat ur problem is... but if supreme ****ed it up... dont use supreme... u only need to use a higher octane really if u hear a pinging..

 

There's no more gaurantee there will be water in the fuel with 90 than there is with 89 or 87. I'm assuming you mean 91 anyway?

Get 87 Moog. There's no reason to run higher.

 

its not good to get supreme? i always get 93 and no problems.

 

well at my shell it has a 90.... it goes... 87 89 90 91 93 tbhey have 5 different selections... theres ****ing gangsta.. but i use 90 cuz i have a milled head... and my compression changed and it started pinging... so i put better gas in and bam vwalah fix.

 

99ron FTW

 

supreme wont make a difference, all it will do will cost u more money, go for a regular 87 octaine and u will be fine

 

that only reason to really run premium is if you have some kind of forced induction. other than that you are just wasting your time

 

not true, higher octane requires it also when a engine is designed a certain way it needs it also. Like a weaker engine that cant deal with to much knock
