First let me introduce myself I'm a newbie from Austin, Texas
Looking at buying a 08/09 civic si or 09 ex and was worried about having to buy premium all the time since it is 1.00 more a gall. The main reason I'm buying a car and selling my truck is to get better mpg. I was willing sacrifice mpg of the si vs the ex because the fun factor of driving it. But since I found out it suppose to use premium the overall cost for a 5 yr period for fuel went way up. Close to 4000 more than the civic ex fuel cost...
I friend told me today his sister in law has a 07 or 08 civic si and all she uses is regular...
I realize it is probably bc of the needing higher octane but at a 1.00 more a gallon it seems cheaper to add octane boost at every filling..
Does any use just regular or regular plus octane boost or mix regular and premium???
Any help would be much appreciated...
Thanks
