i usually put the regular grade gas into my integra (96) but wouldn't mind going up one to try it out. my gas tank is right on empty and was wondering if it would cause any problems to switch up a grade to test it out. im not saying ill stick with it so i might go back down to the lower grade. can anyone explain if this is alright to do?


and for the brakes...when im on the highway and pass approximately 130km/h, whenever i turn the wheel the slightest bit to the right, it makes a squeeling/squeeking sound and is super annoying, what could it be?

 

Do you have an LS or GS-R? Personally I don't use anything lower than 93 octane on my GS-R.

 

Yeah if you have an ls there is no point since the car was not engineered to perform on higher octance but if it a gsr you need to put higher grade in otherwise it can "hurt engine life, performance, and hondas reliablility"
