when it comes to gas , dont cheap out. used the 91, it might hurt your pocket book right now, but in the long run you will be very happy.
my best way to compromise is with food. lol. in order for me to do more frequent tune ups and higher octane. i dont eat out that much no more. currently , 80% of my diet is fruits and veggie. and i lost 27 lbs in 3 month for that, lmao.
i plan to drive my legend until the day i die. i might buy 1 or 2 more car within 10 years. but i aint getting rid of my legend. i went through with it so much, good or bad, that no one take my legend from me.
