Do you have the tint on the front windows as well (driver and front passenger side)? Is it too dark at night? |
Down here in Texas, the difference between 89 and 91 is about $.10 a gallon. If you fill up 3 times a month that comes out to @$6/month you are saving--that's nothing. I always run 93--these are high performance engines.
