i got my car about 3 months ago and did not realize that i was supposed to be using premium gas. therefore, i have been using regular. should i notice any difference with premium other than a thinner wallet? thanks!

 

yea better performace and pick up even with a stock setup..I use 93 or sometimes even 94

 

since ur car is used and has certain miles there, it won't be a big factor

in fact a car is fine with regular when it's getting old and has no affect at all

if you are satisfied with the performance with regular gas then there you go~ =)

 

It's recommended for a reason. Use it.
