total miles a week=280
at 35mpg, fuel used per week is 8 gallons
in los angeles, 91 octane is generally 10 cents more than 89 octane which is 10 cents more than regular 87 octane.
so assuming one uses 87 instead if 91, one saves $1.60 a week(20 cents X 8 gallons) so in a year, one saves $83($1.60 X 52 weeks)
if one uses 89 octane instead of 91 octane, one saves half that or $41.50
Personally saving $40 or $80 is not worth it for me to go against what is recommended by the manufacturer. I not a rich person but can't feel saving $80 per year. It’s a non issue.

Smartcarracer spoke for himself and what he believes and....
stan1174 spoke of what he believes and.....
24-42 has used 87 octane for over 9 months and that what he believes.
BTW: I get 55-60mpg (American gallon)
You are right Stan, It's a non issue.
