I pay about 2 bucks a gal for premium here, cost me 30 bucks to fill up my s13. My dad took my car the other day and put 10 dollars worth of crap in it and I noticed a big difference, definitely pingy. so when the tank was near empty I poured some FI cleaner in there and filled up w/ premium, I think its worth the extra few bucks per tankfull to have a smoother running engine
